IXYS Colorado Introduces PCX-7450 High Powered Pulsed Laser Diode Driver

IXYS Corporation (NASDAQ:IXYS), a leader in power semiconductors for power conversion and motion control applications, announced today the introduction of the PCX-7450 by its Colorado division. The PCX-7450 is an air-cooled, high power pulsed current source designed to drive diode lasers, bars and arrays. It delivers current pulses variable from 20A to 150A, pulse widths from 10 micro s to 5 micro s, rise and fall times of 5 micro s to 1ms, and pulse repetition frequencies variable from single shot to 5 KHz with duty cycles limited by total power dissipation.

Pulse rise and fall times can be set independently from the front panel. Each can be independently adjusted in the range is 5 micro s to 1ms.

A microprocessor controlled front panel provides individual control of each electronic function, while the backlit display provides immediate visual confirmation of all operating parameters, including output current set point and amplitude, pulse width, repetition frequency, duty cycle, and error and fault messages. The front panel controls allow the user to set pulse width and frequency independently, or to set frequency and duty cycle, which then sets the pulse width accordingly. The front panel display monitors both the set points and the actual current delivered to the diode.

Analog current and voltage monitors and a synchronization output are also provided for monitoring of the current and voltage to the laser diode. In addition to stand alone operation, the PCX-7450 can be externally triggered and is equipped with an RS232 interface - standard.

The PCX-7450 is designed for use in scientific, industrial and commercial applications such as high power laser and diode characterization, automated testing and scientific experimentation.
