DC Energy Meter

Product catalog summary

Introduction
The DCEM series DC energy meters are designed to monitor DC circuits, measuring basic power, demand, extreme values, and combined electric energy. They also measure DC current and electrical parameters, featuring an RS485 communication interface with an accuracy class of 0.5.

Applications
These meters are used in communication base stations, solar panels, car charging stations, and DC panels. They are compatible with DC shunts or transformers.

Catalog excerpts

i Introduction DCEM series DC energy meter is mainly used to monitor the DC circuit, which can measure the basic power, demand, extreme value of the DC circuit, and measure the combined electric energy. Moreover , it can measure DC current and DC system electrical parameters. All DC metering device is with RS485 communication interface and the accuracy class is 0.5. DC metering offered by Blue Jay includes DCEM-7MS, DCEM-5MC, DCEM-96S and DCEM-3MS. It can track the performance of DC systems on multiple parameters. They are used in conjunction with DC shunts or DC transformers, widely used in communication base stations, solar panels, car charging piles, and DC panel. • Small and portable, easy to install. • Powerful data acquisition and processing functions. • Ultra-clear screen display, clearly view the measurement results. • Fast response,rapid measurement of current or voltage changes. • High precision for accurate current, voltage and resistance measurements. • High voltage shock resistance reaches level 4; surge antiinterference to level 3. • Electrostatic discharge immunity reaches level 3; electrical fast transient burst immunity reaches level 4.
