Proportional Products


Isolated, Proportional DC to HV DC Converters
100V to 6kV at 1W and 1.5W
Now UL Recognized

The A Series is a new line of ultra-miniature, DC to HV DC converters that sets an industry standard in high voltage miniaturization. This unique package occupies less than one tenth of a cubic inch of volume and features an extremely low profile of only 0.250 inch (6.35mm).

Controllable output voltages range from 100V to 6kV. These component-sized converters are ideal for applications requiring minimal size and weight. Please refer to our AG Series data sheet for surface-mount options.
