HV Series
HV Series High Voltage Dc Power Module

HV series high-voltage DC module power supply is a miniaturized high-voltage power supply developed by Injet for the semiconductor industry. It can be used in ion implantation, electrostatics, X-ray analysis, electron beam systems, high-voltage insulation testing, laboratories, etc.

01

Key features

  • ● Small size, high reliability, simple and convenient operation
  • ● High stability of power output and low ripple
  • ● Using high-precision analog integrated circuits for PWM closed-loop adjustment, the system is stable and the response speed is fast
  • ● High-precision regulation of voltage and current through digital encoder
  • ● The high-voltage power supply has the functions of constant voltage current limiting and constant current voltage limiting
  • ● Series products optional continuous output and pulse output
  • ● System high voltage overvoltage, load ignition protection function

The main parameters

Input Input voltage: AC220V±10% Input frequency: 50/60Hz

Control interface Analog input: 1-way(DC4~20mA；DC0~5V；DC0~10V) Switch value input: 2-way normally open
Switch value output: 1-way normally open Communication: Standard RS485 communication interface, supporting Modbus communication;

 

Expandable Profibus-DP communication
Performance index Control accuracy: 0.2% Stability: ≤0.05%
Voltage ripple: ＜ 0.5% (P-P under constant voltage mode), ＜ 0.2% (rms under constant voltage mode) Control mode: constant voltage and current limiting / constant current and voltage limiting
Protection function Bus voltage protection: when the bus voltage is not within the set value range, the output is cut off , alarm and stop Output overload protection: when the output current or voltage exceeds the set value of protection, alarm and stop
Output voltage protection: if the output voltage exceeds a certain set value and the number of times is too many within 1min, alarm and stop Load ignition protection: In case of load ignition, stop the output and restart automatically. If the ignition times exceed the set value within 1min, alarm and stop
