Design and mode of operation HALOTRONIC® transformers are electronic transformers which replace conventional transformers for operating 12 V tungsten-halogen lamps. hey have about 60 % of the volume, 15 % of the weight and 30 % of T the power loss of conventional transformers. he diagram below shows the way in which the HALOTRONIC® transT former works. The mains voltage is rectified, converted into a high-frequency voltage in the chopper, converted back into an ac voltage and fed to an output converter which converts it into a 12 V ac-voltage. A filter ensures that radio interference standards are met and helps make the unit immune to interference. Block diagram 230-240 V Fig. 1 ecause HALOTRONIC® transformers have such a low power loss, B they generate much less heat than conventional transformers. In partial load operation, HALOTRONIC® transformers do not produce overvoltages so even in this mode of operation there is no reduction in the life of the lamp. Electronic transformers are not suitable for any other load than low voltage halogen lamps. 2.

Performance 3.1 Electrical and photo- metric data as a function of mains voltage and lamp wattage ALOTRONIC® is designed for a 230 V or 230 – 240 V supply depending H on the model. The diagram on the left below shows the situation for a conventional 100 VA transformer not suitable for partial load operation. When operating a 20 W lamp for example, the high secondary voltage (> 13.5 V) causes lamp life to be sharply reduced. This increase in the operating voltage of the lamp of more than 10 % leads to a reduction of about 60 % in the life of the lamp. HALOTRONIC® on the other hand operates lamps reliably over the entire partial load range. One advantage of partial load operation is that the failure of one lamp in a multi-lamp luminaire will not lead to the premature failure of the remaining lamps. e Fig. 5 3.2 Permissible mains voltage range For a 230 (240) V ac supply, the nominal supply voltage is 230 Vrms (240 Vrms). Overvoltages of up to 6 % are permissible. If the voltage is more than 6 % higher correct operation cannot be guaranteed and HALOTRONIC® may be damaged beyond repair. Every HALOTRONIC® transformer is protected (to EN 61547 or IEC 61547) against transient mains overvoltages (these occur, for example, when inductive loads such as fluorescent lamps operated with conventional control gear are switched off). 3.3 Operation on dc supplies The models indicated by the symbol ~= or 0 Hz in the technical data can be operated on a dc supply and are therefore suitable for use in emergency lighting to VDE 0108. Lamps connected to HALOTRONIC® transformers emit the same luminous flux whether an ac or dc supply is used. The permissible dc voltage range is 154 V to 244 V1). 3.4 Permissible temperature HALOTRONIC® transformers operate reliably within the temperature range range specified for each particular model (see technical data). Excessive temperatures will cause electronic components to fail prematurely and the transformer will not be able to achieve its specified life expectancy.

When installing HALOTRONIC® inside a luminaire, the measuring point temperature on the casing (tc) t c is the crucial factor. If units without a casing are installed in a luminaire, temperature tc must be measured on certain electronic components. The limit temperatures on the components specified for the particular model must not be exceeded. (see Fig. 6).

Minimum load ALOTRONIC® transformers must be operated with a lamp wattage H 1,5 mm 5 mm which corresponds at least to the minimum load (see technical data). 53 mm If this minimum load is not reached, harmonics and/or radio intertc ference values may exceed the permissible thresholds and output voltage will fall considerably (see Fig. 7).

All the units have electronic cut-outs. These ensure that the units will not be destroyed by a short-circuit1). The units will be fully operational again once the cause of the short-circuit has been eliminated. 3.8 Overload/overtem- perature protection 3.9 Safety, electrical isolationHALOTRONIC® transformers meet the requirements relating to safety transformers for safety extra-low voltage2). The dielectric strength (electrical isolation) between the primary and secondary sides is tested on each unit at a voltage of 4 kV. The transformers are also constructed and approved in accordance with EN 61347-1 & EN 61347-2-2 (Electronic Converters, Safety). HALOTRONIC® units are equipped with electronic overload protection. Even if the overload persists, there will be no damage to the unit. The output power is either reduced or automatically disconnected. For a 2 m long cable, the overload protection circuit will be triggered at around twice the maximum permissible load1). If external heat source cause the temperature at the unit to exceed the specified maximum, they will automatically reduce their output to protect themselves1). The user will notice a drop in the luminous flux of the lamps supplied by the transformers. A pplies only if supplied with 50 Hz ac voltage (the HT ...

This means that they are protected against the external influences of high-frequency fields, discharge of static electricity and transient overvoltages in the mains supply, as defined in EN 61547. 3.13 Noise emission ALOTRONIC® units are almost silent in operation. In a dimmed mode H noise could occur if e.g. mounted on a resonant part. In general a trailing edge dimmer should be prefered for a quiet operation. E.g. under worst case conditions (mounted on a wooden board), HT 70 L emits a sound power level LWA of less than 10 dB (A) in undimmed mode. Even in dimmed mode with a trailing edge dimmer in the least favourable dimmer setting, the sound power level is normally less than 20 dB (A)1). By comparison, acceptable sound pressure levels are as follows: • for a quiet living room: 35 dB (A) • for an office: 35 dB (A) 3.14 Parallel/series connections HALOTRONIC® units can be connected in parallel on the primary side. In the case of the HT ... L, HT ... LF and HTM 150 models, the second pair of terminals can be used on the primary side. The maximal current must not exceed 16 A. In professional applications, several units can therefore be connected to a single dimmer. In contrast to conventional transformers, however, HALOTRONIC® transformers cannot be connected in parallel on the secondary side because they would be overloaded. Series connection to operate 24 V lamps is not permitted. Switching or dimming on the secondary side is also not allowed. r Fig. 9 1) r T est set-up: dimmer located outside the room, measurements taken on one unit, operation at maximum rated load. 12 3.15 Start-up current Einschaltstrom Îmax [A] Thetable 3 shows the peak values for the maximum start-up current Îmax (time: 10 ms, half sine wave) for a cold lamp.

HALOTRONIC® units are designed so that at the maximum permissible device temperature (tc max.) a failure rate of fewer than 2 per thousand per 1000 hours of operation can be expected. This corresponds to a life of 50,000 hours at a percentage component failure of less than 10 % (HTM and HTN: 30,000 hours at a percentage component failure of less than 10 %). By lowering the operating temperature by 10 degrees celcius it is nearly possible to double the lifetime. 13 4.1 Luminaires for HALOTRONIC® Fixed spothights Power rail spotlights Desk lights Surface-mounted ceiling luminaires 4.2 Main advantages Comfort: ® of using HALOTRONIC • Just like the cased HALOTRONIC® units, the circuit boards have much smaller dimensions and much lower weights than conventional units • Silentdimming; with different dimmers depending on the type (see also on page 12) • Installation in false ceilings 14 Areas of application: • Foyers/reception areas Passages/corridors • Sales areas and exhibition rooms • Individual offices/ conference rooms • Accent lighting • Decorative lighting Economy: • Protective operation throughout the entire partial load range • 2/3 less heat generated by the luminaire • Ready for installation with no additional fusing required • Lower power consumption than a conventional transformer Safety: • The units offer an electronically reversible cut-out to protect against short circuits, overloads and overtemperature • All units are ENEC and/or VDE tested • Suitable without any additional measures for Iuminaires of protection class II and III (for L models) and for Iuminaires with and symbols or with and symbols • The units comply with European standards for safety, operation and EMC • Direct current operation for emergency lighting systems to VDE 0108 possible with HT ... L-types (see 3.3) 15 5. Notes on independent installation and installation in luminaires 5.1 Maximum 12 V cable length The length of 12 V cables must be less than 2 m to comply with radio interference limit values. This means that luminaires can be installed within a radius of 2 m around the electronic transformer. There is no advantage in terms of radio interference suppression in using shielded cables for the secondary line since both secondary poles carry high frequency, which makes shielding impossible. Note also that long secondary cable lengths (more than 2 m) and/or non-parallel or twisted wires (large loops) produce a large inductance for the electronic transformer. Because of the associated loss of voltage on the cables, this leads to a low lamp voltage.

Keep HF cables and mains cables as far away from one another as possible (e.g. 5 to 10 cm). This avoids mutual interference between mains and lamp cables. 3.Lay HF cables away from any metal surfaces (if possible several cm away) to reduce capacitative interference. 4.If two long single HF cables are unavoidable they must be twisted together. 5.Keep mains cables in the luminaire as short as possible to reduce interference. 6.Do not lay mains cables too close to the transformer (this applies in particular to through-wiring). 7.Avoid crossing mains cables and lamp cables; if this is not possible, they should cross at right angles (to reduce HF interference on the mains cable). able penetrations through metal components should never be left C unprotected and should be fitted with additional insulation (sleeve, grommet, edge protector, etc.). lectronic transformers can be installed in a wide variety of places, E including suspended ceilings, furniture, luminaires and tube systems. The transformers may be mounted on wood since the units comply with the requirements for labelling according to VDE 0710 and VDE 0100 Part 559. If HALOTRONIC® is to be dimmed it should be installed away from resonating surfaces so that any dimming noise is not magnified by vibrations. 18 5.4 Installation correct wiring Fig. 11 5.4.1 Ease of installation incorrect wiring L models: • Blanking caps on the primary and secondary sides can be easily levered off with a screwdriver, saving you considerable time and effort. • Two pairs of terminals on the primary side for mains looping from unit to unit; a maximum current of 16 A may be looped through. • One and the same screwdriver can be used to lever off the blanking caps, connect the wires and adjust the strain relief. • Strain relief possible on the primary side for e.g. two NYM 3x1.5 mm2 cables, three pairs of terminals on the secondary side for the parallel connection of three luminaires. • Sufficient cable space in front of the screw terminals. LF models: • Extremely low-profile design • Two pairs of terminals on the primary side for mains looping through • Strain relief possible on the primary side for two NYM 3x1.5 mm2 cables • Two pairs of terminals on the secondary side for the parallel connection of two luminaires HT…L Fig. 12 19 HTM • Standard unit with functional, compact design for small spaces • Cable clamp suitable for different cabels and cross sections • HTM 70/105: One pair of terminals on the primary side and two pairs on secondary sides for connection of two luminaires • HTM 150: Two pairs of terminals on the primay side for mains looping. Three pairs of terminals on the secondary side for connection of up to six luminaires. 1 2 3 Fig. 13 5.4.2 Space needed to install The distance needed between the actual ceiling and the suspended stand alone transformersceiling will vary according to the size of the opening (see Table 5).

There is no protection against water or humidity (IP 20). 5.7 Integration in luminaires If HALOTRONIC® transformers, particularly the uncased units, are to be installed in luminaires, the luminaire manufacturer is responsible for complying with the necessary clearances and leakage paths and for providing adequate protection against electrical shock, as defined in EN 60598. Since all HALOTRONIC® models are protection class II devices, radio interference values must be checked if the units are installed in metallic protection class I luminaires. If necessary, external filters must be fitted to bring these values within the permitted range. 5.8 The units generate little heat, but this heat still has to be dissipated. To avoid overheating, make sure that the electronic transformer is not installed too close to a heat source (distance between lamp and transformer: 30 cm). If the units are to be installed in luminaires, take suitable steps to ensure there is good heat transfer between the HALOTRONIC® unit and the luminaire casing. Temperature tc at the test point must be measured to ensure that it does not exceed its maximum permissible value. Low unit temperatures prolong the life of the unit (see also 3.17). Instruments for secondaryAn instrument for secondary voltage measurement must allow voltage measurement measurement of the true rms value and have a bandwidth of at least 500 kHz (-3 dB). Any other instrument will give incorrect measurements. Reference Standard Pack 21 6. C omparison of stand alone units HT... L 230 V 0/50 Hz HT...
