Compact soft starters offer a variety of intelligent features

The compact S811+ is suitable for use with or without an enclosure for pump, fan and conveyor belt applications. It has an intuitive user interface with a special copy-and-paste keypad on the removable operator panel.

This function simplifies installation and saves time during maintenance work. It has an easy to use Digital Interface Module (DIM) that allows the user to configure the device and to read system parameters and monitor system values.

Monitoring functions include power, power factor, phase currents, phase voltage, device temperature, and more, saving additional measurement equipment and wiring cost. The S811+ also offers native Modbus RTU and quick change connections with external EtherNet IP/Modbus TCP communication modules. Configurable warning messages help to prevent unwanted motor tripping.

An optional Eaton-specific pump algorithm for the S811+ also suppresses unwanted ‘water hammer’.

The overload protection of the S811+ prevents device damage both to the motor and soft starter, whether used in normal operation or in a faulty application, protecting against overloads, motor blocking, motor stalling, phase loss or unbalanced loads.
