A series of high-voltage power supplies has been unveiled by Emco High Voltage Corp. The CA line features ripple at 2 ppm peak to peak, stability of 0.001%/h and a temperature coefficient of less than 25 ppm/°C. These miniature modules occupy 1 in.3, weigh less than 1.5 oz and include an onboard precision reference and output voltage monitor. They have low electromagnetic and radio-frequency interference emissions and accept 11.5 to 15.5 VDC. Ten models provide 0 to 250 V through 0 to 2000 VDC, available in either positive or negative output voltage polarities.
