Allen-Bradley Dynamic Braking Chopper with 380/415/460V AC rating and 750V DC continuous voltage.

Allen-Bradley’s 1336-WB110 Dynamic Brake Chopper Module is a 480V AC brake chopper module with a 2.5-ohm braking resistor.

It is used to increase braking torque from 10-100% to 1336% for Allen-Bradley 1336. 1336VT, 1336PLUSII, 1336FORCE, or 1336IMPACT inverters.

The Brake Chopper Module has a 200A, 700V AC, Ferraz Shawmut fuse with an SCR overvoltage crowbar circuit for inexpensive but effective overvoltage protection.

It also features an insulated gate bipolar transistor (IGBT) chopper transistor voltage control to effectively regulate the DC bus voltage during regeneration.

The 1336-WB110 has an operating voltage range of 380-480V AC and an operating current of 110A, which allows it to be used with another Allen-Bremse module in applications where the operating current exceeds the module’s rated current.

In applications where the operating current exceeds the module’s current rating, it can be set up in parallel with another Allen-Bradley brake chopper module in a master-slave configuration.

The 1336-WB110 has a heavy-duty rating of 460V AC drive voltage, 750V DC conduction input voltage from a DC bus power supply, and a 2.5 ohm dynamic braking value.

The 1336-WB110 has 12A, 30V DC, normally closed (N.C.) contacts with transistor-transistor loop compatibility.

Configured to close when power is applied to the terminal’s brake module and open in the event of a brake fault or power failure with an initial contact resistance of 100m ohms.

The 1336-WB110 has an operating temperature range of -10-40ºC (14-104ºF), will not derate in the non-condensing and non-corrosive humidity range of 5-95%.

It can be stored over a temperature range of -40-70ºC (-40-158ºF). It can be installed up to 1000 meters without derating.

Power dissipation is 100W at 190% duty cycle** and is encased in an IP00 (open) rated enclosure.

The 1336-WB110 weighs approximately 11.34 kg (25 lbs.), has overall dimensions of 290.6 mm x 239.8 mm x 304.8 mm (11.44 in. x 9.44 in. x 12 in.), and meets UL and c-UL standards.
