The documents are available on the internet (www.osram.com). Operating Window General Notes • • • • • • • • • The unit must be installed by a qualified electrician. Do not service the unit when the mains voltage is connected. Do not use damaged or defective contacts or housings. Do not use damaged units. The unit is intended for built-in use. The luminaire manufacturer is responsible to prevent direct exposure for example to sunlight, water, snow, ice. The luminaire manufacturer is responsible for its own luminaire design, this has to comply with all relevant safety standards. The maximum temperature should never exceed Tc(max) at the case temperature point (tc). Cap off all unused wires to prevent accidental contact with other parts of the luminaire and driver. Programmed parameters needs to be verified before usage (see restrictions: 0-10V/AstroDIM Features). 1 Edition:3rd August 2015 Ver.: 1.2 Status: Released C10419714 G10549898 OPTOTRONIC® LED Power Supply OT 100/120-277/800 2DIMLT2 P Instruction Sheet Default Parameter Settings Dimming Mode Output Current Temperature Protection Constant Lumen Lamp Operating Time End of Life 0-10V 0 -10 V 700 mA Enabled; Resistor based; Start: 6,3 kOhm; End: 5,0 kOhm; Level 50% OFF 0 khrs OFF Minimum Dimming Level 30 % Programming This unit is fully programmable via OSRAM OT Programmer with the help of the Tuner4TRONIC Programming of the driver via Prog+ and Prog- is only allowed without powering it via L/N. ® software. The new programmed parameters would get valid with the next power on cycle. Further details are available in the application guide for the 2DIMLT2 family. Thermal Protection This unit offers resistor based mode to set the thermal protection of the LED module or the luminaire. An external temperature sensor (e.g. NTC) must be connected between LED- and NTCset. This feature is recommended to guarantee long lifetime of the LED luminaire. Resistor based If the NTC value falls below the “start derating” resistance value, the unit starts derating down to set “derating level” at the “end derating” value. Start Derating Temperature [6,3 kOhm] 56 °C 66 °C 75 °C 85 °C NTC Type 22K 33k 47k 68k End Derating, Switch On Temperature [5,0 kOhm] 62 °C 72 °C 83 °C 92 °C The temperature threshold would vary on the used NTC component and tolerance. 2 Edition:3rd August 2015 Ver.: 1.2 Status: Released C10419714 G10549898 OPTOTRONIC® LED Power Supply OT 100/120-277/800 2DIMLT2 P Instruction Sheet LEDset2 (LT2) The unit offers two operating modes: “Fixed Current” or “LEDset2”. By default the “Fixed Current” Mode is enabled. ® In case the LEDset2 interface is activated the external thermal protection feature is disabled. With the Tuner4TRONIC it is feasible to set one of those two modes.

The device will follow the dimming scheme of each feature. When the output level in the dimming scheme is below the minimum physical dimming level (minPHY), the minimum physical dimming level will be used. Insulation The unit has double/reinforced insulation from primary to the secondary side and double/reinforced insulation between all electronic parts and the chassis.

The unit is suitable for protection class I and II luminaires. The connection of the EQUI (=housing) to protective earth is only necessary in protection class I luminaires [3]. The connection of the EQUI (=housing) to Protective Earth is necessary to meet UL approbation in case of connection to dead metal parts. Maximum output cable length is limited by EMI and cross diameter. This control gear is not suitable to disconnect the LED load during normal operation. Input and Output Wire length: 280 mm +/- 20 mm This control gear is inherently protected against wrong wiring on the output side. The wrong connections between LED+ with LT2/NTCset could damage irreversibly the ECG. All the other wrong wirings on the output, once removed, make the ECG work regularly. The NTCset/LT2, LED+ and LED-, 0-10V cables are ESD protected up to 4kV according IEC 61000-4-2. The startup time to reach the set output current is less than 5 s.
