PCX-6425 Pulsed Current Source
Precision Pulse Control
The PCX-6425 is an air-cooled, high-power current source designed to drive laser diodes, bars, and arrays. The output current can be set from 1 A to 150 A. The load voltage for the PCX-6425 is 0 V to 120 V. The pulse width is adjustable from 100 µs to 5 ms with a pulse repetition rate from single shot to 100 Hz.
System Operation
The PCX-6425 output current and output voltage is set with the encoder on the front of the system. The display allows the user to view all settings on the home screen. These settings are the current output, voltage output, current trip point, and voltage trip point. The pulse width and frequency is controlled with the trigger input at the front panel BNC Gate connection. The PCX-6425 system also has the ability to set the current trip point and the voltage trip point. The user should ensure the instrument is never operated outside of the SOA curves which are at the end of this datasheet.
Complete System Integration
For automated applications, complete control of the instrument is provided through a Serial interface or a USB interface. The connections are on the rear of the instrument.

Notes
1Operation of instrument outside of the listed load voltage and maximum power limits can cause permanent damage to the instrument and/or load. Please see the SOA graphs in the manual for more information.
Warranty: One year parts and labor on defects in materials and workmanship.
The PCX-6425 current source meets or exceeds these specifications.
All specifications are measured using the standard included output cable and a HPL-2400 (low-inductance, high-power resistive load). Load not included.
Specifications subject to change without notice.
Safe Operating Area Graphs
IMPORTANT: Do not operate the instrument outside of the Safe Operating Area! Although the PCX-6425’s external triggering system allows it to operate outside the Safe Operating Area, such operation will result in permanent damage to the PCX-6425, the laser diode, or both.
