Product description:
The LED-drive is being directly connected to the 230V mains supply via feeder clamps. Irrespective of the number of Power LEDs, the output current is being re-adjusted to a constant value. Nevertheless, the specified maximum output power must not be exceeded. Depending on their type, the devices supply the required constant current at the output. Compliance with the guidelines for SELV current circuits is ensured. The device is short-circuit proof and resistant against overtemperatures, no-load and overload conditions.

The brightness control of the LEDs works with an PWM module via the integrated 1-10V interface. These control inputs can be operated alternatively with an electronic potentiometer (50k?) or a DC control voltage 1-10V.

The devices are equipped with a separate input designed for temperature regulation to control the load. A NTC resistor can be connected. In case the specified temperature is exceeded, the device adjusts the current or siwtches off in order to prevent damages. For this purpose, the NTC resistor is being connected to clamps 4 and 6.

Hints for the application:
Following LEDs can be operated with the devices (considering the maximum output power of the particular device). Their number also depends on the used LEDs (light colours):

1. LED-drive-35 (HV-Type) (350mA):	1 ... 12 x 1W in series
2. LED-drive-35 (350mA)	1 ... 7 x 1W in series
3. LED-drive-70 (700mA):	1 ... 6 x 3W in series
4. LED-drive-100 (1000mA):	1 ... 6 x 3W in series
5. LED-drive-100 (1000mA):	1 ... 3 x 5W in series
