TOU Energy Meter & Multi-Functional Smart Power Meter
EM133
SATEC EM133 is a Smart DIN Rail TOU Energy Meter, featuring 16×2-character LCD display, 2 Digital Inputs, 1 Digital Output, IR (Infra-Red), battery backed up real time clock (RTC) and up to 8MB memory for data logging.
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).
