Description
The PLD-CW-2000/PLD-CW-2000-ZIF is a constant current laser diode driver for powering 10/14-pin butterfly laser diode modules for applications, which require precision low ripple constant current regulation.
The driver circuitry operates from a single 5Vdc power source. The driver supplies a bidirectional proportional-integral-derivative (PID) thermoelectric cooler controller (TEC) with current capability of 4A and voltage capability of 4V.
The main parameters of PLD-CW-2000/PLD-CW-2000-ZIF (output current, temperature set, monitor photodiode signal) are controlled by computer interface. The GUI can control multiple drivers connected by CAN/USB hub.
The driver supports full amplitude modulation of drive current by an external analog 0…5V and TTL signals.
Driver has landing pads for soldering a butterfly laser diode directly into driver board and large heat sink for stable heat dissipation.
