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 RoHS 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. FEATURES 1.
