THIS POWER SUPPLY GENERATES VOLTAGES
THAT ARE DANGEROUS AND MAY BE FATAL.
OBSERVE EXTREME CAUTION WHEN
WORKING WITH HIGH VOLTAGE.
6.1 Periodic Servicing
Approximately once a year (more often in high dust
environments), disconnect the power to the unit, wait 5
minutes and remove the top cover. Use compressed air to
blow dust out of the inside of the unit. Be sure that the
fan is not obstructed and spins freely. The fan has sealed
bearings and does not need lubrication. Be sure to
replace the top cover before operating for proper cooling.
6.2 Performance Test
HIGH VOLTAGE IS DANGEROUS.
ONLY QUALIFIED PERSONNEL SHOULD
PERFORM THESE TESTS .
High voltage test procedures are described in Bulletin
STP-783,
Standard Test Procedures for High Voltage
Power Supplies . Copies can be obtained from the
Spellman website. Test equipment, including an
oscilloscope, a high impedance voltmeter, and a high
voltage divider such as the Spellman HVD-200 or HVD-
400, is needed for performance tests. All test components
must be rated for operating voltage.
6.3 High Voltage Dividers
High voltage dividers for precise measurements of output
voltage with accuracy up to 0.1% are available. An
HVD-100 is used for voltages up to 100kV, HVD-200
measures up to 200kV and the HVD-400 measured up to
400kV. The Spellman HVD Series is designed for use
with differential voltmeters or high impedance digital
voltmeters. The high input impedance is ideal for
measuring high voltage low current sources, which would
be overloaded by traditional lower impedance dividers.
