Multi-Function Power Meter Solution

Release time:2019-08-15 15:54:11

Overview

　　MPM100/MPM110, DEM100/DEM130，are all multi-function power meters, which can be used in the industrial, commercial, utility, transportation, data center, for monitoring electrical power data, such as voltage, current, active power, reactive power, energy, demand, etc. and switch or circuit-breaker ON/OFF status. All data can be display on the screen locally or update to SCADA system.

　　Matched with appropriate PT/VT (potential/voltage transformer) and CT (Current transformer) , Multi-function power meters can be used on the medium-voltage switch-gear, ring-main unit, low-voltage cabinet, switch box or AC junction box. The panel-mounted or DIN rail design make it easy to install on site.
 

Features

• Suit for LV/HV voltage system
• True-RMS measuring
• Cost-effective
• Various DI/DO
• Support RS485 and MODBUS-RTU

Typical application

　　Most of the multi-function power meters are install on the primary equipment, which are sometimes locate in the distribution room, factory workshop, and building strong electrical wells. Meters work as secondary devices, acquisit the data by wire connecting to PTs and CTs which directly detect the voltage and current. Power, energy, frequency and other values can be calculated by meters.

　　Meters send data to gateways via RS485 and MODBUS-RTU, and then gateways send data to SCADA via 2G/3G/4G or ethernet, the protocols are IEC104, MODBUS-TCP, etc.

Application Scenarios/Equipment

　　1) High/medium-voltage switch-gear, Low-voltage cabinet: MPM110/MPM100

　　These kinds of switch-gears and cabinets are always located in the distribution room.
 

　　For the incoming cabinet: always use MPM110. Measuring current, voltage, power, energy, detect switch ON/OFF status, some scenarios also need harmonic and demand.
 

　　For the outcoming cabinet (branch): both MPM110 and MPM100 are ok. Measuring current, voltage, power, energy, detect switch ON/OFF status.
 

　　Both MPM110 and MPM100 has relay outputs, support remote control.

　　2) Power supply cabinet, switch box, AC junction box: DEM100/130, MPM100/110
 

　　These kinds of cabinets or boxes are always located in the factory workshop or building strong electrical wells.
 

　　For electrical monitoring system, always need measuring voltage, current, power, energy, and need to detect the switch ON/OFF status.
 

　　For energy effective management system, always need measuring energy, to statistical energy consumption in each department.
