Magnavolt Series HCB

Description

High Voltage bipolar output, + 1.125kV to  + 20kV, 1.4W to 200W high precision

Features

– Light-weight
– In units with 6,5 kV and higher the HV-components are moulded in (removable) silicon resin
– Unlimited operation with rated current in a short-circuit condition
– Unlimited operation with nominal power
– Voltage regulation and current limitation with automatic, sharp transition
– Control mode indicated by LED
– Voltage adjustment with 10-turn potentiometers with precision scale; the adjusting knob can be locked
– 4½ digit DVM for voltage and current
– 4- quadrant operation possible (for passive loads)
– Suitable for capacitive and resistive loads

Function

– Bipolar HV power supplies consist of 2 switch-mode controlled HV sources which are connected to the output. In principle, the rectified line voltage in each source drives a square wave generator of fixed frequency, whose AC voltage is transformed, rectified and filtered, producing the positive or negative output voltage. For regulation, the square wave voltage is pulse width modulated. The operation is contra-moving, and the output can be adjusted with continuous zero crossing.
