Installation and Operating Manual –Series 205B Page 4
SECTION 1 - GENERAL INFORMATION
1.1
PURPOSE OF THE EQUIPMENT
The Series 205B 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 205B is a family of 19” rack-mountable power supplies with output voltages up to 50
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 rear panel features a HV output
connector, a connector for remote analog programming and output voltage and output current
monitoring, the output polarity switch, 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
SPECIFICATIONS
For the Series 205B detailed specifications, refer to the Specifications section.
1.4
OPTIONS (OEM APPLICATIONS ONLY)
Isolated Floating Output
Units can be provided with the output capable of floating up to
±
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.
