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
