2018 was quite a year for us here at Directed Energy (formerly IXYS Colorado and, more formerly than that… Directed Energy)! You may know that IXYS was acquired by Littelfuse in January of 2018. During the integration of IXYS technologies into Littelfuse, I had the opportunity to purchase Directed Energy and the associated laser diode…

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…

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…

Watch the Video 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…

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…
