DDS Single-Phase DIN Rail Energy Meter DDS662 DDS667 DDS668 Series 110V 230V

The DDS series covers three models of compact single-phase DIN rail energy meters designed for accurate, reliable metering across residential, rental, commercial, and light industrial installations. All models are rated 5(80)A and compatible with both 110V/230V 50/60Hz power systems, making them suitable for domestic and export markets worldwide.

The DDS662 is the foundation model — a straightforward, wide-input energy meter with a clear LCD display showing kWh, voltage, current, and power. It supports both 110V and 230V at 50/60Hz and includes a pulse output at 1600 imp/kWh for external data logging and sub-metering systems. Long service life and high reliability make it a proven choice for residential sub-metering and light commercial energy monitoring.

The DDS667 adds a backlit LCD for clear reading in low-light conditions such as enclosed distribution cabinets and basement meter rooms. An operation button enables manual data switching and reset, giving users direct control over the displayed parameter and consumption records. Available in 110V/60Hz and 230V/50Hz versions to cover North American and international grid standards.

The DDS668 is the most capable model in the series, displaying the full parameter set: kWh, voltage, current, active power, power factor, and frequency. The backlit LCD supports both manual and automatic scrolling display modes, and a reset function allows flexible usage monitoring for rental billing, tenant sub-metering, and energy management applications. Certified for international power distribution systems.
