Single-Phase Electronic Prepaid kwh Meter
Detailed Product Description
The prepaid electricity meter's specifications
DDSY256 Single-Phase Electronic Prepaid KWH Meter
Introduction
DDSY256 single-phase electronic prepaid energy meter is a full electronic energy meter to measure the active power of single-phase AC electric power grids at 50Hz or 60Hz.
The single-phase active energy meter of this series is in line with GB/T 17215.321-2008 standard and GB/T 18460.3-2001.
Functions and features
(1) This series meter is developed and designed by the company itself with many years in production and marketing, developed technology and reliable performances;
(2) Using imported measurement chip which can accuratly measure two-way electric quantity of the power grid (the reverse is measured positively)
(3) Realize the function of prepayment first and use the electricity. And also the management of one meter one card ;
(4) Alarm function: when the remaining electrical quantity is below the set quantity, the remaining electric quantity can be displayed and remind the user to purchase the electricity in time;
(5) Power usage control: when the remaining electricity falls to zero, it can automatically terminate and restart power supply as soon as the new purchased power card is inserted;
(6) The power control department should install the card writing equipment and power sale management system to record the coded purchased power on the power card, and when the user again inserts the card into the energy meter, the purchased power will be transferred to the energy meter;
(7) Two display configurations: common type (6 digital tube display), counter and digital tube dispaly type
