Product Introduction

The DDZY188-Z adopts the most advanced dedicated integrated circuits for energy meters, microprocessors, non-volatile memory for permanent data storage, wide-temperature LCD display technology, and SMT manufacturing processes. It is a high-precision, wide-load-range, high-sensitivity, low-power-consumption AC energy meter. This smart meter accurately measures active energy in both forward and reverse directions, as well as energy consumption under different tariffs. It features forward and reverse active power measurement capabilities and performs real-time measurement and processing of electrical parameters including active power, voltage, current, power factor, and frequency. The meter supports time-of-use (TOU) metering, automatic meter reading, data storage for energy consumption, load profile recording, event logging, and other advanced functions.
