Product Introduction

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.
