single phase din rail power meter

DDSD318 single-phase DIN-rail energy meter addresses critical energy monitoring needs across diverse sectors, serving as an essential tool for optimizing power consumption and cost management. Designed primarily for integration into photovoltaic power generation systems, commercial buildings, industrial plants, and government facilities, this device provides comprehensive real-time measurement of key electrical parameters including voltage, current, active power, frequency, power factor, and bidirectional active energy (forward/reverse).

Its core functionality centers on enabling precise energy accountability through RS485/MODBUS communication, allowing seamless integration with centralized energy management systems for remote data collection, automated billing, and load analysis. The meter supports advanced applications like tenant submetering in multi-unit buildings, solar performance tracking in PV installations, and peak-demand cost allocation in manufacturing environments. The optional relay function extends its utility to prepaid electricity systems and remote load control scenarios.

Installation flexibility is ensured through standardized DIN-rail mounting (35mm), making it suitable for retrofit projects and space-constrained electrical cabinets. Operational features include anti-tamper protection, automatic display cycling of critical parameters, and pulse output for calibration verification. Designed for reliability in demanding conditions, it maintains accuracy across industrial temperature ranges (-25°C to +60°C) while complying with international metering standards.

By delivering granular energy visibility without complex infrastructure changes, the DDSD318 empowers facility managers to identify waste, implement tiered pricing strategies through configurable tariffs, verify renewable energy contributions, and ultimately drive more sustainable operations. Installation and maintenance require qualified personnel to ensure safety and compliance.
