Operating Instruction

1. Carefully connect appropriate pins of the LED with LED connection terminal block (4) till tight fixation.

Note! Terminal block header marked with “LED +” must be connected to the appropriate pin of an

LED (marked with a red point). Improper connection may cause LED damage.

Note! LED case must be electrically isolated from the ground.

2. If necessary, make all external connections with synchronization input (8) and synchronization

output (9).

3. Select required regime using pulse duration, frequency and LED current adjustment jumpers (5, 6 and

7 respectively). You can also adjust frequency with an external signal source connecting it to the

synchronization input.

4. Connect power supply to the power input (1). LED current indicator (green) (3) will be turned on if

everything is connected properly. In case of circuit break red indicator (2) will be turned on and LED

current indicator (3) will be pulsing till the problem will be solved.

5. To observe the temperature connect any voltage measuring device to temperature observation voltage

output terminal block (10). Note that since every LED has a unique current-voltage characteristic,

correspondence between output voltage and temperature will be different depending on measured

LED.

Note!

Please follow the requirements presented in the table of “Main Characteristics” and

“Adjustable Parameters” to provide driver’s faultless operation.
