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 de-

ficiencies of the main power source end adjusts

the voltage across its series regulator so that the

total output voltage remains constant despite dis-

turbances 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 iim-

ittng 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 con-

dition exists, clamping tha reveree voltage. Pro-

tection 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

cornwctors (UC=-932/U) are supplied

with the unit.

The output terminals are isolated

from the chassis and either the positive or the neg-

ative 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,
