1336F-B020-AN-EN-L8E

The Allen-Bradley 1336F-B020-AN-EN-L8E drive is a variable frequency drive from the 1336 PLUS II drive series. It is known as a “variable frequency drive” because its output frequency rating can be adjusted in order to control the speed and torque of a motor. The range of output frequencies supported by the 1336F-B020-AN-EN-L8E drive is from 0 to 400 Hertz. The control interface that is installed on the 1336F-B020-AN-EN-L8E drive operates with a voltage rating of 24 Volts AC/DC and it supports encoder feedback for use with encoder loss detection functions. The 1336F-B020-AN-EN-L8E variable frequency drive’s 3-phase input voltage rating is 380 to 480 Volts AC at 50/60 Hertz frequency. It is possible to use single-phase AC input voltage too, but this will lead to 50% output derating.

The full output rating for the Allen-Bradley 1336F-B020-AN-EN-L8E variable frequency drive 1336 PLUS II series with constant torque and 3-phase input voltage is 20 Horsepower, and the full output rating for the drive with variable torque and 3-phase input voltage is 25 Horsepower. For constant torque, the input current rating is 32 Amps and the output current rating is 31 Amps while for variable torque, the input current rating is 34 Amps and the output current rating is 34 Amps. An optional input circuit breaker for input protection can have a maximum current rating of 125 Amps, and an optional input fuse can have a maximum current rating of 125 Amps. Allen-Bradley also recommends using a 50 Amps-rated motor circuit protector. The language option available on the 1336F-B020-AN-EN-L8E drive is English. The drive enclosure is open and belongs to the IP 00 protection class. The operating temperature range of the drive is 32 to 122 degrees Fahrenheit. Only trained professionals should handle, install, operate, and maintain the drive for safety.
