3B Scientific U33000-230 DC Power Supply, 0-500 VDC

Low voltage power supply with four outputs primarily intended to simultaneously supply power for the Teltron line of electron tubes and Helmholtz Coils, with four independent, adjustable DC voltages. The DC voltages are stabilized, regulated, floating, and galvanically isolated from one another, in addition to being short circuit proof and secure from external voltages. 500 volts output: Voltage: 0 - 500 volts DC, maximum 50 milliampere, Stability at full load: <=0.01 percent +/-100 megavolts, Residual ripple: <=20 megavolts. 50 volts output: Voltage: 0 - 50 volts DC, max. 50 milliampere, Stability at full load: <=0.1 percent +/-30 megavolts, Residual ripple: <=50 megavolts. 12 volts output: Voltage: 0 - -12 volts DC, max. 4 ampere, Residual ripple: <=0.1 percent +/-30 megavolts, Overload protection: Thermal cut-out, Displays: Analogue, class 2, Connections: 4mm safety sockets, Power consumption: 50 VA. 8 volts output: Voltage: 0 - 8 volts DC, max. 3 ampere, Residual ripple: <=0.1 percent +/-30 megavolts, Overload protection: Thermal cut-out. 230 Volts.
