UltraVolt’s
HV Rack
®
system can provide up to 4 channels of high-voltage power. The channels are configured
at the factory to customer requirements. During operation, the output voltage and current for each channel can
be individually set and monitored either through adjustment of the front-panel controls or remotely. Each
channel also has an
HV ON
switch, which enables or disables the output. Voltage and current can be preset
prior to enabling the output.
In addition to the individual channel controls, there are a
Front Panel AC Power Switch
that will disconnect the
AC line and a remote indicator to show when the rear panel
Remote Control Selector
DIP Switch
is in the
‘remote’ position. ‘Local’ setting enables all front-panel controls; ‘remote’ setting transfers all operation and
programming functions to the rear-panel-mounted 37-pin ‘D’ connector.
