Card Prepayment Single Phase Electric Meter , Surge Protection
Wireless Power Meter
The CA168-C is used for residential, light commercial and
industrial environments of prepayment metering applications. It is
a single phase two wire meter desgined in a compact BS footprint
mounting case, perfect for retrofitting installations using
exisiting wires. The meter is built with a surge varisotr for
lightening protection up to 13 kV and an SMPS for low voltage
operation down to 80V and below, making it uniquely catering to
unstable grid areas such as Africa and Central or South America
continents. Its wide range of current allowance 5(80) Amp and 30Vm
withstand of RF immunity makes it operatable in very severe
environments.
The CA168-C combines 3DES with STS encryption standard, using a
token card to transfer payment and customer information between the
head-end system (HES) and the meter. A consumer will top up his
electricity meter by visiting closest point of sale kiosk with the
card and make payment with the vendor. And the vendor will write
all the payment info into the card for the consumer to insert it
back into the meter to complete top up. Each card is unique to a
meter in the system and serves as a customer card at the same time.
This card prepayment feature provides the utility and service a
transparent and effecient mode of prepayment management. Payment
control parameters such as power limitation, emergency credit,
repayment policy, tariff plans can be set into the meter via card
contact, offering the utility or service providers flexible
contratual control.
The high profile of CA168-C is available with the option for
modular communication unit providing wireless communication such as
Power Line Carrier (PLC) Radio Frequency (RF) and GSM/ GPRS on
customers request. With this wireless feature, the meter can be
utilized for AMR AMI functions as in communication and interaction
with a head-end server (HES) for automatic meter readout, remote
disconnection and reconnection, tariff setting and upgrade, etc.
