1336S-BRF75-AN-EN4-HAB

The Allen Bradley 1336S-BRF75-AN-EN4-HAB adjustable frequency drive is tailored for robust industrial applications. Supporting an input voltage range of 380 to 480 volts AC or 513 to 620 volts DC, this device accommodates various system requirements. It employs a sine-coded PWM control topology that allows for fine-tuning of the carrier frequency, enhancing performance in different settings.

Motor control capabilities include sensorless vector and V/Hz modes, catering to various operational needs. The output frequency is adjustable between 0 to 400 Hz, providing flexibility in speed control. Frequency precision is notably high, with digital accuracy at ±0.01% and analog at ±0.4%. The unit is equipped with dual independent ramps for acceleration and deceleration, which can range from 0 to 3600 seconds.

This drive delivers a motor power output of 5.5 kW, which is equivalent to 7.5 HP. The unit features an IP20 (Type 1) enclosure, accompanied by a blank Human Interface Module (HIM) cover, ensuring protection from environmental factors.

Current ratings for constant torque are noted at 14.5 A input and 14.0 A output, with associated kilovolt-amps input ranging between 9.5 to 11.6 kVA. Conversely, variable torque ratings are 18.5 A input and 17.5 A output, paired with kilovolt-amps input from 12.2 to 14.7 kVA.

Electrical efficiency is excellent, rated at 97.5% during full load conditions, which contributes to energy savings. The drive is designed to withstand short circuits of up to 200,000 A RMS symmetrical at 600 V, enhancing reliability in demanding situations. Overloading is supported at 150% for 60 seconds under constant torque conditions and 115% for variable torque scenarios. Additionally, an adjustable current limit ranges from 20% to 160% of the rated output, providing further operational flexibility.
