G Series DC-HVDC CONVERTER CONVECTION 1.5W COOLED The G Series is a line of miniature high voltage converters that provide up to 6kV output, positive or negative, in a compact PCB mount package. The isolated output is directly proportional to the input, and is linear from approximately 0.7 volts in. Excellent filtering techniques and a low noise quasi-sinewave oscillator provide clean, reliable DC to HV DC conversion with low ripple and low EMI/RFI. The isolated output allows for user selectable output polarity. When the optional center-tap pin is grounded, the unit provides both positive and negative outputs from one compact, low cost module. The pin paern used on this model has bectt ome an industry standard for high voltage modules. The G Series units are component level converters that are easy to integrate, low cost, and come with decades of field proven reliability.
