Descriptions

LO20-26D1212-04-C State Grid TTU dedicated switching power supply.The AC-DC converter is a three-phase four-wire power dedicated Switching power supply designed for intelligent distribution terminal,intelligent power distribution detection terminal,etc.According to the latest national grid company enterprise standard and operates over a very wide input voltage range:165-480VAC or 230-680VDC.It meets the three-phase three wire or four-wire rated voltage.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,for extremely harsh EMC environment,we recommend using the application circuit show in Design Reference of this datasheet.

Features

l Designed for intelligent distribution and transformer terminals, the main technical indicators meet the national network standards
l Ultra wide input voltage range: 165-480VAC/230-680VDC
l High I/O isolation test voltage up to 4000VAC
l EFT, Surge: ±4KV Perf. Criteria B
l Output short circuit, over-current, over-voltage protections
l High efficiency, high reliability
l Low output ripple & noise, low standby power consumption
l Input anti-double rated voltage, normal over-voltage output
