6 MAINTENANCE
This section describes periodic servicing
and performance testing procedures.
WARNING
:
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 and remove the top
cover. Use compressed air to blow dust
out of the inside of the unit. Avoid
touching or handling the high voltage
assembly. Be sure that the fans are not
obstructed and spin freely. The fans have
sealed bearings and do not need
lubrication. Be sure to replace the top
cover before operating for proper
cooling.
6.2 PERFORMANCE TEST
WARNING:
HIGH VOLTAGE IS DANGEROUS.
Only qualified personnel should perform
these tests.
High voltage test procedures are
described in Spellman Bulletin STP-783,
Standard Test Procedures for High
Voltage Power Supplies. Copies can be
obtained from the Spellman Customer
Service Department. Test equipment,
including an oscilloscope, a high
impedance voltmeter, and a high voltage
divider such as the Spellman HVD-100
or HVD-200, is needed for performance
tests. All test components must be rated
for operating voltage.
6.3 HIGH VOLTAGE
DIVIDERS
High voltage dividers for precise
measurement of output voltage with an
accuracy up to 0.1% are available from
Spellman. The HVD-100 is used for
voltages up to 100kV. The HVD-200
measures up to 200kV. The Spellman
divider 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.
