EM600C72 series power intelligent monitoring instrument is an intelligent power monitoring device applied to medium and low voltage systems. It has powerful data acquisition, processing, statistics and control functions. It can realize the measurement and calculation of basic single-loop AC power parameters, and the accumulation of electrical measurement, 2～31 Multiple functions such as sub-harmonic analysis, switch monitoring, SOE recording, relay output control, over-limit alarm, and payment rate electricity measurement statistics. Its measurement accuracy reaches 0.2 level. EM600C72 has a segmented 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.
