The GP Series is a line of miniature, DC to HV DC converters providing 0.2kVDC to 6kVDC, positive or negative, in a compact PCB mount package.
This line features low power consumption, making it ideal for portable, battery powered applications.
The isolated output is proportional to the input, and is linear from approximately 0.7V in.
A low noise quasi-sinewave oscillator and shielded transformer provide clean, reliable DC to HV DC conversion with low EMI and RFI. The isolated output allows for user selectable output polarity.
No minimum load is required.

*1 Caution: Models GP40, GP50 & GP60 do not have internal bleeder resistors on the output.
      Provisions must be made externally to discharge the output capacitors if this feature is desired.
*2 At maximum rated output voltage.
*3 Output Voltage is load dependent. Under light or no load conditions, reduce input
      voltage so maximum rated output voltage is not exceeded.
*4 Specifications after 30 minutes warm-up, full load, at 25°C unless otherwise noted.
*5 The rated output current is available at full output voltage and derates
      proportionally as the input voltage decreases.
