Class1.0 220V 10 (40) A 50Hz Voltage loop below 1W 5VA Current loop below 1VA Measurement instrument ( LED OR LCD)
DDS single-phase electronic power meter
The DDS single-phase electronic power meter has been selected with the imported single-phase power metering chips, and adopted with the SMT surface mounting and the wave-soldering processes for manufacture: this product has the features of electric-larceny proof, high precision, high reliability, high overload, low power consumption, small volume, low weight, etc.; it can be widely used in the metering for the single-phase AC active power of urban and rural residents, plant enterprises, business, etc.
Functions and characteristics:
1. Accurately measure the electricity energy with power in the single-phase AC
2. Automatically prevent electricity theft, and the electricity with power in the reverse direction will be calculated into that in the positive direction
3. Broad range, high precision, long life cycle, calibration and maintenance free
4. Optional display means including measurement instrument, LCD screen and LED digital tube, etc.
5. Optional communication interfaces including RS485 and infrared, etc. to fulfill the meter recording on the field or from the remote location or carrier wave
6. Built-in magnet-maintained relay can be configured to fulfill the functions of load control or prepayment.
