FAQ
Why Do RVs Need LoRaWAN Electricity Meters?
LoRaWAN, a low-power wide-area network technology, is particularly well-suited for long-range, low-power IoT applications. In RVs, which are mobile and have limited power supplies, LoRaWAN electricity meters like EM114039-01 and EM114039-02 offer unique advantages that effectively address various challenges in RV power management.
Why External CT Connected DIN Rail Meters?
While ordinary DIN rail three-phase meters are suitable for many applications, external CT connected DIN rail meters offer significant advantages in terms of flexibility, accuracy, and safety.
