1336S-BRF50-AN-EN5

The Allen Bradley 1336S-BRF50-AN-EN5 is a robust adjustable frequency AC drive, tailored for industrial applications where precise motor control is essential. It operates effectively within a voltage range of 380 to 480 volts AC or 513 to 620 volts DC, making it adaptable to varying electrical systems. This unit is rated for a motor output of 3.7 kW (5 HP), ensuring it can handle significant workloads.

When evaluating input current specifications, the drive operates at 10.0 A under constant torque conditions and 10.7 A for variable torque scenarios. This flexibility ensures users can achieve optimal performance based on their specific operational demands. The corresponding output current ratings are 8.4 A for constant torque and 9.0 A for variable torque, further attesting to its efficiency.

In terms of energy management, the input kVA ranges from 6.6 to 8.0 for constant torque and from 7.0 to 8.5 for variable torque. The output kVA is 6.7 for constant torque and 7.2 for variable torque. The efficiency rating at the rated load is an impressive 97.5%, ensuring high performance and reduced operational costs. Power factor performance typically sits at 0.80, with an option to enhance it to 0.95 using an inductor.

The drive is designed to withstand electrical anomalies, featuring a short circuit rating of 200,000 A rms symmetrical. It has defined trip voltages: overvoltage conditions trigger at 570 volts AC and undervoltage at 280 volts AC. For DC bus applications, the respective overvoltage and undervoltage trip points are set at 810 volts and 400 volts. The NEMA Type 1 enclosure, complemented by an IP20 rating, helps protect the internal components from dust and moisture, making it a reliable choice for a range of settings.
