Product Overview


The DDS986 single phase two wire din rail analog electric energy meter is a high-performance metering device engineered with advanced SMT technology and strict international standard compliance, tailored for ToB clients seeking reliable AC active energy measurement for low-to-medium power consumption scenarios. As a professional Class 1.0 accuracy analog kWh meter, it supports 50Hz/60Hz frequency dual adaptation and features a transparent protective cover for easy visual inspection, making it a staple for power management in residential communities, commercial buildings and small-scale shopping malls. This 220V analog din rail meter boasts a robust structural design, flexible installation options and ultra-low starting current (0.04%Ib), ensuring accurate metering even under light load conditions—an essential feature for property management companies, building contractors and energy service providers. With 39 years of manufacturing expertise behind its production, this meter delivers consistent performance and long-term durability for bulk industrial and commercial deployment.


Key Features & Core Advantages


High Precision Energy Measurement

Equipped with Class 1.0 accuracy certification, the DDS986 meter provides industry-leading active energy metering with a starting current of just 0.04% of the basic current (Ib), eliminating measurement blind spots for low-power electrical equipment. It is compatible with AC220V/230V/240V voltage systems and 50Hz/60Hz global frequency standards, making it a versatile single phase analog energy meter for international ToB projects.


Durable & Fire-Resistant Structural Design

The meter integrates fire-resistant materials with dual sealing technology—ultrasonic seals and screw seals—effectively preventing tampering and ensuring safe operation in high-temperature environments (-25℃~70℃). It offers optional long/short terminal covers, adapting to different distribution box space requirements and enhancing wiring safety for large-scale installation projects.


Flexible Din Rail Installation

Designed for bottom-connected standard din rail mounting, this meter features a compact size (101mm×55mm×165mm) and light weight (0.36kg), enabling quick batch installation in distribution cabinets. Its universal design fits 35mm standard din rails, reducing on-site construction time and labor costs for engineering and property clients.
