LO18-26C0513-03 Datasheet, PDF (1/5 Pages) MORNSUN Science& Technology Ltd. – AC-DC converter for electric meters

LO18-26C0513-03
Three-phase three wire or four wire open frame
switched-mode power supply
High isolated, ultra wide input voltage range
AC-DC converter for electric meters
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
RoHS
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 any two outputs. The product meets IEC/EN61000 "Burst (4kV)",
"Surge (2kV)" and "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.
