GW Instek SPS-Series Switching DC Power Supply - GW Instek SPS-1230, The GW Instek  SPS-Series are a single output, 360W, switching DC power supply. OVP protects the SPS-Series and their load from unexpected conditions. High regulation is maintained at 0.01%. Remote sensing adds extra level of precision by compensating cable losses between loads. Turning the output On/Off from external device is available through remote control terminals. The SPS-Series are an ideal solution for power-efficient bench-top or portable applications requiring high regulation. GW Instek SPS-1230 Switching DC Power Supply
