48v 500a PM DC Motor Controller With Regen

  PM programmable permanent magnet motor controllers provide efficient, smooth and quite controls for electrical vehicles like golf cart, go-cart, electric motorcycle, scooter, fork lift, hybrid vehicle, as well as electric boat and industry motor speed control. Motor speed controller uses high power MOSFET, PWM to achieve efficiency 97% in most cases. Powerful microprocessor brings in comprehensive and precise control to brushed motor controllers. This programmable permanent magnet motor controller also allows users to set parameters, conduct tests, and obtain diagnostic information quickly and easily. Kelly PM full bridge or 4 quadrant motor controller provides fast and reliable electronic direction control.
