Product Description:

ERD/S50 series of constant voltage constant frequency power supply adopt ARM, MCU, DSP, FPGA as core processor. single polarity double frequency technology. the frequency synthesis adopts DDS digital frequency synthesis technology. DC section is equipped with large DC capacitor (DC link). This series are specially designed to solve power grid’s problem. such as voltage instability, frequency instability, large harmonic content, voltage drop and flicker. Suitable for various loading equipment that require better power grid quality.

Features:

●Wide input voltage: (90V ~ 290V), wide input frequency: (25Hz ~ 75Hz).

●Key components are originally imported. design of enough redundancy. powerful loading capability.

●Equipped with special isolation transformer and filter. output is pure sine wave. less harmonic. the whole machine is safe and reliable.

●Display parameters of voltage, current, power, etc. protect functions of over current, over voltage, over temperature, IGBT fault, etc. meanwhile, protection value could be set via touching screen and protection functions could be switched freely.

●Efficiency reaches to 90%. adapts to various capacitive load, inductive load, rectifier load. fast dynamic response speed. 

●Adopt full digital control and feedback technology. dual closed-loop control algorithm for output voltage and load current. fast control speed. high precision.
