IXYS adds flexibility to high power laser diode driver and current source

The PCX-7500-EX is an air-cooled, benchtop current source designed to drive laser diodes, bars and arrays at up to 450 A of current and 110 V maximum forward voltage, with additional flexibility by using external power supplies. While the previous PCX-7500 current source offers various models to tailor the driver to the diode load depending upon its internal power supply, the PCX-7500-EX uses an external DC power supply to source the laser diode forward voltage. By matching the DC supply to the diode’s forward voltage, a single PCX-7500-EX current source can power a variety of laser diodes at full output current, from a single device to a 110 V diode array.

Pulse widths are adjustable from 30 to 5,000 µs with rise and fall times under 15 µs and frequencies up to 10 kHz and the source is aimed at research, laboratory, scientific and industrial applications.

It uses USB, Ethernet or RS-232 communication for engineers to easily develop automated testing and characterization configurations that can be stored in the instrument’s on-board memory. It can also be operated through its intuitive front panel controls. The colour LCD provides immediate visual confirmation of all operating parameters.

“The PCX-7500-EX builds on the proven design of the PCX-7500 to provide the user with even greater operating and design flexibility,” said Stephen Krausse, General Manager of IXYS Colorado. “This driver leverages decades of IXYS Colorado designs and the power integration experience of our parent company, IXYS Corporation, with its advanced power MOS device technology, to deliver one of the highest power, most user-friendly drivers available on the market today.”

The PCX-7500-EX is available directly from IXYS Colorado (also known as Directed Energy, Inc. or DEI)
