Application

ZMM750SD single-phase electronic energy meter (rail) is our new generation of rail-mounted miniature single-phase electronic energy meter with years of experience in energy metering design.
The electric energy meter adopts LCD liquid crystal display, which can display current active power (including total, sharp, peak, flat, and valley power (optional), current reactive power (optional), current apparent power (optional), Voltage, current, active power, reactive power, apparent power, power factor, grid frequency and other electrical parameters (optional). Prepaid function (optional), built-in magnetic holding relay, cut off during arrears or overcurrent Line power supply. It can be recharged by means of remote communication, automatic trip of arrears, power supply after recharge, low battery reminder. Overcurrent protection function, overcurrent protection threshold can be set, overcurrent trip, communication setting restore power supply It has running status indicator to indicate the current running status of the energy meter. It adopts RS485 communication interface, supports Modbus-RTU protocol, DL/T645-1997, 2007 communication protocol, is to build energy management system, energy saving monitoring system, solar photovoltaic power generation measurement, AC charging piles are ideal for electricity metering and metering for apartments (apartments).
The electric energy meter is mounted on a 35mm standard DIN rail. It has the advantages of compact size, intuitive display and convenient installation. It has the advantages of high precision, good anti-electromagnetic interference, low power consumption, good stability and long service life. GB/T17215.321-2008 "Special requirements for AC measuring equipment - Part 21: Static active energy meter (Class 1 and 2)". Technical requirements for single-phase electronic energy meters.
