Sonel MPI-540 Electrical Installation Meter (7" Screen, IP51)

The multifunctional Sonel MPI-540 meter is designed for measuring electrical installation parameters and logging power quality in 3-phase networks. The device features a 7-inch touchscreen and an IP51-rated enclosure.

The Sonel MPI-540 meter is a measuring instrument that combines the functions of a power quality analyzer and a shock protection testing device. The built-in 3-phase logger allows measuring parameters of 50/60 Hz power networks in class S according to the EN 61000-4-30 standard. The device enables commissioning measurements of installations, including fault loop impedance, RCD parameters, as well as insulation and earth resistance.

Key features

• Color 7-inch LCD touchscreen with a resolution of 800x480 pixels.
• 3-phase network parameter logger with voltage measurement up to 500 V and current up to 3 kA.
• Fault loop impedance measurement, also in circuits with RCDs without tripping them.
• Communication and data transfer via USB port, SD card, and Bluetooth and Wi-Fi modules.
• Powered by a dedicated Li-Ion battery.
