The Keithley 241 Regulated High Voltage Power Supply is rated 1000 V @ 20
milliamps. Applications include calibration of meters, transducers and power
supplies and the testing of leakage resistance of insulation, capacitors and
diodes. It can also be used as a secondary laboratory standard, dc standard for
ac transfer measurements, voltage reference for analog computers and excitation
potential source for photocells and ion chambers.
