Gernaalong DDS-1Y Single-Phase Digital kWh Energy Meter

The Gernaalong DDS-1Y is a compact, modular single-phase digital electronic $kWh$ meter designed for precise real-time active power tracking in standard low-voltage electrical circuits. Engineered in compliance with global IEC62053-21 metrology standards, this sub-meter delivers Class 1 measurement accuracy. Its narrow, space-saving footprint is optimized for direct standard DIN-rail mounting, providing an efficient energy telemetry solution next to localized branch circuit breakers.

Key Features

High-Accuracy Active Energy Tracking: Built to calculate active power variables over single-phase alternate networks with a stable Class 1.0 accuracy rating.
Clear Digital LCD Window: Features a built-in, low-consumption digital LCD screen that provides highly visible field diagnostics and accumulated consumption statistics.
Integrated Consumption Pulse LED: Features a front-panel red ‘Pulse’ LED calibrated at 1000 imp/kWh, blinking proportionally to consumption speeds for easy manual checking.
Straightforward Line/Load Layout: Designed with clear top ‘Source’ (Line/Neutral) and bottom ‘Load’ (Line/Neutral) terminal paths to prevent configuration errors.
Ultra-Compact DIN-Rail Design: Its narrow profile maximizes available layout space inside crowded multi-tier sub-distribution board assemblies.
