SPECIFICATIONS
FEATURES
The C4900 series is an on-board type high voltage power
supply, 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.
The C4900 and -01 are designed for negative output, while
the C4900-50 and -51 have positive output.
