Generally used for industrial applications where quick stopping is required which could cause the DC bus voltage to rise (over voltage). It is thus required where the regenerated energy needs to be dissipated quickly to manage the DC bus voltage to prevent the VSD from tripping.
For VSDs of more than 22kW a Brake Unit will also be required – please see https://www.emheater.co.za/blog-emheater-productrange-dynamicbrakingsystems/
