Voltage&Frequency Stabilizer/AC Power Supply
ER-50W 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.
ER-50W 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.
