The Allen Bradley 1336F-BRF50-AF-EN-L4 is an adjustable frequency AC drive tailored for enhancing motor control in various applications. It supports an input voltage range of 380 to 480VAC or up to 620VDC, making it adaptable to different power systems. This drive delivers a continuous power output of 3.7 kW (or 5 HP) suitable for variable torque tasks.

Designed to withstand challenging conditions, the unit boasts an enclosure rating of IP65 (NEMA Type 4), providing excellent protection against dust and moisture. Its compact A3 frame supports a carrier frequency range between 2 and 10 kHz, ensuring efficient motor performance. Stability is maintained with the input undervoltage threshold set at a minimum of 280V AC, while an overvoltage protection system trips at 570V AC to safeguard internal components from damage.

The DC bus voltage typically reaches 648V under standard loading conditions, while the drive includes multi-stage overcurrent protection settings: soft trip at 160%, hard trip at 250%, and instantaneous trip at 300%. The IP65 enclosure's environmental operating range is specified from 0 to 40 degrees Celsius, enabling reliable functionality in typical operational environments.

Efficiency is a strong point, with the drive achieving a notable rating of 97.5% at its rated current and voltage. Control methods feature a programmable sine-coded PWM, allowing customizable voltage-to-frequency profiles. Additionally, it offers an adjustable output frequency range from zero up to 400 Hz, adaptable for diverse speed requirements.

For communication, the drive is compatible with Allen-Bradley PLCs via either Remote I/O or serial protocols, ensuring seamless integration into existing control frameworks.
