The GW Instek GW-PSU-Series is a single output programmable switching DC power supply covering a power range up to 1520W. This series of products include five models with the combination from 6V to 60V rated voltages. As the PSU-Series can be connected in series for maximum 2 units or in parallel for maximum 4 units, the capability of connecting multiple PSU-Series units for higher voltage or higher current output provides a broad coverage of applications.

The C.V. / C.C. priority selection of the GW Instek GW-PSU 40-38 is a very useful feature for DUT protection. The conventional power supply normally operates under C.V. mode when the power supply output is turned on. This could bring a high 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 on stage, the GW-PSU 40-38 is able to run under C.C. priority to limit the current spike occurred at the threshold voltage and therefore protects DUT from the inrush current damage.

The OVP and OCP protection can prevent the DUT damage, Both OVP and OCP levels can be selected the range of minimum setting to 110%, with the default level set at 110%, of the rated voltage/current of the power supply. The GW Instek GW-PSU 40-38 provides USB Host/ Device, LAN, RS-232 with RS-485 and Analog Control Interfaces as standard. The Analog Control Interface is also available at the rear panel for external control of the power On/Off and the external monitoring of power output voltage and current.

The adjustable slew rate of the GW Instek GW-PSU 40-38 allows users to set, for either output voltage or output current, a specific rise time from low to high level transition, and a specific fall time from high to low level transition. This facilitates the characteristic verification of a DUT during voltage or current level changes with controllable slew rates. Most manufacturing tests of lighting devices or large capacitances during power output on are associated with the occurrence of high surge current, which can greatly reduce the life time of the DUT. To prevent inrush current from damaging current intensive devices, a smooth and slow voltage transition during power On-Off can significantly reduce the spike current and protect the device from high current damage.
