Single-phase electronic prepaid energy meter is mainly used to measure single-phase active energy and adopts standard guide rail installation. It can realize payment first and then use electricity, and can realize power interruption control. Cooperating with the prepayment system, it can realize card issuance and electricity sales management.
The following is an example of Ankerui Electric Co., Ltd.:
Two main functions
Measuring two-way active energy (reverse counting into forward)
Prepayment function to realize Pay first and then use electricity
Pre-alarm and load control functions
Use logic encryption cards or embedded chips and cards to ensure safe storage of data such as electricity bills
Active energy pulse output, photoelectric isolation< br/> LCD display
Button programming query
Time-sharing multiple rate metering function (optional)
Multi-electric parameter measurement (optional)
R communication, BR protocol (optional) Select)
Matching the card issuance and electricity sales system to realize prepaid electricity sales management
