150A 40V QUASI-CW LASER DIODE DRIVER/PULSED CURRENT SOURCE

The PCX-6220 is an air-cooled, high power switch-mode pulsed current source designed to drive diode lasers, bars and arrays. It delivers current pulses variable from 1A to 150A, pulse widths variable from <50µs to 20ms, and pulse repetition frequencies variable from single shot to 5KHz at duty cycles up to 50%.
A microprocessor-controlled front-panel and RS-232/IEEE-488 interface provide individual control of each electronic function, while the backlit alphanumeric LCD display provides immediate visual confirmation of all operating parameters, including output current amplitude, pulse width, repetition frequency, duty cycle, and error and fault messages. In addition to stand-alone operation, the PCX-6220 can be externally triggered.
The output voltage, output current and average output power are continuously displayed on the front panel display. Instrumentquality analog current and voltage monitors and a synchronization output are also provided for real-time monitoring of the current and voltage to the laser diode.
