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.
