GW Instek PSW 250-9 250 Volt 9 Amp DC Power Supply

The PSW 250-9 is a single output programmable switching DC power supply that covers a power range up to 720W. A very useful feature for DUT protection are the CV and CC selections. While in CV mode the power output is turned on and the voltage rises to the LED forward voltage. Then the current will peak up and exceed the preset value of current limit. To limit the current spike occurred at the threshold voltage and protect the DUT from the inrush current damage the PSW-Series is able to run under CC priority.

Another way the PSW prevents DUT damage is with the OVP and OCP protections. Both the OVP and OCP can be selected, with the default level set at 110%, of the rated voltage / current of the power supply. The PSW has available at the rear panel the LabView driver. The driver is for external control of the power On/Off and the external monitoring of the power output voltage and current.
