Product Introduction

SPM91 offers a cost-attractive, competitive range of single-phase DIN rail-mounted energy meters ideal for business, industrial and residential applications. Combined with RS485port, Modbus-RTU or DL/T 645 communication protocol, it makes easy to integrate electrical distribution measurements into Smart PiEMS energy management system.

SPM91 DIN rail energy meter is a kind of new style single phase whole electronic type meter. The meter is completely conformed to the relative requirements of the International Standard IDT IEC 62053-21:2003 (Class 1). 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.

SPM91 is used for measuring active energy, voltage, current, active power, reactive power, apparent power, power factor, input active energy, output active energy, input reactive energy, output reactive energy, total active energy, total reactive energy in a rated frequency of 50Hz or 60Hz single phase alternating current circuit. It displays total active energy, voltage, current, active power via LCD and is characterized with good reliability, compact size, light weight, specious nice appearance and easy installation.
