Dual Source Generator and Grid Single Phase STS prepaid Energy Meter
with Vending Software
The dual source single phase prepaid electricity meter is designed for those area where is no reliable power supply from the Grid in Africa. The meter can switch the measurement between the Grid and Generator automatically and have a separate bill.And the meter can auto decrypt the recharge code from different source and top up into separate balance.
This meter is STS (Standard Transfer Specifications) approved, complete in BS footprint. The meter is also allowing a basic current of 5 Amp while retaining a maximum current of 80 Amp, and extended AMR/AMI system --- reading the meter remotely, shut off the meter remotely, daily/monthly report, data analysis, etc.
.
Main Features
1) Dual source measurement
2) RF-Lora communication, RS485, IR Pport
3) Operate in both prepayment and post payment mode
4) Shut off the power if overload and credit exhausts
5) Adjustable power limit and low credit warning level
6)Anti-tamper detection and report.
Key benefits
a) easy to connection to user interface unit (UIU) for split type applications
b) Time of Use (TOU), multi-tariff, holiday setting
c) High accuracy
d) Recharge for the meter just by inputting a 20-digits Token code
e) Permanent storage of data in whole meter's life
