Introduction
The PASCO scientific Model SF-9585A High Voltage
Power Supply provides regulated DC power up to 50 mA
in two voltage ranges: 0 to -50 and 0 to 500 volts. The
outputs for the two ranges are independently adjustable,
though a single terminal is used as the positive terminal
for the 50 volt output and as the negative terminal for the
500 volt output. The meters read voltage and current in
either range.
In addition, a separate filament voltage supply provides
unregulated AC power up to 3 amperes at 2 to 7 volts.
Voltage selection for the filament supply is simply a mat-
ter of turning the voltage adjustment knob on the front
panel to the desired voltage.
To Use the Power Supply:
➤ CAUTION—HIGH VOLTAGE:
• Play it safe: Always work with a partner.
• Wear rubber soled shoes.
• Work with one hand only. Keep the other hand in
your pocket or behind your back.
➀
Plug the power cord into a well-grounded 115
VAC, 60 Hz or 230 VAC, 50 Hz outlet. (See label
on rear of unit).
➁ Connect the appropriate output terminals of the power
supply to the circuit. (Connecting wires are not pro-
vided with the supply.) The -50 and 500 volt ranges,
as well as the filament supply, may all be used simul-
taneously.
➂ Turn the 50 VOLT ADJUST knob and the 500 VOLT
ADJUST knob fully counterclockwise.
