ADL300-EY Din-rail 3-Phase Prepaid Energy Meter
Overview
ADL300 three-phase prepaid energy meter are used to measure single- and three-phase AC active energy with a rated frequency of 50Hz respectively. They have functions such as prepayment control, load control, time control and RS485 communication. The performance indicators comply with GB/T 17215.321-2008 and GB/T 17215.321-2021 standards. It is an ideal meter to reform the traditional electricity consumption system and improve the level of electricity consumption management. The product complies with the requirements of the enterprise standard Q31/0114000129C035-2017 "Enterprise Standard for Rail-Mounted Electric Energy Meters".
