Brake Chopper Resistor

● When a drive unit is attempting to rapidly brake a motor “Deceleration Braking Cycle” or when an “overhauling load” condition exists, the spinning motor acts as a generator. This freewheeling condition will force some voltage back into the drive unit (regeneration) which, depending upon the amount of regeneration, may cause an overvoltage condition if the energy is not “dumped” somewhere else. An external dynamic braking resistor provides a compact, cost effective method of controlling the braking, absorbing the energy and dissipating this as energy as heat.
● ZENITHSUN DHY series High Power Wirewound Resistor has excellent performance when it is used as Dynamic Braking Resistor, for any application, with power ratings from a few watts up to many megawatts and with any duty cycle.
