1.Application
The DDSY5558 represents a breakthrough in keypad prepayment metering technology. This innovative meter allows customers to conveniently purchase energy through our vending network, receiving a unique 20-digit serial number known as a 'TOKEN'. This TOKEN, which is encrypted for security, is entered via the meter's keypad, seamlessly transferring credit data to the meter upon acceptance. Popularly referred to as the 'Keypad meter', this device adheres to the open standard STS, ensuring reliability and compatibility.
2.Feature
Effortless payment through a secure 20-digit token system.
Advanced alert system for low energy, overload, and fraud detection.
Integrated RS485 and optical communication capabilities for efficient meter reading and parameter configuration.
Innovative open terminal cover detection alarm for enhanced security.

4.Function
4.1 Energy Measure
Accurate bidirectional active energy measurement, converting reverse energy to positive energy. Equipped with pulse LED and pulse terminal output for precise monitoring.
This intelligent meter records both remaining and accumulative energy, allowing operators to effortlessly monitor current energy levels. Automatic relay disconnection occurs when energy dips below zero, with reconnection happening once energy levels are topped up.
4.2 Charge energy
Operators can seamlessly recharge energy using STS encryption, inputting a 20-digit cryptograph to replenish deposit Energy to the remaining energy balance. The meter displays 'ACCEP' to confirm successful transactions.
If the combined recharge and remaining energy exceeds 9,999,999.99 kWh, recharging is temporarily halted, but the token remains valid for future use when total energy falls below the limit. The meter will display 'REJECT' to indicate this condition.
The system carefully verifies token time stamps to prevent duplicate charges, allowing only one charge token per minute. Identical tokens generated within the same minute are declined, and 'REJECT' is displayed.
The meter logs the last 50 token usages, rejecting any token generated earlier than these entries and displaying 'REJECT' for transparency and security.
4.3 Anti-tamper alarm
Anti-tamper:
Our electronic energy meter is equipped with an intelligent alarm system, instantly detecting tampering attempts such as reverse wiring or unauthorized cover opening. The alarm remains active until a specific tampering clearance command is entered, ensuring unauthorized access is swiftly addressed.
In the event of tampering, the 'Token' system requires a reparation token input to clear tampering status. Furthermore, the 'Repair' function automatically deactivates tampering alerts when the issue is resolved.
