DC/DC Converters

Ultra-compact, Adjustable Output; Input Voltage 11.5 – 13.5 VDC, 22.5 – 26.5 VDC; Output Voltage 300 V, 600 V, 1 kV, 2 kV The HV4479 series is a direct replacement and pin-to-pin compatible to the standard 4479 converters. The micro-size and lightweight converters feature very low noise and low drift and are available as 12V and 24V models. The HV4479 has voltage and current monitors, a low temperature coefficient and is protected against arc and short-circuit. It is available with output voltages of 300 V, 600V, 1kV and 2kV. Key features: Very low noise – very low drift Vout: 300V, 600V, 1kV or 2kV models Vin: 12 or 24V options Polarity: fixed, negative or positive options Remote voltage programming or embedded potentiometer Voltage & current monitors Output overshoot free, limited slew rate Applications: Photomultiplier tubes and avalanche photo diodes

Compact Size; Input Voltage 4.5 to 15.5 VDC; Output Voltage 200 to 500 VDC, programmable from 0 to 100%; Output Power 100 mW The highly compact SDS's APD series is specially designed to meet the high voltage power requirements of scientific instrumentation used in the industrial, medical and military sectors. These modules provide access to voltages of up to 500 VDC in instruments where space is an important factor in order to achieve greater quantum efficiency and reduced total leakage current. With its ultra-miniaturized (5.75 cm³) metal case, the APD HV DC/DC converter series features low radiation noise. The devices are also lightweight (13 g) and allow for flat mounting on printed circuit boards with a height of only 11 mm. 64 models provide voltages from 200 VDC to 500 VDC at a power level of 0.1 W.Tight line and load regulation of <±0.01%, a low temperature coefficient of 50 ppm/°C and a low ripple of 7mVp-p all contribute to the APD series’ very high output stability.
