- 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.
- This meter series can measure voltage, current, power and active energy in DC system. Not only can it be used as local display, but it can also be used in measuring system by connecting with industrial control equipment and computers. It is a high-performance automation meter that can work with modern DC power distribution system in industrial and mining industry, civil building and building automation.
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).
