Product Introduction

SPM90 single phase dc energy meter parameters

SPM90 offers a cost-attractive, competitive range of single-phase DIN rail-mounted energy meters ideal for DC panel, charging pile and telecom base stations applications. 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.

Product performance fully meets the according technical requirements of GB／T 29318-2012 (Energy measurement of non-vehicle charger of Electromotive) and Class 0.5 of DL/T 1484-2015 (Technical Regulations of DC energy power).
