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 MORNSUN® FEATURES • Ultra wide input voltage range: 57 - 528VAC/80 -745VDC • Working well with any two phases • CE/RE: CISPR22/EN55022 CLASS B • EFT /Surge: ±4KV Perf. Criteria B • Output short circuit, over-current, over-voltage protection • High efficiency, High reliability • Low ripple & noise, Low standby power consumption • Long-life, low ESR electrolytic capacitor LO10-26D0512-04L—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: 57-528VAC or 80-745VDC. it means that this converter can operate with any two wires connection from the three-phase three wire or four-wire 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 Conducton/ Radiat'on' So it is a design soiuton for electric-meter appiiccriion sourced from a three-phase A C supply with the requirement of high iso/at'on voltage and rigorous EMC.

MORNSUN® Over-voltage Protection Note: * Ripple and noise are measured by “parallel cable” method, please see AC-DC Converter Application Notes for specific operation. Note: ©Input voltage should be derated based on temperature derating when it is 57 - 100VAC/80- 120VDC; ©This product is suitable for use in natural air cooling environments, if in a closed environment, please contact our company's FAE.

Efficiency Vs Input Voltage (Full Load) Output Current Percentage(%) Input Voltage(VAC) Design Reference 1. Typical application circuit A C (L) Fig. 1 Note: Output filtering capacitor C2/C4 is electrolytic capacitor, it is recommended to use high frequency and low impedance electrolytic capacitor (recommended value, C2: 220μF/10V; C4:100μF/25V). Capacitor withstand voltage derating should be 80% or above. C1/C3 is ceramic capacitor, which is used to filter high-frequency noise, recommended to use 0.1μF/50V. It is recommended that the 5.1V main output circuit add TVS1 (P6KE6.8A) and the 12V auxiliary...
