Compact High Voltage Power Supply Units

C4900 Series

The C4900 series is an on-board type high voltage power

supply unit, with a design that aims at providing both

“compactness and high performance”.

The newly developed circuit achieves high performance

and low power consumption. The C4900 series in addition

provides enhanced protective functions yet is offered at

lower costs.
