Industrial B100-DB-001 Dynamic Braking Module

Description:

The Thor B100 DB Dynamic Braking Module is used in AC variable frequency drive (VFD) systems to provide controlled dynamic braking for three-phase AC motors by dissipating regenerated energy during deceleration. Commonly installed in industrial conveyors, cranes, hoists, machine tools, packaging equipment, and material handling systems using 480 VAC drives with motors rated from 7.5 to 37.5 HP. Maintenance technicians and automation engineers use this dynamic braking module for drive repair, system upgrades, and replacement of failed braking assemblies to improve stopping performance and protect drive components.

Applications:

The Thor B100 DB Dynamic Braking Module is designed to work with compatible AC vector drives by switching regenerative energy to an external braking resistor during motor deceleration. This enables faster stopping times, reduces overvoltage faults on the DC bus, and improves braking performance in applications with high inertia or frequent start-stop cycles, making it suitable for manufacturing, material handling, and industrial automation systems.
