Đồng hồ giám sát năng lượng thông minh - EM133

0₫

Model:             EM133

Nhà sản xuất:  SATEC

Xuất xứ:          Isarel


The EM133 can serve any application from residential energy metering, through industrial energy and harmonic analysis through utility comprehensive substation automation. It provides multifunctional 3‑phase power metering, revenue metering and basic power quality information. The EM133 features an internal real time clock (RTC), battery backup and onboard non-volatile memory for event and data logging. The device includes 16 set points and 4 counters that operate the built in 2 DI/ 1RO or the various analog and digital I/O add-ons.

 

The EM133 offers a wide range of network configurations and versatile voltage and current connections: 57 to 400V AC, up to 100A direct current measurement, connection of standard CTs (1A, 5A) and a wide range of remote HACS - High Accuracy Current Sensors (split or solid cores).
