1.1 PURPOSE OF THE EQUIPMENT
The Series 230 is a family of regulated precision
laboratory high voltage power supplies. They
provide exceptional performance in critical
applications such as nuclear and electro-optical
instrumentation, precision CRT and electron
beam applications.
1.2 DESCRIPTION
The Series 230 is a family of compact bench top
power supplies with output voltages up to 30
kV. The units consist of a DC power supply that
converts the AC line power to a low DC voltage
and a DC to DC converter that generates the
high DC output voltage. Low voltage electronic
solid-state circuitry is mounted on the PCB100,
and the high voltage assembly is fully
encapsulated for reliable, arc-free, operation.
These stable, low noise high voltage power
supplies feature front panel digital voltage and
current metering, and calibrated direct-reading
front panel controls. The high voltage output is
also obtainable from the front panel. The rear
panel features a connector for remote analog
programming and output voltage and output
current monitoring, line power plug, fuse,
and AC voltage selection switch. All units have
arc and short circuit protection for safe, reliable,
and arc-free operation. Although primarily
designed for rack mounting, the unit may also be
used in benchtop applications.
1.3 OPTIONS
Isolated Floating Output
Units can be provided with the output capable of
floating up to
r
2kV from ground. All controls,
programming and monitoring functions operate
normally, referenced to ground. The high
voltage output polarity, with respect to the
floating input terminal is reversible.
1.4 SAFETY TERMS

WARNING
used in this manual explains
dangers that could result in personal injury or
death.
The
CAUTION
used in this manual explains
hazards that could damage the instrument.
SECTION 2 OPERATION
2.1 INSTALLATION
WARNING!
This unit produces hazardous
voltage. Do not apply line voltage input unless
adequate ground is connected to the unit and
the high voltage output has been properly
connected.
2.2 FRONT PANEL CONTROLS AND
DISPLAYS
Output Connector:
The HV output connector on the 1kV through
5kV models mate with a shielded mating
connector supplied with each unit. Refer to the
specifications on page 12 to identify the mating
connector. Assembly procedures for mating
connectors are given at the end of this manual.
On 10kV through 30kV models, an unshielded,
preassembled high voltage cable connected to
the appropriate connector is provided with each
unit. Only the proper mating connector should
be used with the indicated power supply and the
power supply should NEVER be energized
without a mating connector and suitable load
connected.
Power Switch:
A rocker switch turns the line power on or off to
the entire instrument. The display panel will be
lit when line power is applied to the unit.
Output Meter:
The digital output meter can display the output
current or the output voltage. A switch below
the meter allows the operator to select which
output parameter to monitor. The accuracy of
the meter is given in the specification (see page
12).
Polarity Indicator:
An LED on the front panel display indicates the
polarity of the output. The appropriate LED is
lit as soon as line power is applied regardless of
whether high voltage output is enabled or
disabled. To change the polarity setting, see
paragraph 2.4.
