PIM-Mini-10 Pulsed Current Source — Datasheet For more information: 970.493.1901 or sales@directedenergy.com Document #7675-0008 Rev B1. © Copyright 2019 Directed Energy, Inc. All rights reserved. Precision Pulse Control The Mini -10 is a compact and light weight pulsed current source designed t o drive laser diodes, bars, arrays, or any low -impedance load. The key specifications are output current from 1 A to 10 A, rise and fall times below 8 µs at 10 A, pulse widths from 25 µs to 4000 µs, forward voltage from 0 V to 48 V , and pulse repetition rate from single shot to 5,000 Hz. System Operation The Mini-10 output current may be set with an internal potentiometer or an analog voltage. The pulse width is controlled with the input trigger signal. The system requires two DC voltages for operation, 12 V and compliance voltage equal to 12 V above the laser diode’s forward voltage. Output Cable The laser or load is connected to the Mini-10 with 22 AWG twisted pair cable (included) with a length of 15 cm (6 inches) or less. What is included?
