The CA168-F is an advanced STS prepaid electricity meter, serving
as an anti-tampering single-phase smart electric meter, which is a
refined version of the original CA168 model. This compact device,
which aligns with the BS footprint for prepayment systems, operates
as a smart energy meter and a credit management tool with a
user-friendly keypad interface. It is designed to be cost-effective
while packed with features, accommodating various current ratings
(5(80)A) and boasting a 30Vm RF withstand immunity, suitable for
demanding environments. It is perfect for low-voltage metering in
residential and small commercial applications.
The meter features a robust metal backplate for secure mounting and
enhanced resistance to tampering. Its polycarbonate, fire-resistant
casing ensures durability in high-temperature conditions.
Manufactured in strict adherence to ISO9001 standards and utilizing
the STS encryption algorithm, this STS prepaid meter offers
utilities a secure and dependable solution for revenue protection
in the context of prepaid electricity services.
Key Features of the CA168-F STS Prepaid Electricity Meter:
a) Tamper Detection with Trip and Alarm: The meter is equipped to
detect and respond to tampering attempts, including cover openings,
reverse connections, and neutral disconnections, triggering
immediate trips and alarms.
b) Visual Indicators for Relay Status and Alerts: The display panel
latches to show the status of the relay, as well as any tampering
incidents and low credit warnings to alert users of critical meter
conditions.
c) Customizable Power Limit and Emergency Credit: Users can adjust
power limits and set up emergency credit options to manage
electricity usage according to their specific needs.
d) Bi-directional Measurement Capability: The meter supports
bi-directional measurement, accurately recording energy flow in
both directions, which is essential for net metering applications.
e) Comprehensive Meter Information Display: The meter provides a
clear display of valuable information including voltage (V),
current (A), power (P), and remaining balance, allowing users to
monitor their energy consumption in real-time.
f) Durable with IP 54 Rating: The CA168-F prepaid meter boasts an
IP 54 rating, ensuring it is dust-protected and splash-resistant,
making it suitable for a wide range of environmental conditions.
