IG Series

TYPE IG005, IG010 & IG020

These power supplies are intended to power ion guns at voltages up to +20 kV. They include an isolated heater supply joined to the anode together with a separately controllable focus supply. They are based on the standard HP series (data sheet refers) with the frequency of the additional heater supply synchronised to the two high voltage oscillators.

All outputs are controllable by 0 to +10V signals & monitor signals are provided for anode voltage, focus voltage, heater current & anode current. They can be supplied with additional voltage outputs tapped off the main anode supply (to order).
