DC Multifunction Energy Meter
At Big Belly Sales Corporation, our DC Multifunction Energy Meter is designed to provide highly accurate, real-time measurement and monitoring of direct current (DC) electrical systems. Engineered for a wide range of DC applications — from solar installations to EV charging infrastructure, telecom power systems, battery storage, and industrial DC power networks — this meter ensures precision, robustness, and seamless integration with energy management systems.
Key Features
Our DC meter supports external shunt-based current measurement (1 A up to 9,999 A selectable), with a DC voltage measurement range of –1,500 V to +1,500 V. It can measure instantaneous power (kW), cumulative energy (kWh), import/export energy, and direction of current flow, giving you full visibility into your DC power system. With high accuracy (class 0.5), you can rely on precise data for billing, energy audits, and system optimization. The meter is equipped with two relay outputs for alarms or control, and supports RS-485 Modbus for remote communication. :contentReference[oaicite:0]{index=0}
Construction & Design
Housed in a compact, rugged panel-mount enclosure, the meter is built to industrial standards. It uses advanced microcontroller-based signal processing for reliable measurement. The front-facing LCD provides a clear, user-friendly interface. Two relay outputs enable local control or alarms based on set thresholds. It supports standard DIN rail or panel installation, with terminals designed for secure shunt and power connections. RS-485 communication ensures seamless integration with EMS, SCADA, or mobile monitoring platforms.
