Baomain DDS238-4 DIN Rail Single Phase Energy Meter – 220V 50Hz 20(100)A – Class 1.0 Accuracy kWh Meter with LCD Display & Pulse Output
The DDS238-4 is a precise single-phase energy meter engineered for accurate power consumption measurement in 220V split-phase electrical systems. Designed to meet Class 1.0 accuracy standards, this DIN rail-mounted meter is an ideal choice for residential and light commercial settings that require reliable energy monitoring.
This single-phase electronic meter features a step-type impulse register and incorporates the latest micro-electronic technology LCD Display. Advanced digital sampling and surface mount technology (SMT) are employed, ensuring accurate recording of total power energy consumption. It has a power indicator that shows when the meter is connected and operational. The impulse indicator, a red LED, clearly displays the impulse rate, providing an easy way to monitor energy usage trends. Compatible with 110/220V AC at 60 Hz, this meter offers a practical solution for a wide range of applications.

Installation Notes:
- Only used under L-N 220 VAC Wire Connection
- CT (Current Transformer) models may be available for higher current ranges.
- Standard Connection (Without CT): Recommended continuous load ≤20A, with short-term peaks ≤100A.
- High-Current Applications (Maximum Current 100A): External current transformers (CTs) must be used. The electrical meter measures high current indirectly via CTs.
Typical Applications:
- Residential energy monitoring
- Small business power tracking
- Electrical sub-metering
- Load management systems
Compliance Information:
- This DIN-rail Kilowatt Hour kwh Meter is designed for AC circuits only.
- It is recommended that the kilowatt meter be installed in the electric meter box.
- For optimal performance and safety, we recommend installation by a qualified electrician professional installation.
