_ OT Programmer hardware for configuration of 2DIM ECGs necessary
_ Programmable via Tuner4TRONIC software
Additional product information
_ 800 mA type: Default output current is 700 mA without any resistor connected to the LEDset port.
_ 1250 mA type: Default output current is 1000 mA without any resistor connected to the LEDset port.
_ 1400 mA type: Default output current is 1000 mA without any resistor connected to the LEDset port.
_ The LEDset2 interface is disabled by default and needs to be activated by the programming software. In this case the LEDset2
interface is activated the external thermal protection feature is disabled.
_ The driver withstands an input voltage of up to 350 Vac for a maximum of two hours.
_ The driver may shut down the load if the input voltage of the load is below the allowed minimum output voltage until the
short circuit is removed or the correct load is connected and a power off/on cycle is performed.
_ In case the input voltage of the load exceeds the output voltage range of the driver, it automatically reduces the output
current to keep the output voltage controlled to the maximum allowed output voltage.
_ The driver automatically reduces the output current in case the maximum allowed output power is exceeded, as long as the
input voltage of the load is within the declared output voltage range of the driver. In all other cases the driver may shut down
the load.
_ The driver may shut down in case no load is connected to the driver output until the correct load is connected and a power
off/on cycle is performed. Hot-plug of the load or external switching on the secondary side is not allowed.
_ The EQUI (housing) shall be connected to the heat sink of the LED module to improve the surge withstand capability of the
system and EMI in critical luminaires.
_ By default the LEDset / NTCset / Prog+ port is set as NTCset port in resistor based mode with following values: start derating:
6.3 kOhm, end derating 5.0 kOhm, derating level 50 %.
_ The default dimming mode is 0…10 V, AstroDIM-PD is disabled.- 0…10 V: 30 % minimum dimming level
_ The constant lumen feature is disabled by default.
_ If any output level is below the physical min level, the physical min level will be used.

Product datasheet
Dimming down to 10 % of the maximum rated output current could be enabled through the programming software, but the
compliance with EN 61000-3-2 must be checked below 30 %.
_ The driver is intended for built-in use. The luminaire manufacturer is responsible to prevent direct exposure for example to
sunlight, water, snow, ice.
_ Time to reach the set output current upon start-up is less than 4 s.
_ Programming of the driver via Prog+ and Prog- is only allowed without powering it via L/N.
_ For further details please consult the 2DIMLT2 application guide.
