Product Overview:
UEMCT is a three-phase energy meter for CTs, certified for operation up to 70°C. It supports indirect measurement via standard 1 or 5 A CTs and connection to PTs. The meter features RS485 Modbus RTU or M-Bus communication. It provides bidirectional measurement on 4 quadrants for all energies and powers. Compliance with Class C according to EN 50470-3 (MID) makes it suitable for certified energy accounting with high accuracy. Compatible with 2-, 3-, or 4-wire networks, it ensures reliable measurements even under unbalanced loads. Key electrical parameters can be viewed on the display and accessed via the COM port for remote management, with optional software included. The device features two S0 outputs—one programmable and one fixed—supports up to four tariff management settings, and includes a metrological LED and sealable terminals for immediate reading and protection. Optional software is available for device management.
