DDSY23 Single phase electronic prepaid energy meterDetailed product description：

summary:
The DDSY23 single-phase electronic prepaid energy meter is used to measure single-phase active energy with a rated frequency of 50Hz/60Hz, while also performing prepaid electricity management and load control functions for purchasing electricity before using it. All its performance meets the technical requirements of level 1 and level 2 single-phase electronic prepaid energy meters in GB/T17215-2002 and GB/T18460.3-2001 standards.

Function:
This prepaid energy meter supports one meter multiple cards and one card multiple meters, but only accepts all legal cards within the specified system to ensure that user cards outside the specified system cannot be used. This prepaid energy meter can be widely used in places with high personnel flow, uncertain users, such as hotels, schools, government agencies, commercial markets, or public facilities, as well as for agricultural irrigation. Administrators sell electricity through the electricity sales system, and users insert the purchased and issued user card into the energy meter to achieve pre purchase of electricity. When the pre purchased electricity in the user card is used up, the energy meter will automatically power off, and the user must purchase electricity again before continuing to use it; At the same time, when the user unplugges the user card, the energy meter will immediately cut off the power supply. All user's electricity usage information is stored in the user card, and the administrator can read all user's electricity usage information through the electricity sales system for payment and other operations.
