A smart single-phase direct-measurement energy meter supporting communication via Modbus protocol.
The product is also available as a variant: Single-phase energy meter KLEFR 6914 for direct energy. It is an identical product, it differs only in the logo.
The PRO1 Series is a range of 1 module, single-phase Smart Energy Meters consisting of 4 different types, each with their specific characteristics. They have an exceptional combination of a high accuracy class (1/B) and a broad temperature range from -25 °C to +45 °C. Another unique feature is the Imax of 45 A.
The Modbus protocol is used for communication with the PRO1-Mod meter, through which it is also possible to set most parameters. The infrared port (with a wavelength of 900 – 1 000 nm) enables full programming of the energy meter.
