1. Product Overview
SPM90 is designed for scenarios such as DC panel, charging pile and
telecom base stations. 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
electrombile) and Class 0.5 of DL/T 1484-2015 (Technical Regulations of DC
energy power).
Main function of this product:
Real-time measurement of electrical parameters: voltage, current
and power
Measurement of bidirectional energy
1CH RS485 communication, 1CH electric pulse output optional.
