DV1 Series High Voltage Supply Module


TestUni’s DV1 series is a plug-unplug lead type, high precision, small volume DC/DC high voltage module power supply. The rated output voltage is adjustable from 0V to 30KV and the maximum output power is 30W. The power supply is characterized by low output ripple, high linearity, high stability and small temperature drift coefficient. The user can adjust the output voltage continuously through external control voltage or external adjustment of multi-circle potentiometer. The shell of power supply is made of metal material with low resistance and high permeability, which results in a good electromagnetic shielding function.

Product Characteristics

  • The output voltage is continuously and linearly adjustable
  • Low noise, small output ripple
  • When drift, temperature drift small
  • The output voltage is continuously and linearly adjustable
  • With overload and short circuit protection function
  • Small size, low power consumption, high stability
  • Fast transient response



Typical Application

Used in spectrometer, chromatograph, mass spectrometer, ion migration spectrum, night vision instrument and other instruments, for medical chemical industry, security equipment, scientific instruments, communications and transportation, scientific research, national defense and other fields.

Wiring diagram


  1. The potentiometer adjustment mode must use high precision multi circle potentiometer with resistance ≥ 10K Ω
  2. The external control voltage regulation mode must use DC control voltage with high stability and low ripple
  3. GND, SGND and HGND have already been connected internally and connected to the power supply shell
  4. R/S Connects to TTL high and low levels

Control-output Curve Relationship

Main Precautions

  • To ensure the technical indexes of high-voltage power supply and reduce mutual interference, it is recommended to use independent voltage power supply.
  • When connecting with the external circuit, please ensure the accuracy of the connection and ensure there is no loose connection or short circuit, to avoid damaging the power supply and users’ equipment.
  • Keep a certain insulation distance near the power output end to avoid high voltage arcing or ignition with surrounding components.
