LO10-26D0512-04 Datasheet, PDF (1/4 Pages) MORNSUN Science& Technology Ltd. – AC-DC converter for electric meters

LO10-26D0512-04
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 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 "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.
