WHFW-GJD-Series High-precision Enabling Power Supply
Product Detailed
1:Programming 2:SCR firing control&output regulation 3:Parameter&Alarm Indication 4:Interfacing with external PC or PLC

Summary

The product adopts IGBT inverter soft switch linear rectifier, DSP computer digital control and instantaneous value of double closed loop phase-locked loop control system, quick output response speed, ripple coefficient is extraordinary small and high stable precision. Output current and voltage is continuous and adjustable. It is mainly applied in factory aging enabling test power supply of military service gall capacitor. It can also be used in DC power supply applications of high precision, high stability, high reliability and low ripple like aviation, aerospace, ship and national key lab etc
