Power Efficiency&＃039;s Motor Efficiency Controller is a solid state motor controller desinged to dynamically optimize the efficiency of single and 3 phase motors. In constant speed variable load applications, our patented E-Save Technology provides precisely the right amount of power to meet the demands of your application. In numerous tests, performed by independent third parties, the Motor Efficiency Controller has proven to save up to 40% of the energy normally used in appropriate applications. The reduction in electricity can instantly reduce your carbon footprint and may qualify for a utility rebate. Our motor controller integrates soft start functionality to provide a smooth acceleration of the motor to normal operating speed. It also incorporates electronic overload protection to protect your valuable assets. Since the Motor Efficiency Controller provides only the voltage and current required for the application, it reduces the operating temperature of the motor and thereby extending its useful life. Another benefit of the soft start functionality is reduced stresses on the mechanical system which reduces costly maintenance expenses. Designed for out of the box installation and operation, the Motor Efficiency Controller is easily configured for your application and can be installed quickly - allowing you more time to focus on other demands.
