DU2 Series High Voltage Supply Module

Description

TestUni’s DU2 series is a high-precision, compact DC/DC high voltage power supply module. The rated output voltage ranges from 0V to -20kV and the maximum output power is 20W. The power supply is characterized by low output ripple, high linearity, high stability and small temperature drift coefficient. The user can linearly adjust the output voltage by external control voltage or multi-circle potentiometer. The shell is made of metal material with low resistance and high permeability, which results in a good electromagnetic shielding function.

Product Characteristics

  • Low noise, small output ripple
  • Low time drift and temperature drift
  • The output voltage is continuously and linearly adjustable
  • Good output overload and short circuit protection function
  • Small size, low power consumption, high stability
  • Quick rise-time

Wiring diagram

Notes:
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.
