DTS237-1 type three-phase electronic energy meterDetailed product description：

The DTS237-1 three-phase electronic energy meter is used to measure three-phase AC active energy with a rated frequency of 50Hz. It has the characteristics of high accuracy, long working life, strong anti-interference ability, wide load range, low self power, small size, and light weight. The measurement accuracy is not affected by frequency, voltage, temperature, and high-order harmonics.
There are two display modes: metering mode and LED mode. The measuring device adopts a reverse measuring device, which is resistant to strong magnetic interference and has a high cost-effectiveness; High brightness large digital tubes are selected for display in LED mode, especially for outdoor and nighttime meter reading.
