How do I operate the GXE600 programmable power supplies in Constant Voltage / Constant Current mode?

Posted by Martin on June 24, 2020

The GXE600 series of single output 600W programmable power supplies can operate in the shaded area of the diagram below.

As an example, consider a constant current battery charging application that requires a maximum float voltage of 28V and a constant current charge rate of 15A. The output voltage should be set to 28V, using the output voltage potentiometer, RS-485 interface or an external 0 to 6V source. The current limit point would be set to 15A using the RS-485 interface or external 0-6V source. With the power supply connected to the battery, a 15A charge current would flow as the battery is charged. The battery voltage would gradually rise until it reaches 28V – at which point the charge current will drop to zero.

The GXE600 battery charging characteristics can be programmed and monitored using the downloadable GUI or LabVIEW® – both graphical and manual views are available.

If another battery type needed to be charged, the output float voltage and charge current could be adjusted as required using the RS-485 interface or external voltage sources.
