Technical Description

The Battery-Powered Remote Terminal Unit (RTU) is an intelligent device that enables data acquisition, remote transmission, analytical processing, and threshold-based alarm generation over 4G, 5G, and NB-IoT networks. Featuring ultra-low power consumption and an IP68-rated waterproof design, it is particularly well-suited for monitoring sites with no external power supply and stringent waterproof and dustproof requirements. Combination with rechargeable batteries and solar panels are available.

Since its first launch in 2007, and through continuous innovation and adaptation to evolving communication technologies, the Welletronics Battery-Powered RTU series has expanded to four product lines, meeting a wide range of application needs.
