Measuring Current on the PCO-7114 Series

Watch the Video Many inquiries have been made about measuring the output current on the PCO-7114 pulsed laser diode driver modules. In the following article the proper current measurement technique will be explained. In this demonstration the PCO-7114-50-4 will be used and will be tested into a shorted load. The current monitor cable is a […]

Accurately Measuring Pulse Current on the PCO-6131 and PCO-6141

Watch the Video To measure the output pulse current to the load from your PCO 6131 or the PCO-6141, you will need a Current Monitor assembly. The current monitor contains a current-to-voltage resistor (CVR), also known as a current sense resistor.  The use of this accessory board eliminates the uncertainty of the exact current and […]

How do I set the PCO-7810’s pulse frequency (pulse repetition rate)?

A trigger source sets the pulse frequency. Either the PCO-7810’s internal trigger source, or an external source, can be used. (The width of the pulse is fixed and varies with the model.) Due to power dissipation limits, each model has a maximum specified pulse frequency. Specifically: The PCO-7810-40-4 can output pulses up to 40 A at rates up to 200 kHz, but it requires forced air cooling above 100 kHz. The […]

How do I set the PCO-6131/PCO-6141 output current?

The output current is controlled by a small DC voltage that can be supplied by either an on-board source (Local Control mode) or by an external source (External Control mode). There are four items associated with setting the output current: I SET three-pin header CURRENT SET pot Current Setpoint input (pin 4 of J2) Output […]
