Main features

Improved braking torque:1336-WB110 can significantly increase braking torque from 10%to 100%to higher levels(although the specific percentage of improvement may vary depending on the application scenario,the product description mentions that it can significantly Improved braking performance).

Overvoltage Protection:The module is equipped with an SCR overvoltage crowbar circuit,which is a cheap but effective overvoltage protection mechanism.

Voltage Control:Features Insulated Gate Bipolar Transistor(IGBT)chopper transistor voltage control to effectively regulate the DC bus voltage during regeneration.

Parallel Configuration:The 1336-WB110 can be set up in parallel with another Allen-Bradley brake chopper module in a master-slave configuration.

Fault indication:Equipped with a fault indication function,it closes when the brake module is powered and opens when a brake fault or power failure occurs.

Application and Compatibility

Application scenarios:1336-WB110 is suitable for industrial applications that require dynamic braking,such as inverter-controlled motor systems.
