GW Instek PSU-Series Programmable Switching DC Power Supply

The Constant Current/Constant Voltage (C.V. / C.C.) priority selection of the GW Instek PSU-Series is a very useful feature for Device Under Test (DUT) protection. The conventional power supply normally operates under C.V. mode when the power supply is turned on. This could bring inrush current to the capacitive load or current-intensive load at the power output ON stage. Though the current becomes stable after the C.C. mode is activated, the current spike occurred at the C.V. and C.C. crossover point may possibly damage the DUT. At the power output stage, the PSU-Series is able to run under C.C. priority to limit the current spike occurred at the threshold voltage and therefore protects the DUT from the inrush current damage.

The Over Voltage Protection and Over Current Protection (OVP & OCP) protections can prevent the DUT damage. Both OVP and OCP levels can be selected in the range of 10% to 110%, with the default level set at 110%, of the rated voltage / current of the power supply. The PSU-Series provides USB Host / Device, LAN, RS-232C with RS-485 and Analog Control Interfaces as standard. The LabView driver is available at the rear panel for external control of the power On / Off and the external monitoring of the output voltages and current.
