The GW Instek PSW 40-27 is a programmable lab power supply that is ideal for testing, for example, a Device Under Test (DUT). The lab power supply has Constant Voltage- (CV) and Constant Current- (CC) modes, which are useful for the protection of DUT’s particularly in the battery and LED industry.The power supply has active cooling and an analog control, with an adjustable slew rate. Another useful feature of the PSW series is that it is capable of series operation (2 units) or parallel operation (up to 3 units), to increase the voltage or current respectively.
The Over Voltage and Over Current Protections have adjustable levels, making them very suitable for the protection of DUT’s.
