4.2.2.1 General information
The EHQ´s are two channel high voltage supplies in a 3U Eurocard Chassis, 8TE wide. The units offers manual control and
operation via analogue I/O
The high voltage supplies special provide high precision output voltage together with very low ripple and noise, even under
full load. Separate 10%-steps hardware switches put voltage and current limits. An INHIBIT input protects connected
sensitive devices. The high voltage output protected against overload and short circuit. The output polarity can be switched
over.
