2.3 ABOUT THE DBW03

The DBW03 dynamic braking module is used in applications with high-inertia loads,
requiring short braking times. It is also used in lifting applications that require speed
control of the load. In these cases, the power flows from the line to the motor while
it is motorizing, see figure 2.1.
