1336S-BRF75-AA-EN

The 1336S-BRF75-AA-EN is an adjustable frequency AC drive from Allen Bradley's 1336 PLUS Drives series. It incorporates sine-coded PWM as its control topology, which allows for effective modulation of motor power. Designed for flexibility, this unit can operate using either sensorless vector control or Voltage/Hz methods. It supports input voltages ranging from 380 to 480 VAC, or direct current between 513 and 620 VDC. This drive offers a rated power output of 5.5 kW, equivalent to 7.5 HP, suitable for a variety of induction motors.

This drive provides precise control with a constant torque output of 14.0 A and a corresponding power of 11.2 kVA. For applications requiring variable torque, the drive supports up to 17.5 A and 13.9 kVA. The input current can vary from 14.5 to 18.5 A, ensuring compatibility with a wide range of motor loads. The output frequency of the drive spans from 0 to 400 Hz, accommodating different operational speeds.

Notably, it features dual ramp acceleration and deceleration settings with a duration ranging from 0 to 3600 seconds, allowing for smooth transitions during operation. The unit also includes a current limit that can be adjusted to between 20% to 160% of its rated capacity, enhancing its adaptability to varying workloads. It has a robust short circuit rating of 200,000 A at 600 V and overload capabilities, supporting constant torque up to 150% for one minute and variable torque up to 115% for one minute. Furthermore, this drive achieves an impressive efficiency rating of 97.5% under rated load conditions.
