Model SF-9586
KILOVOLT POWER SUPPLY

Introduction

The PASCO scientific Model SF-9586 Kilovolt Power
Supply provides regulated DC power from 0 to 6 kilo-
volts. The 6 kilovolt output is center tapped, providing
outputs of 0 to +/-3 kilovolts. In addition, a pair of output
jacks provides 6.3 volts of AC power, which is commonly
used as filament power in electron tube experiments.
IMPORTANT:
The 6.3 VAC output is unregulated. If you are
using it to heat the filament in a vacuum tube, we
recommend that you use a current limiting resistor
(1-2 Ω, variable) in series. Measure the voltage at
the filament and adjust the resistance to get the re-
quired voltage.
For an accurate meter reading, always use the
left and right output jacks (6 kV). Use the middle
jack only when your application requires a center-
tapped voltage. (The center tap will be the mid-
point of the output voltage only if equal currents
are drawn from the ±3 kV output jacks.)

To Use the Power Supply:

Plug the power cord into a well-grounded 107-128 VAC,
60 Hz or 198-242 VAC, 50 Hz outlet. (See label on
rear of unit).
Connect the appropriate output terminals of the power
supply to the circuit. (Connecting wires are not pro-
vided with the supply.)
Turn the HIGH VOLTAGE ADJUST knob fully
counterclockwise.
Flip the ON/OFF switch on the front panel to ON.
The switch will light to show that the power is on.
Turn the HIGH VOLTAGE ADJUST knob to obtain
the desired output. The meter will show the voltage
between the 6 KV output terminals.
CAUTION!—HIGH VOLTAGE
The power supply uses two 390 KΩ resistors
which limit the output current to approximately
3mA. Nevertheless:
* 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.
