Application

        The DDS686, watt-hour meters are the stationary watt-hour meters made by the special LSI circuit and the SMT manufacturing technology. This meter is capable of preserving date at power down. The three-watt-hour meter is supplied by the three-phase power so when the single-phase or the two-phase power is interrupted there is no effect the measuring accuracy.

        The DDS686 single-phase electronic power meter adopts specialized LSI, the device typifying new periphery component, simple structure, high reliability, low power consumption, long life etc. It is suitable for the single-phase AC active electric energy with rated frequency of 50Hz.

        The product conforms to GB/T17215.321-2008 standard in performance.

Functions and features

1. The product has the function of two-way counting, which can accurately measure the power of positive and reversal direction, with one direction accumulating the quantity of electricity, so as to prevent, the electricity-theft.

2. The product adopts the photoelectric isolated technique to produce the electric energy pulsed signal, and the light emitting diode (LED) to indicate the electricity consumption.

3. The product has the function of augment ability, for example, it can be provided with a carrier, so that the concentrated recording will be carried out.

4. The product is provided with the small size, lightweight, low power consumption, large load range and easy installation.
