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 of -25°C…+45°C. Another unique feature is the Imax of 45A.
The PRO1 series is available as a standard version (with a selectable S0 output) and also as a Modbus, M-bus or 2-tariff version. It can communicate and be programmed via an infra-red input. The different communication modes have over 40 variables like kWh, active and reactive energy, forward and reverse energy as well as Cos phi. The PRO1 smart energy meter is equipped with a resettable day counter and the total energy usage can be calculated via 5 different modes.
