 Introduction

  Intelligent DC Regulated Power Supply is a kind of continuously adjustable Iinear DC voltage stabilizing power-supply for zero voltage to rated voltage value. It is mainly composed of by disconnection transformer, controlled rectifier pre-stabilizing voltage circuit, linear voltage stabilizing circuit and filteringcircuit. The power-supply can be working under constant voltage output way or constant current output way. When it adopted the constant current output way, the output current can be adjusted from zero to rated value. This series power supply has two routes of complete protection circuits, so it has good reliability and is ideal DC voltage stabilizing power-supply for colleges, factories and science offices.

Application

  1 Accumulator charging, PCB exposure light power supply
  2 Aging test for resistor, relay, engine etc.
  3 Experiment, electronical equipments, auto-test equipments
  4 Electronical test equipments, product line equipments, communication equipments
  5 Other situations need DC power supply

Notes

  1) Input voltage: power source voltage can be changed on requests
  2) Custom-made specifications are available
  3) The website specifications are only for your reference, the actual specificities depends on attached specifications.
