PCX-7401 Pulsed Precision Current Source — Datasheet For more information contact us: 970.493.1901 or sales@directedenergy.com Document #7675-0003 Rev D1. © Copyright 2018 Directed Energy, Inc. All rights reserved. Precision Pulse Control The PCX -7401 offers the capability of providing both pulsed and bias outputs. A modern internal trigger source is capable of two modes of operation: duty cycle and single shot. External trigger is available for additional flexibility. Low Inductance Output Cable Connection to the laser diode is made t hrough an innovative low-inductance stripline cable, designed to preserve the fidelity of high- speed current pulses. The output connector is interlocked s o that the PCX -7401 is disabled when the cable is removed. Output Protection The PCX-7401 features advanced circuitry to protect both the laser diode and instrument. At turn on, and at any time the output is not enabled, the PCX -7401’s output is electronically shorted to ground, ensuring that no current flows through the laser diode. Safety features of the instrument include a separate output enable key switch, an output cable safety interlock, and an external enable control signal. Ease of Setup and Operation The PCX-7401 may be operated through the intuitive front panel controls. The color LCD provides immediate visual confirmation of all operating parameters. Store and Recall User Settings All system configurations may be stored and recalled in the internal non-volatile memory. Complete System Integration Automated applications can utilize RS-232, USB , or Ethernet computer interfaces.
