DESCRIPTION
l-10 Output power is available vie ,mo WG-931/U
connectors mounted on the front panel of the supply, Mating
cornwctors (UC=-932/U) are supplied
with the unit. The output terminals are isolated
from the chassis and either the positive or the negative terminal tnay be connected to the chassis by
shorting the cer~ter ptn tQ the case of the epplica<
ble VG-931/U connector,
or by grounding e wire
from the connector to the chassis,
The p0Wer *UPply is insulated to permit operation up to 1,000
volts dc off ground, i. e. the maximum potential
between either output terminal end ground shall not
exceed 4KVdc,
l-2
This instrument (Figure 1-l) is an all semiconductor high voltage supply suitable for either
bench or relay rack opwation.
It is a compact,
well-regulated,
Constant Voltage/Current
Limited
supply that will furnish 3, 000 volts et 6 m~lliampS
or carp be adjustEd throughout the output voltage
range, It is designed for *ppIicattons
rwuiring
extreme EtabilIty,
regulation,
and insensitivity
to
ambient temperature variations.
l-3
This supply utilizes a series regulated
“piggy-back”
circuit technique.that
consists of
placing e well-regulated
low voltage power supply
in series with e lees well-regulated
supply having
a greeter vo!tage capa.bility.
The well-regulated
“piggy-back”
supply continuously
com!x”setee
for
any ripple, load regulation,
or Iine regulation deficiencies
of the main power source end adjusts
the voltage across its series regulator so that the
total output voltage remains constant despite disturbances in the main voltage source.

current or voltage exceeds these preset levels.
Detailed characteristics
of the output current iimittng are given in Paragraph 3-5.
Option No*
l-6
The powor supply is protected from .+everse
voltage (positive voltage applied to negative terminal) by en internal protection diode thet shunts
current across the output terminal6 when this condition exists, clamping tha reveree voltage.
Protection from rewrse current (current forced into
the power $upply in the direction oppoiite to the
output current) must be provided by prebading
the
power supply (Paragraph 3-151, The power euppIy
