        Major Tech MTS21 | 65A Smart Energy Meter & Timer | WiFi & Bluetooth

        The Major Tech MTS21 is a high-precision smart energy meter for single-phase 2-wire systems, built for real-time tracking and smart control of electrical loads. It displays Voltage, Current, Active Power, Frequency, and Power Factor locally on its LCD, and remotely via the Major Tech Hub app.

        With a 65A / 9600W rating, it’s ideal for residential, commercial, or light industrial use. It also features automated load protection, instantly shutting off power during overcurrent or over/under voltage events (up to 450V spikes). The dual connectivity - Wi-Fi and Bluetooth - ensures continuous operation and control even during network dropouts.

        The built-in logger stores up to 2 months of energy data, exportable in Excel format for reporting. Designed for fast install with 35mm DIN rail compatibility, the MTS21 helps optimise energy use and safeguard connected loads.
