The Lovato 31RC3548 is a special rate controller designed to limit the rising current in AC electrical systems. It is designed to be installed in the main AC line of an electrical system, allowing the user to adjust current in the highest possible ranges. This allows users to adjust their current consumption according to the load requirements. The 31RC3548 has a wide range of setpoints as well as a choice of digital or analog inputs, digital outputs, and a relay output. This device is suitable for controlling resistive, inductive, or capacitive loads. It can also be used in applications where higher accuracy is required such as for motors with proportional speed control.
