Description

The Eastron SDM54-DM is an industrial-grade three-phase 45 A direct-connected energy meter engineered for high-precision measurement in commercial and industrial environments. This MID B+D certified unit provides Class B accuracy, making it an ideal choice for fiscal sub-metering and cost allocation. Beyond simple energy counting, the SDM54-DM quantifies a vast array of electrical parameters, including voltage, frequency, power factor, and total harmonic distortion (THD). With its compact DIN rail footprint and bi-directional measurement capabilities, it is a practical solution for monitoring modern loads and renewable energy exports.

Industrial Precision & Communication

Bi-Directional Measurement Perfect for solar PV installations, tracking both imported energy from the grid and exported energy for comprehensive site analytics.
Smart System Integration Equipped with a built-in RS485 Modbus RTU port and two configurable pulse outputs, allowing for seamless integration into BMS and SCADA systems.

Professional Usage Scenarios

• Commercial Sub-metering: Accurately bill individual tenants or departments in office complexes and shopping centers.
• EV Charging Stations: Monitor current draw at charging points up to 45 A per phase for accurate user billing.
• Energy Management: Track power quality parameters like THD and Power Factor to improve efficiency and avoid utility penalties.
