The 1336-WB110 Dynamic Brake Chopper Module by Allen-Bradley is a 480V AC Brake Chopper Module with a 2.5 Ohms Brake Resistor used for increasing the braking torque from 10-100%, for the Allen-Bradley 1336, 1336VT, 1336PLUS, 1336PLUSII, 1336FORCE, or 1336IMPACT Frequency Drives. The Brake Chopper Module features a 200A, 700V AC, Ferraz Shawmut fuse, with an SCR over-voltage crowbar circuit to provide cheap but effective over-voltage protection, and it also features an Insulated Gate Bipolar Transistor (IGBT) Chopper transistor voltage control which efficiently regulates DC bus voltage during regeneration. The 1336-WB110 has an operating voltage range of 380-480V AC, with 110A operational current, and it can be set in parallel in a master-follower configuration with another Allen-Bradley Brake Chopper Module in an application with an operating current exceeding the module’s current rating. The 1336-WB110 has heavy-duty ratings of 460V AC drive voltage, with 750V DC turn-on input voltage from a DC Bus supply, and a 2.5 Ohms Dynamic Brake value.

The 1336-WB110 has 12A, 30V DC, Normally Closed (N.C.) contact with Transistor-Transistor Loop compatibility, which is configured to close when power is supplied to the terminal’s brake module, and which opens when a brake fault or power loss occurs, and with an initial contact resistance of 100m Ohms. The 1336-WB110 has an operating temperature range of -10-40ºC (14-104ºF), without de-rating, at a 5-95% non-condensing and non-corrosive humidity range, and it is stored at a -40-70ºC (-40-158ºF) temperature range. Its maximum installation height is 1000m without de-rating, with 190W of maximum power dissipation at 100% duty cycle, and it is enclosed in an IP00 (open)-rated enclosure. The 1336-WB110 weighs about 11.34kg (25lbs), with overall dimensions of 290.6mm x 239.8mm x 304.8mm (11.44in x 9.44in x 12in), and it is UL and c-UL Listed with CE compliance.
