17 Feb 2010 The PCX-7451 is an air-cooled, high power pulsed current source designed to drive laser diodes, bars and arrays. It delivers current pulses variable from 20A to 225A. Selectable pulse widths can vary from 15μS to 5mS, with rise times and fall times of 5μS to 1mS, and pulse repetition frequencies are variable from single shot to 5 KHz with duty cycles limited by total power dissipation.
A microprocessor-controlled front panel and RS-232 interface provide individual control of each function, while the backlit display provides immediate visual
confirmation of all set point operating parameters including duty cycle, current limits, voltage limits and fault messages. The front panel controls allow the user to
set pulse width and frequency independently, or set frequency and duty cycle, which then sets pulse width accordingly. |
