Programmable Switching DC Power Supply, PSW 80-13.5, GW Instek

The PSW 80-13.5 is a single-output multi-range programmable switching DC power supply covering a power range up to 1080W. The multi-range feature allows the flexible and efficient configuration of voltage and current within the rated power range. The CV/CC priority selection of the PSW is a very useful feature for DUT protection. The conventional power supply normally operates under CV mode when the power 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. Taking the I-V curve verification of LED as an example, it becomes a very challenging task to perform this measurement using a conventional power supply. With LED connected to a power supply under CV mode as the initial setting, when the power output is turned on and the voltage rises to the LED forward voltage, the current will suddenly peak up and exceed the preset value of current limit. Upon detecting this high current, the power supply starts the transition from CV mode to CC mode.
