Evolution TRI-1 power supply (0.55-7.5 kW)

The Pedrollo EVOLUTION TRI-1 control panel is designed for three-phase submersible pumps with power ratings from 0.55 to 7.5 kW. It is a reliable electronic control solution housed in an IP55 self-extinguishing thermoplastic enclosure. The panel provides full pump management and protects it from overload, short circuit, and abnormal operating conditions, extending equipment lifespan.

Its key feature is the electronic board with cos φ monitoring, which enables detection of dry-running without the need for level sensors. The unit is ideal for 4" and 6" submersible well pumps.
