1336S-BRF75-AA-ES4

The Allen Bradley 1336S-BRF75-AA-ES4 serves as an advanced AC adjustable frequency drive, suitable for managing a variety of motor applications. This model is capable of supporting sine-coded PWM, sensorless vector, or V/Hz control strategies, allowing for flexible operation in diverse environments. The drive operates within a voltage input range of 380 to 480 volts AC or 513 to 620 volts DC with a tolerance of ±10%.

It has a power rating of 5.5 kW, equivalent to 7.5 HP, making it robust enough for multiple operational demands. The output frequency can be adjusted from 0 to 400 Hz, which is ideal for precise motor speed control. Current ratings are also noteworthy, with a variable torque output of 17.5 A and a constant torque output of 14 A, which positions this drive to handle various load conditions effectively.

Control frequency ranges from 48 to 62 Hz, ensuring compatibility with many electrical systems. The overload capacity allows for 150% constant torque for 60 seconds and 115% variable torque for the same duration, providing necessary flexibility during peak operational demands. The adjustable current limit spans from 20% to 160%, further enhancing the drive's adaptability by allowing fine adjustments to the proportional and integral gains of the system.

Furthermore, the 1336S-BRF75-AA-ES4 accommodates dual acceleration and deceleration ramps that can be set between 0 and 3600 seconds, providing enhanced control over motor dynamics. The power factor rating is noted at 0.8, with the potential to reach up to 0.95 when utilizing an optional inductor or larger frame. Lastly, this model boasts a short circuit rating of 200,000 A rms symmetrical with a maximum of 600 V, solidifying its reliability against electrical faults.
