TOU Energy Meter & Multi-Functional Smart Power Meter

SATEC EM133 is a Smart DIN Rail TOU Energy Meter. It is based on SATEC’s best seller PM130 PLUS with an off‑the-shelf LCD display (similar to the BFM136 display). The EM133 provides the full functionality of the PM130EH PLUS combined with 2 Digital Inputs, 1 Digital Output, IR (Infra Red) communication and battery backup for the real time clock. It is fully compatible with all PM130 PLUS modules.

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 Quality Current Sensors (split or solid cores).

The EM133 - comprehensive multi-functional energy meter, which provides a complete range of energy measurement and management. It measures the electrical energy and connects via digital inputs to water, gas or air condition meters. A built in relay output can be freely programmed to remotely disconnect the supply (using external contactors) or raising alarms. The information is displayed locally and is available via communication.
