1-l DESCRIPTION
l-2 This instrument (Figure 1-l) is an all semi-
conductor 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.
l-4 OVERLOAD PROTECTION
1-S The voltage thumbwheel witches select the
constant voltage level: an internal potentiometer
selecte the current limit level. The
supply
will
automatically crossover frbm conetant voltage to
currant limit operatim and vice versa if the output
current or voltage exceeds these
preset levels.
Detailed characteristics of the output current iimittng are given in Paragraph 3-5.
l-6 The powor supply is protected from .+everse
voltage (positive voltage applied to negative ter-
minal) 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
cannot accept reverse current without damage.
l-7
COOLlNG
l-10 Output power is available vie ,mo WG-931/U
connectors mounted on the front panel of the sup-
ply,
Mating
with the unit.
cornwctors (UC=-932/U) are supplied
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
*UP-
ply 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,
