Split Type STS Single Phase Electric Meter , Plc G3 Rf Din Rail
Power Meter
The CA168-S is a 35 mm Din Rail mounting keypad based single phase
prepayment electric meter.
The meter works with a broad range of current 5(80)Amp and voltage
-60%~ +30% V and the rugged RF withstand of 30 Vm. It is ideal for
submetering and retrofitting installations in very harsh
environments.
The CA168 -S consists of two parts. A customer interface unit
(CIU), and a main meter, metering and control unit (MCU). The CIU
is a keypad based display, to be installed within consumers homes
wherever there is a plug point. The MCU is the main meter,
installed away from consumer's home in a kiosk pavement, meter box
or a pole-mounted enclosure .Prepayment encryption decryption,
critical metering only happens with MCU and CIU is just for the
consumer to punch in token code and toggle information displays.
MCU communicates with CIU via wireless communication such as Power
Line Carrier (PLC), Radio Frequency(RF), and LoRa. This feature
allows for easy inspection by utility and service providers at any
time without visiting consumers' houses and reduces the chance of
tampering.
The communication features allows the meter to speak with a
back-end server in two way communication mode. A utility can do
remote readout, block / unblock meters, tariff setting, emergency
credit input, etc.
Major Features
1) Unidirectional measurement for reverse energy (SRE)
2) STS compliant
3) Disconnects on no credit or preset balance
4) Disconnects on tamper detected
5) Meter allows setting for power limit, emergency credit, debt
collection, surchages, etc
6) Anti-fraud features
7) Multi-rate and usage registered as Time of Use (TOU)
User Benefits
a) Quick and easy to install
b) Slim-line space saving design
c) Low operational and inventory cost
d) Two way communication with AMR AMI server(on request)
e) Flexible payment control through various element settings
f) Meter provides information by inputting short codes
