The Kepco DPS-12.5-6M is a 75 W single-output programmable DC power supply for benchtop use or system integration. It delivers 0-12.5 V DC at 0-6 A with automatic crossover between voltage and current regulation modes. The front-panel keypad controls voltage, current limit, range, and OVP settings with separate LED displays for voltage and current readout. RS-232 connectivity via KOIB protocol enables remote control from BASIC or standard programming languages. Remote sensing compensates for up to 0.5 V drop per output lead. Fast voltage recovery under step load current occurs in less than 50 microseconds, with no overshoot above 25% voltage setting. The unit operates from single-phase AC mains without range selection and provides 500 V isolation to chassis.
