Laser diode driver LDD-1321 is a high-precision, low-power current source optimized for CW. With a newly developed power stage for lower currents, still with the proven and stable MeCom interface protocol and free of charge PC software for easy integration into your system.


Also interesting! The LDD-1321 has connections for a plug-on TEC Controller board. This board features a bidirectional current driver, which enables the TEC Controller functionality of the whole device. Please contact our sales team for further information or prototype testing.

Detailed Description

The LDD-1321 is a current driver designed to precision-drive low-current laser diodes or other loads in continuous wave applications.

It offers various safety features, including two inputs for laser diode temperature monitoring.
The device can be fully digitally controlled, the firmware can be upgraded, and various digital and analog interfaces are available.
