PCM-7140-200

5 A to 200 A, 25 µs to 13 ms OEM Laser Diode Driver Module

Categories: , ,

Product Description

The PCM-7140-200 is a compact pulsed and QCW current source designed to drive laser diodes, bars, arrays, or any low impedance load. The key specifications are output current from 5 A to 200 A, rise and fall times below 10 μs at 200 A, pulse widths from 25 μs to 13 ms, pulse repetition rates from single shot to 5500 Hz, and forward voltage from 0 V to 55 V.

The PCM-7140 output current may be set with an internal potentiometer or an external analog voltage. The pulse width is controlled with an external trigger source.

The system requires two DC supplies for operation: 12 V for housekeeping and a voltage ≤ 20 V above the laser diode’s forward voltage.

The laser or load is connected to the PCM-7140 with a 100 cm length of 18 AWG twisted pair cable (included). This same cable has the DC input connection from the high voltage power supply.

The PCM-7140 module is liquid cooled with a liquid temperature of 11 °C to 22 °C with a flow rate of 6 liters per minute. The connection type is 3/8” tubing.
