PCB-driver-41

rev 1.2 22.04.2015

Description

PCB-driver-41 driver is designed as power supply of Mid-IR LEDs. It provides pulse mode operation,

which can be adjusted by jumpers (different values of current, frequency and pulse duration can be

triggered).

A synchronization input terminal block allows synchronizing the driver with an external device, with two

or more drivers simultaneously, or setting custom frequency of the LED

A synchronization output terminal block gives the possibility of synchronization with an external device.

In case of circuit brake, a safety system for prevention of LED damage is included.

Features

• Pulse mode operation (for maximum peak optical power)

• Adjustment of LED current amplitude, frequency and pulse duration via driver’s jumpers

• Synchronization input terminal block which allows:

- synchronizing driver with an external device (synchronous detector etc.)

- synchronizing two or more drivers simultaneously

- setting custom frequency of the LED signal

• Possibility of synchronization with an external device with the help of synchronization output

terminal block.

• Safety system for prevention of LED damage in case of circuit brake
