Allen-Bradley 336-WB0091 Dynamic Braking Chopper Module

Description:

The Allen-Bradley 1336-WB009 Bulletin Braking Chopper is a dynamic braking chopper module used with Bulletin 1336 series AC drives to dissipate regenerative energy during motor deceleration. Commonly installed in Allen-Bradley 1336 PLUS, 1336 PLUS II, 1336 FORCE, and 1336 IMPACT drives where controlled braking and DC bus voltage regulation are required. Maintenance teams, OEMs, and system integrators use this module for drive repairs, retrofit projects, and restoration of legacy variable frequency drive systems.

Applications:

The Allen-Bradley 1336-WB009 Bulletin Braking Chopper is commonly used in conveyors, cranes, centrifuges, fans, pumps, and other industrial machinery utilizing Allen-Bradley 1336 series AC drives. The 1336-WB009 configuration absorbs regenerative energy generated during motor braking and dissipates it through an external dynamic brake resistor, helping reduce stopping time and prevent DC bus overvoltage conditions.
