Key features, benefits and applications of the CHVM high voltage DC-DC converter modules
The 12V input CHVM series of non-isolated, point-of-load (POL) DC-DC converters offer output voltages of up to 2kV in compact PCB-mount formats. Three package sizes cover power levels from 1.4W to 3W. Remote on/off is standard across the range, and the output is adjustable from 0.5% to 100% of the rated voltage using either an external variable resistor or applied voltage.
Five-sided shielding reduces radiated emissions and contributes to a very low output ripple and noise, reducing external filtering requirements. Therefore, the CHVM is ideal for precision, noise-sensitive applications such as photomultiplier tubes, photodiodes, scanning electron microscopes (SEM), ultrasound imaging, bio-diagnostics, X-ray fluorescence spectrometers, mass spectrometers, and ultrasonic probes.
The CHVM series comes with outputs ranging from 180V up to 2,000V in either a positive or negative polarity. All models within the series are protected against an over-current condition. The CHVM will start up at -20°C. The operating temperature range is -10°C to +50°C for the 1.4W and 1.5W models, and -10°C to +60°C, derating linearly to 60% load above +50°C, for the higher power models. Safety certification includes IEC/UL/CSA/EN 62368-1, which simplifies system compliance.
