summary:
Multi functional power meters are the new generation of miniature rail type energy meters developed by our company based on years of experience in meter design. This instrument adopts LCD display, which can set parameters such as clock, rate period, etc., and has the function of outputting electric energy pulses; RS485 communication interface can be used to exchange data with the upper computer, greatly facilitating the automation management of electricity consumption. This instrument has the advantages of small size, high accuracy, good reliability, and easy installation. Its performance indicators meet the technical requirements of international GB/T17215, GB/T17883, and DL/T614 for instruments in the power industry.
