Ultra wide input voltage range open frame switched-mode power supply for electric-meter application
This AC-DC converter is designed for electric-meter application and operates over a very wide input voltage range: 65-460VAC
or 90-650VDC. It means that this converter can operate with any two wires connection from the three-phase three wire or
four-wire system. When failures happen in the lines system resulting in input over-voltage, the converter will shut down to protect
itself and the terminal devices from damage, improving the reliability of the system. The product has two output voltages: 5.3V
and 12.6V. The isolation voltage is 4000VAC between input and output. The product meets IEC/EN61000 "Burst ", "Surge " and
" CISPR22/EN55022 Class B Conduction/ Radiation".So it is a design solution for electric-meter application sourced from a
three-phase AC supply with the requirement of high isolation voltage and rigorous EMC.
