The 1336F-BRF30-AE-EN-L6 from Allen Bradley represents an advanced variable frequency drive (VFD). It delivers a rated power of 2.2 kW (3 HP) when working with variable torque loads, achieving up to 3 HP for applications demanding constant torque. This drive supports an input voltage range of 380 to 480V AC or an alternative of 513 to 620V DC while functioning efficiently within three-phase systems.
The device's design meets IP20 (NEMA Type 1) enclosure standards, ensuring it operates under various conditions with EMC compliance. Its output current ratings are 5.3 Amps under constant torque and 6.0 Amps under variable torque at a voltage of 480V. Overload capabilities reach 150% for a minute under constant torque and 115% under variable torque, providing enhanced flexibility in dynamic loads.
Users can expect an output frequency range of 0 to 400 Hz, with precise accuracy of ±0.01% for digital control and ±0.4% for analog signals. Key protective features include safeguards against overvoltage (570V AC), undervoltage (280V AC), short circuits, and ground faults, ensuring reliable operation in various scenarios.
Communication is versatile, supporting protocols such as DeviceNet, Remote I/O, and RS232/422/485, allowing the unit to fit easily into broader automated systems. The cooling method employed is convection, suitable for an ambient range of 0 to 40 degrees Celsius as per the IP20 rating. With an efficiency rating of 97.5% at rated load, this drive exemplifies energy efficiency in motor control applications.
Optional dynamic brake kits, like the -KB005 for 380-480V models, enhance braking capabilities, and the analog I/O features a flexible configuration of 0-10V or 0-20mA inputs, complemented by isolated outputs via additional optional cards. For motor control, users have the flexibility to select between sensorless vector or V/Hz modes, allowing for a wide 120:1 speed range.
