DURApulse - GS4 Braking Options (Braking Units & Resistors)

When a variable frequency drive decelerates an AC motor, especially one with a large inertial load attached, a braking resistor may be required to help dissipate the energy. Larger GS4 DURApulse series AC drives ( approx. 30 hp and above) also require that dynamic braking units be used in conjunction with the appropriate braking resistors.
