About this file

This is a technical specifications document for a high voltage power supply requisition (WS482087) issued by the Department of Energy Office of Science. The supply must deliver dual output voltages of ±80 kV at 0.3 mA output current with 24 W power capacity. The unit shall weigh approximately 35 kg with overall dimensions of 19.0 inches width, 8.74 inches height, and 21.65 inches depth, and must operate on 115 VAC ±10%, single-phase, 50/60 Hz input power.

The equipment must meet strict performance standards including 10 ppm RMS ripple, 50 ppm/hour stability, 50 ppm/°C temperature coefficient, and 10 ppm line and load regulation specifications. The power supply shall include comprehensive protection features (overvoltage, overcurrent, short-circuit, and arc protection), remote voltage control via 0-10 VDC with output voltage and current monitoring capabilities, and remote ON/OFF control with interlock functionality. The unit must incorporate remote digital control and monitoring via USB, LAN, RS-232C, RS-485, or GPIB with an integrated controller and interface. Operating conditions are 0 to +45°C temperature range and 20-80% relative humidity (non-condensing). Respondents must provide quotes that include pricing, country of origin, lead time, UEI number, and factory testing data with required factory test documentation.
