Voltage & Frequency Stabilizer/AC Power Supply
Introduction
ER-PS-50W series stabilized frequency stabilizer/AC Power Supply adopts rectification and inverter technology, which can convert unstable power from +/-30% variable voltage to a stable state of galvanically isolated single-phase or three-phase power supply.
The ER-PS-50W series is to prevent sensitive electronic/heavy-load electrical equipment from being damaged during unstable grid/generator power supply, such as flickering, power failure, etc. It integrates Mitsubishi and Siemens IGBTs, and combines analog signals to control the design to achieve compact size and higher reliability. It is widely used in factory manufacturing, technical research and household appliances.
