Constant Current Laser Diode Driver High-power LD Laser Diode Power Supply (LP4250A 42V 50A) LP4250

Constant Current Laser Diode Driver High-power LD Laser Diode Power Supply (LP4250A 42V 50A) LP4250

Description:
It is a high-power laser diode pulse driver power supply. It can operate in pulse current mode. In addition, the current amplitude, repetition rate, and pulse width can be easily configured by the host computer, and the current can be up to 8A/20A/50A (optional). The serial communication interface allows users to configure operating parameters and monitor operating status. This module also provides communication protocols for integration into the users' systems. Small size makes it ideal for use in laser systems.
