HALOTRONIC® Electronic transformers for 12 V halogen lamps • Optimum lamp life • Compact for small spaces • Reversible switch off in case of shortcircuits, overload and overtemperature • Dimming on the primary side is possible. A corresponding dimmer has to be used (suitable dimmers see table) Connecting the transformers to the lamps • Ensure that the lamp load is within the output range of the transformers (see table) • Transformers can be connected in parallel on the primary side (fig. 1a) • Do not connect the transformers in parallel or series on the secondary side (fig. 1b) • The maximum load of the transformer can be connected to any of the lampside terminal pairs (except HTL 225) • For units installed in fixtures the luminaire manufacturer is responsible for RFI-compliance Wiring • In accordance with the EN 60598 standard, the recommended connecting cables (see table) must be held firmly by the cable clamp to prevent it from being pushed or pulled • Secondary side: cable length maximum 2 m, minimum 0.3 m (fig. 2 and 3) • To prevent radio interference keep lamp cables as short as possible, keep them away from metal surfaces and keep them separated as far as possible from mains cables (fig. 2 and 3: angles ≥ 90°). Do not route cables along the transformers • When using single leads of a cable, secondary wires have to be twisted in pairs Temperatures • Avoid high temperatures. Do not place the transformers close to the lamp (minimum distance 0.3 m). Maximum permissible ambient temperature must not be exceeded (see table). Make sure there is adequate space to avoid a build-up of heat. In critical installations the temperature at tc has to be controlled correct Caution • Transformers must be installed by a qualified electrician • Electronic transformers are not suitable for any other load than low voltage halogen lamps • No switching or dimming on secondary side incorrect 1. a 1. b HALOTRONIC 105 W 100 W HALOTRONIC 105 W 120 W HALOTRONIC 105 W 35 W HALOTRONIC 105 W 10 W HALOTRONIC 105 W 35 W 35 W 35 W HALOTRONIC 105 W HALOTRONIC 105 W 2. 3.
