15W AC DC open frame switching power supply with three outputs
15W AC DC open frame switching power supply three output
Descriptions
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 widei nput voltage range:65-460VACor90-650VDC.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 strict electromagnetic compatibility.For extremely harsh EMC environment,we recommend using the application circuit show in Design Reference of this datasheet.
