prepaid meter and prepayment meter and single phase meter and electric meter with IC card
Service DDSY256, watt-hour meters are the stationary watt-hour meters made by the special LSI circuit and the SMT manufacturing technology. Servicing the stepper to record the electric energy. Or the character to do so ,these meters are capable of preserving date at power down. And recording at both directions, also with the stable measuring accuracy. 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 meters are in conformity of the standard IEC 1036-1996.
|Main functional 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. hit precision, low power consumption, large load range and easy installation.
