VSD Braking Systems (Brake Units and Aluminium Housed Resistors)

Dynamic Braking Systems are used to dissipate energy (cheap and simple method) by converting regenerative energy into thermal energy (burn off energy). Smaller Drives include a built-in switch to divert extra power to a resistor, but for larger units without a built-in braking switch, external braking units are required. These systems can release the energy regenerated during Motor speed regulation (via brake resistance) to produce enough braking torque to ensure normal operation. These systems are popular for use in cable/wire drawing machines, cranes, elevators, production machinery, mine hoists, centrifugal and oil pumps in oil field, etc.

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 Drive from tripping.

*We stock Braking Units and Resistors for 3-Phase 380V model drives. Please enquire regarding pricing.
