Calin's cutting-edge non-wired solution, the CA168-WS21, is a
single-phase prepaid electricity meter specifically engineered for
remote STS prepayment environments. This two-wire, 5(60) Amp (with
an 80A option), keypad-based smart electric meter is housed in a
compact BS5685 footprint case, making it an ideal choice for
residential, commercial, and light industrial applications in less
populated areas.
Manufactured under stringent ISO9001 standards, the CA168-WS21
features an IP54-rated protective class, ensuring durability and
resilience in challenging conditions. Its operational voltage range
spans from -40% to +20%, coupled with an enhanced RF immunity of
30V/m, enabling reliable performance even in harsh environments
characterized by brownouts, lightning strikes, and frequent voltage
dips.
The CA168-WS21 further distinguishes itself with a built-in GPRS
modem, facilitating seamless communication with the back-end server
via TCP/IP or VPN protocols. This feature enables periodic
automatic meter reading, conducted remotely from the server side.
Additionally, utility or service providers can effortlessly
configure meter settings through GSM networks, streamlining
operations and enhancing customer service.
In summary, the CA168-WS21 represents a compact and economical
solution for AMR AMI smart metering setups, integrating the
functionalities of a prepaid electricity meter, STS prepaid meter,
and smart electric meter into a single, robust package. Its
advanced features and robust construction make it an excellent
choice for remote prepayment environments, where reliability and
ease of use are paramount.
