LO18-26C0513-03----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 isolation voltage is 4000VAC between input and output, and two outputs. The product meets
IEC/EN61000. 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.

Note: Output filtering capacitor C2/C4/C6 is electrolytic capacitor, it is recommended to use high frequency and low impedance electrolytic capacitor.
Capacitor withstand voltage derating should be 80% or above. C1/C3/C5 is ceramic capacitor, which is used to filter high-frequency noise. TVS is a
recommended component to protect post-circuits if converter fails.
