FORT COLLINS, Colo., 21 June 2008.IXYS Corp., maker of power semiconductors for power conversion and motion control applications, introduced 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 1 ms, and pulse repetition frequencies variable from single shot to 5 KHz with duty cycles limited by total power dissipation.
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.
