COMPACT HIGH VOLTAGE POWER SUPPLY C4900 SERIES 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. FEATURES ● Low Ripple / Noise ● Very compact and lightweight ● High stability ● Low power consumption ● Quick response ● Ample protective functions SPECIFICATIONS Parameter C4900 C4900-01 C4900-50 C4900-51 Unit Input Voltage Range +12 ± 0.5 V +15 ± 1 +12 ± 0.5 +15 ± 1 with no load Typ. 15 14 15 14 Input Current A mA with full load Typ. 95 90 95 90 0 to +1250 Variable Output Voltage Range V 0 to -1250 +200 to +1250 Specification Guaranteed Output Voltage Range V -200 to -1250 Max.
