Dissipating this heat may be impractical in applications with more frequent regeneration. In these applications, the higher cost of the Bonitron M3645 line regen as compared with resistive braking is quickly offset because the regenerated energy, which is returned to the AC line with near unity power factor, can be used to power other equipment. -
