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.
