Spellman SR6PN6

The Spellman SR6PN6 is a 6 kV DC high-voltage power supply module engineered for precision applications requiring stable output and tight regulation. This 6 kW unit delivers up to 1 A at maximum voltage and operates from three-phase 208 VAC ±10%, 50/60 Hz input. Load and line voltage regulation specify 0.005% of full voltage plus 500 mV, while current regulation maintains ±0.05% of full current ±100 µA across load and line variations. Output ripple measures 0.1% peak-to-peak plus 1 Vrms for three-phase operation. The supply features automatic constant voltage/constant current crossover, arc detection with quench and count capabilities, and continuously adjustable voltage and current controls via ten-turn potentiometers with lockable counting dials. Digital voltage and current metering provides 1% accuracy. A “Dead Front” status display indicates up to 14 system operations including regulation status and fault conditions. Temperature coefficient is 100 ppm/°C, with stability of 0.01% per hour after 30 minutes warm-up and 0.02% per 8 hours typical. Operating temperature range is 0°C to +40°C; storage extends to -40°C to +85°C. The unit mounts in a 6U rack configuration (10.5″ H × 19″ W × 19″ D) and includes 10 ft shielded high-voltage output cable. Polarity options include positive, negative, or reversible outputs; reversible polarity for 6 kV models uses a rear panel link. Standard digital interfaces include Ethernet and RS-232. Optional features include adjustable overload trip (AOL), constant power control (CPC), adjustable power trip (APT), floating ground (FG), and selectable slow-start configurations. The SR6PN6 suits scientific instrumentation, semiconductor processing, and medical device applications demanding reliable high-voltage sourcing.
