LED Driver D-11 Operating instructions

1.

Insert AC/DC adapter into connector "+12V DC" (Attention on voltage polarity).

2.

If necessary connect "Connector for synchronizing pulses" with selective amplifier of the detector signal (Attention on

voltage polarity).

3.

Insert a LED into connector "LED" (Attention on voltage polarity - + to the red point on the LED package).

4.

Select operating mode - "QCW" or "Pulse" (switch "Operating mode"). Green LED will indicate selected mode.

Installed frequency is 0.5 kHz. If you select pulse mode, installed pulse duration is 1 ms. Customer can specify in his

order other frequency and/or pulse duration.

5.

Set pozition "0" on Switch "Current"

6.

Switch On Driver (switch On/Off). Green LED "Working" will indicate that current is flowing. If after switching on

current is not flowing red LED "Break" will indicate break of the circuit. That situation can take place if testing

Infrared LED is damaged. If Customer order Driver D-11 together with infrared LEDs

currents for quasi-CW and pulse modes are fixed (usually 200 mA in QCW and 1 A in pulse mode).
