The Allen Bradley 1336F-BRF15-AF-EN is engineered as a constant and variable-torque drive, suitable for demanding industrial environments. This model operates within an AC input voltage range of 380 to 480 VAC in a three-phase configuration. It effectively processes a DC bus voltage ranging from 513 to 620 VDC to support various motors.
The continuous output currents are rated at 2.8 Amperes for constant torque applications and 3.0 Amperes for variable torque functions. The drive provides an ingress protection rating of IP 65, ensuring it is safeguarded from harsh conditions including dust and moisture. Additionally, the apparent input power spans from 2.2 to 2.6 kVA for constant torque and 2.8 to 3.3 kVA for variable torque operations. The output apparent power is rated at 2.2 kVA at 2.8 A for constant torque and 2.4 kVA at 3.0 A for variable torque.
This drive allows for an adjustable carrier frequency ranging from 2 to 6 kHz. The line ride-through capability is 15 ms at full load, while the logic ride-through can last for a minimum of 0.5 seconds, ensuring operation stability.
Protection mechanisms are included, with over and undervoltage trip settings established between 280 and 570 VAC for AC input and 400 to 810 VDC for the DC levels. It also features a programmable overcurrent limit between 20 and 160%, with hardware limits ranging from 180 to 250%.
This unit is designed to endure short-circuit conditions up to 200 kA symmetrical at 600 VAC, and functions efficiently in ambient temperatures from 0 to 40 °C. For installations, the drive’s maximum operational altitude reaches up to 1000 meters without necessitating derating, making it a reliable choice for various applications.
