DTS three-phase electronic power meter

Automatic inspection for phase voltage, and have the function of indication for phase shortage

                                  DTS three-phase electronic power meter

The DTS type three-phase electronic power meter has been selected with the imported three-phase power metering chips, adopted with the SMT surface mounting and the wave-soldering processes for manufacture: the 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 three-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 three-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. Automatic inspection for phase voltage, and have the function of indication for phase shortage

  5. Automatic inspection for the direction of three-phase current, and have the function for indication of current in reverse direction

  6. It can normally work and measure in reverse phase sequence , broken zero wire, power failure in 1 phase or 2 phases

  7 Optional display means including measurement instrument, LCD screen and LED digital tube, etc.

  8. Optional communication interfaces including RS485 and infrared, etc, to fulfill the meter recording on the field or from the remote location
