Kenwood PS36-20

The Kenwood PS36-20 is a regulated DC power supply delivering 0–36 VDC at 0–20 ADC with up to 720 W output power. This stand-alone unit combines constant voltage and constant current operation modes, making it suitable for laboratory testing, amateur radio, and general electronic development. A temperature-sensitive fan minimizes acoustic noise under light-load conditions, while comprehensive protection circuits—including output over-voltage, over-current, over-heat, and input abnormality detection—safeguard connected equipment. The unit accepts 100 V ±10%, 120 V, 220 V, or 240 V AC input (internally switchable, maximum 250 VAC) at 50/60 Hz and consumes 10 W standby power.
