Overview
Modular Multi-Function Energy Metering System
The 19D-NX is a next-generation modular DIN-rail power meter designed for flexible on-site integrated metering. By utilizing 3M width expansion modules, it can scale to support up to 40x3P4W or 120x1P2W energy metering systems, making it ideal for complex tenant sub-billing and cost allocation. Featuring a 6-inch dot matrix LCD and programmable digital inputs/outputs, it provides high-precision monitoring for energy efficiency and procurement optimization.
