Product Detail

SIWOEZ series Three-phase Intelligent Power Meters

Product General

With the rapid industrialization of China, the operating condition and management level of power transformation and distribution system directly affect the user's practical benefits. In order to meet the demand of the customers, Shenyang SIWO Electrical Equipment Co., Ltd. independently designed and developed SIWOE intelligent power meters. Adopting MCU (microcontroller) +high-speed DSP (digital signal processor) architecture, it can measure dozens of power parameters , and has the functions of demand measurement, maximum/minimum value statistics, off-limit alarm, time-sharing energy accumulation , load records , etc. Multiple isolation and anti-interference measures are taken to enable the power meter to adapt to high interference power system. The programmable function makes it have the ability to deal with more and even more complicated logic problems. It not only can meet the requirements for monitoring power transformation and distribution system, but also can realize remote control of power transformation and distribution system and even lay a solid basic for realizing an intelligent power transformation and distribution system.
