The EM600C96 power monitoring instrument is an intelligent power monitoring device used in medium and low voltage systems. It has powerful collection, processing, statistics and control functions. It has the measurement and calculation of three-phase AC power parameters, electrical measurement accumulation, 2 to 63 harmonic analysis, Power pulse counting, switching value monitoring, fault recording, relay output control, DC transmission output, power pulse output, over-limit alarm, temperature measurement, multi-rate electricity measurement statistics and other functions. Its measurement accuracy reaches 0.2 level. EM600C96 has a segment LCD display, which can display all electrical parameters in real time. At the same time, it can be connected to the EasyECM integrated monitoring system (or third-party system) of ESDTEK through the RS485 communication interface to form a complete automated monitoring system. EM600C96 adopts a variety of anti-interference measures and can operate stably in the harsh power system environment. The external dimension conforms to DIN96×96 standard, and adopts self-locking installation mechanism, which can be installed without screw fixing. It can be widely used in electric power, construction, industry, transportation, data center and other industries.
