1336F-B020-AN-EN-LA1-L5

The Allen-Bradley 1336F-B020-AN-EN-LA1-L5 1336 PLUS II series drive is an adjustable frequency drive. It is designed for direct connection to 3-phase AC power supplies that allow it to operate at its full output power ratings. The input voltage range for the drive is from 380 to 480 Volts AC. The drive can operate with constant or variable torque. The full rated output power of the drive is 20 Horsepower for operation in the constant torque mode, the input current rating for constant torque operation is 32 Amps, and the constant torque mode output current rating is 31 Amps. The full rated output power for variable torque mode is 25 Horsepower, the input current rating for variable torque is 35 Amps, and the output current rating for famriable torque is 34 Amps. The 1336F-B020-AN-EN-LA1-L5 drive does not support built-in input short-circuit protection. However, a circuit breaker or a fuse can be installed to protect the drive from input short-circuits. A motor circuit protection device can also be used at the drive output to protect the connected motor from excessively high currents.

The Allen-Bradley 1336F-B020-AN-EN-LA1-L5 1336 PLUS II series adjustable frequency drive maintains its required ambient temperature during operation via natural convection cooling. It is also supplied with a heatsink for improved heat dissipation. The total heat dissipation rating of the drive system is 768 Watts. Proper ventilation is also a prerequisite for proper heat dissipation, and proper ventilation requires appropriate inter-device separation. The minimum horizontal spacing between adjacent drives that is recommended by Allen-Bradley is 4 inches, and the minimum recommended vertical spacing between drives is 6 inches. The 1336F-B020-AN-EN-LA1-L5 drive’s operating temperature range is 0 to 50 degrees Celsius. The recommended storage temperature range is -40 to 70 degrees Celsius. The IP 00 rated enclosure of the drive is open and it is not waterproof or dustproof. The control interface on the drive operates 24 Volts AC/DC. It also has an analog I/O interface with 1 single-ended and non-isolated configurable input and 2 single-ended and non-isolated outputs.
