1336F-B020-AN-EN-LA4-L6E

The Allen-Bradley 1336F-B020-AN-EN-LA4-L6E 1336 PLUS II series drive is an AC-powered adjustable frequency drive. In response to feedback from a connected motor, it can change its output frequency in order to control the connected motor’s speed. The supported output frequency range of the drive is 0 to 400 Hertz. The nominal output power rating of the 1336F-B020-AN-EN-LA4-L6E drive is 20 Horsepower for constant torque applications and 25 Horsepower for variable torque applications. The input drive is designed for operating at AC voltages ranging from 380 to 480 Volts AC with +/-10% tolerance. The range of tolerated input frequencies is 47 to 63 Hertz. The 1336F-B020-AN-EN-LA4-L6E drive trips at 570 Volts AC input for overvoltage and at 280 Volts AC input for undervoltage. Its nominal bus voltage rating is 648 Volts DC. The drive trips at 810 Volts DC bus overvoltage and at 400 Volts DC bus undervoltage.

The technicians working on the Allen-Bradley 1336F-B020-AN-EN-LA4-L6E 1336 PLUS II series adjustable frequency drive should ensure that the bus capacitors are discharged completely before beginning any maintenance work. Failure to discharge the bus capacitors completely can lead to electric shock. The DC bus voltage can be measured on the test points provided on the drive’s TB1 terminal block, and this voltage rating must be 0.0 Volts DC before any work is begun on the drive. The 1336F-B020-AN-EN-LA4-L6E drive features a 115 Volts AC rated control interface with encoder feedback. It also has an analog I/O module that supports one configurable input and one configurable output. The 1336F-B020-AN-EN-LA4-L6E drive is available in an open IP 00-rated enclosure that is designed for an ambient operating temperature range of 0 to 50 degrees Celsius. This drive contains components that are ESD-sensitive and the technicians who work on the drive must follow ESD precautions to protect the drive.
