Leviton 4DUBM-R 4100 Submeter, Universal Voltage Bi-Directional 3-Phase 3-Wire / 4-Wire BACnet MS/TP, USE Rogowski CTs

Gain precise, real-time control of energy flows with the Leviton 4100 bi-directional submeter — purpose-built for renewable energy and modern facilities. This DIN-rail submeter provides accurate monitoring of power imported from the grid and exported by onsite generation (PV, battery systems), supporting 3-phase 3-wire and 4-wire configurations and using Rogowski coil CTs for safe, flexible current sensing. With BACnet MS/TP communications, the Leviton 4DUBM-R integrates directly into building automation and networked monitoring tools, enabling centralized energy management, security-conscious access control, and improved operational visibility. Built to meet ANSI 12.20 0.2% and IEC 62053-22 Class 0.2S standards and backed by CSI approval, this meter delivers revenue-grade accuracy for billing, submetering, and performance verification. Installer-friendly features include DIN-rail mounting, optional outdoor NEMA 4X enclosure, password protection to prevent tampering, and a bright backlit LCD for easy local readings. Ideal for commercial buildings, data centers, and solar installations, the Leviton 4100 submeter simplifies energy monitoring and integration into surveillance, security, and building management systems. Add it to your next energy or BMS project to start tracking exports and optimizing consumption.
