ER-50W Series Features: 1. High reliability and availability; 2. Galvanically isolated,low harmonic distortion; 3. Isolated output transformer,suit for any unbalance loads; 4. Every single phase can be used independently; 5. Thoroughly proven advanced SPWM and IGBT technology; 6. Pure sine wave,sinusoidal output; 7. Better overload capacity.
Voltage&Frequency Stabilizer/AC Power Supply
ER50W series voltage&frequency stabilizer/AC power supply is utilizing the rectifying and inverting technology to convert the unsteady electricity from +/-30% variable into steady status with galvanically isolated, single phase or three phase power source.
ER50W Series are designed to prevent the sensitive electronics/heavy duty electric equipment from damage when they are supplied under unstable state electric grid/generator, such as flicker, power drops etc. It integrates IGBT made by Mitsubishi, Siemens, and combines analogsignal controldesign together for compact sizeand higher reliability. It’s widely application in factory manufacturing, technology researching as well as home appliances.
