Product Description

SF-E485-II type Data gatechannel

Introduction:
SF-E485-II data gatechannel is an integral part of the low-voltage centralized meter reading system. It is a new generation of collection equipment, which is designed according to the requirements of the State Grid of China to build a power user information collection system and combined with years of design, development and field operation experience in the power industry. The upstream of the data gatechannel exchanges data and receives instructions with the communication front-end through 4G, GPRS, CDMA, Ethernet, optical fiber, etc., and performs real-time meter reading, frozen meter reading and other operations through RS-485 communication. The data gatechannel uses a large memory, which can easily meet the storage requirements of 128 pieces of energy meter data. Mainly used in power companies at all levels, public utilities, public buildings, residential areas and other places.
