Analog Laser Drivers
DRV-CV-PS200 converts a power supply from PBA series by Cosel to a laser driver. It is designed for laser pulses >5 ms. Its configuration is far more compact than a conventional laser diode driver since it eliminates the need for large capacitors, and associated electronics, increasing reliability and reducing cost. DRV-CV-PS200 includes an internal security actuator which protects the laser diode against a possible power supply failure or a connection error.
