Operating Mode Description

PCB-mdriver-P driver works in a Pulse mode. This mode provides LED maximum peak optical power.

LED current, pulse duration and frequency are fixed to 2 A, 5 µs and 2 kHz.

Operating Instruction

1. Securely solder the appropriate pins of the LED with LED connection contacts (1).

Note!

Contact marked with “LED +” must be connected to the appropriate pin of an LED (marked with

a red dot). Improper connection may cause LED damage.

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

2. If you use PCB-sdetect-3P synchronous detector, connect the PCB-mdriver-P

’s synchronization output

contacts (2) with synchronization input terminal block.

3. If necessary, make all the connections of other boards (synchronous detector, thermocontroller etc.)

following the appropriate instructions manuals. Before turning them on check the required connections

and modes:

Synchronous detector:

Thermocontroller:

 Photodiode input connection

 Preamplifier power output connection

 Averaging time and signal gain selection

 External signal observing device connection

 Thermistor / PCB-driver-51 temperature

observation block input connection

 Thermocooler output connection

 External connections (if necessary)

4. Connect 5V stabilised power supply to the power input (3).
