High Voltage Power Supply
Power supply, EHT-11 principle of operation is entirely different from
conventional supplies, and thereby eliminating many drawbacks; bulky
high voltage transformer, need of high voltage components and excessive
heating of components etc., associated with them. This power supply
consists of a stable power oscillator whose output is controlled by an input
signal. The output of this oscillator is boosted with the help of a step-up
transformer and then rectified and filtered. A portion of this output is
compared with a high stability, temperature compensated reference and
the error signal is used in the feedback path to control the oscillator’s output.
There is a built-in protection against accidental overloading.
EHT-11
l
Continuously variable
l
Electronically regulated
l
Fully solid state circuit
l
Low power consumption
Applications
EHT-11 is designed to meet the
power requirements of a broad
range of radiation detectors: G.M.
Counters, lonization Chambers,
Scintillation Detectors, Photomultiplier Tubes and any application where a high voltage source
with high degree of regulation and
stability is required.
For high reliability, compactness and ruggedness, integrated circuits are
extensively used along with a few discrete silicon devices. The
components are mounted in a glass epoxy printed circuit card.
