Three-phase electric energy meter UEM2L-A R, UEM4L-A R MID

DIN raildigitalmulti-circuit

Description
The UEM2L-A R and UEM4L-A R are three-phase, multi-circuit energy meters with 4 DIN modules, designed for monitoring multiple loads in both industrial and commercial environments.
- They offer simultaneous measurement of two or four independent three-phase loads.
- The meter operates in conjunction with the EMCT series three-phase CT blocks, enabling accurate measurements across four current ranges (160 A, 250 A, 630 A, 1000 A).
- They provide bidirectional measurements across all four quadrants for all energy and power values.
- They comply with Class B according to EN 50470-3 (MID-certified), making them suitable for billing and certified energy accounting.
- The integrated COM port allows for remote management and monitoring of the meter via an RS485 line.
- A dedicated application for remote management is available: Modbus Master software for configuration and monitoring via a PC on an RS485 network.
- A large backlit LCD display, metrological LED, and sealable terminals ensure clear readings and safe installation.
