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.

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.

SES-CAMM Compatible

This unit can also be connected to PC through an interface module SES-CAMM to record voltage values.SES-CAMM is computer aided module for connecting multiple subunits of experiments, such as Two Probe Setup,to same interface on a computer.This feature is particulary useful in making this model compatible with computerized versions of complete experiments from our company.


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.
