Smart PiEMS System
- SPM93 is completely conformed to the relative requirements of the International Standard IDT IEC 62053-21:2003 (Class 1 ), IDT IEC 62053-22:2003(Class 0.5S ). It is an integration of up-to-date micro-electronics technique, special large scale integrate circuit, advanced technique of digital sampling technique and SMT techniques etc.. Combined with RS485 port, Modbus-RTU or DL/T 645-2007 communication protocol, it makes easy to integrate electrical distribution measurements into Smart PiEMS energy management system and Smart PiDMS distribution management system.
- SPM93 three phase energy meter is used for measuring active energy power
consumption in a rated frequency of 50Hz or 60Hz three phase alternating current
circuit. LCD display total kWh (Imp. & Exp.), total kWh (Imp. & Exp.), Multi-tariff
energy, voltage, current, power, power factor, frequency. It is characterized with good
reliability, compact size, light weight, specious nice appearance and easy installation.
