Single Phase Prepaid Static Energy Meter (DDSF876-C1)

Product Description

Single Phase Prepaid Energy Meter with IC Card is used for measuring the single phase a. c. active energy, and also can realize the function of prepayment of quantities of electricity. It adopts the high quality long lifetime components and SMT manufacturing craft, the micro-processing and electromagnetic compatibility(EMC) technology, and is reliable in performance.

It conforms to IEC 62053-21 standard: Static meters for active energy (Class 1 and 2), and the standard of GB/T 18460. 3-2001 or any other standard appointed by the buyer. Prepaid Energy Meter. Techrise also can design and produce the meter as per the standards offered by the buyers.

Main Technical Features:

High accuracy: Adopting the high quality special
metering chip; Stable errors; Good linear; No
need for calibration for a long term service.

Stability and reliability: Strong ability to withstand the interference and overloading. Adopting the magnet-keeping relay; Valid control of power on or off.
long lifetime: Using the advanced SMT manufacturing craft; Long lifetime of main components.

Data feedback: IC card will feedback the total consumed(prepaid) energy and the others information to the vending machine in order to duly know the conditions of energy consumption.

Alarm function: When the residual energy is not enough, the alarm lamp will flash firstly and then power off will happen in order to remind the users to prepay.

Automatic trip: Trip when the residual energy is zero, and the power on will not be restored by inserting the card until the new prepayment.

Energy inquiry: Circle display of the accumulative energy, total prepaid energy and residual energy after inserting the card.

Strong ability to withstand destruction: The inside metering and control won't be affected when the card holder is destroyed by the external attack

Tamper and fraud protection: With the protection function of the shorted circuit, the reversal connection of phase wire and neutral wire, and the neutral wire connecting to the earth.

One meter with one card: Each electric card is only used for one meter after the special encryption in order to prevent the technical tamper.
