Spellman RHR5P100

The Spellman RHR5P100 is a high-reliability, compact DC high-voltage power supply engineered for precision applications requiring stable outputs and minimal ripple. This fan-cooled unit delivers continuously adjustable voltage from zero to maximum rated output with excellent line and load regulation, rapid transient recovery, and integrated protection across overload, short-circuit, and arc-over conditions. Front-panel ten-turn potentiometer control combines with remote voltage control (0–6 VDC programming) and optional remote resistance control for flexible system integration. The supply includes single-range voltmeter and ammeter metering (2% accuracy), floating ground isolation up to 80 V, and remote monitor terminals.
