Description

Product Overview

The Allen‑Bradley 1336-MOD-KB010 is a complete dynamic braking module kit designed for Bulletin 1336 series variable frequency drives. It integrates power switching hardware and high-power braking resistors to dissipate regenerative DC bus energy generated by overhauling loads during rapid deceleration or emergency stop events. This unit prevents overvoltage faults that can trip the drive and damage internal power semiconductors, delivering up to 100% motor braking torque for 20 seconds at a typical 20% duty cycle. Automation technicians and plant reliability teams rely on this module to add heavy-duty braking capability to legacy 1336 IMPACT and PLUS II drives. The enclosed NEMA Type 1 housing protects resistive elements from dust and accidental contact, while built-in forced-air cooling maintains stable thermal performance during repeated braking cycles.

Application Scenarios

• Loaded Bulk Conveyor Emergency Stop: This dynamic brake module absorbs regenerative energy from heavy loaded conveyors. The 1336-MOD-KB010 enables fast controlled stopping without DC bus overvoltage trips, reducing belt slip and mechanical shock during safety stop sequences.
• Centrifugal Fan and Blower Rapid Shutdown: Installed with 1336 drives for large high-inertia fans, the module safely dissipates rotational energy during emergency shutdowns. It protects drive power electronics from voltage spikes generated by spinning fan inertia.
• Material Handling Hoist Auxiliary Drive Control: The brake module handles overhauling load conditions on hoist and lifting equipment. It maintains stable speed control during load lowering and prevents uncontrolled coasting and drive overvoltage faults.
