Limit Load Control Single Phase Watt Hour Meter IP54 Prepaid
Electricity Meters
The CA168-G is a newly upgraded smart single phase electric meter
that combines high precision metrology with wireless communication
and contractual control methods. It is a two wire spec that
operates in prepayment and post-payment mode. The meter can change
payment mode upon the receipt of the command transmitted from
head-end server. The meter displays full set of metering data
including V, A, PF, total consumption, balance and last 5
successfully entered tokens. It also records load profiling data at
preset interval periods. This meter is superb choice for large
residential consumer and light commercial or industrial users'
metering applications.
The meter is compliant with Standard Transfer Specification (STS)
and designed for STS credit dispensing. It operates in currency
value and kWh credit and offers both service providers and
consumers added convenience by seeing the balance immediately. The
curency value based algorithm allows the meter to work on Time of
Use (TOU) tariff basis and enables the utility to increase their
revenue and as the same time manage their load effciently.
The GSM wireless connectivity makes CA168-g availabe for real-time
data transmission to the head-end server and remote auditing as
well as control by the utility. This feature offers service
providers flexibility of effcient management with no need to pay
extra to set up extra equipment to collect data and comminicate
with the meter..
