The Allen Bradley 1336F-BRF75-AA-EN-HCS1-L6 adjustable frequency AC drive is engineered for industrial use, specifically designed to handle a rated power output of 5.5 kW, equivalent to 7.5 HP. This model operates efficiently with a nominal efficiency of 97.5% when exposed to rated voltage and current.
It features an IP20 enclosure protection class, indicating it is suited for applications requiring moderate environmental protection. The A4 Frame series provides a robust structure for the drive. For input, it can handle a voltage range from 380 to 480 V AC (+/-10%) and 513 to 620 V DC, displaying versatility for various setups. Furthermore, it is compatible with three-phase input configurations, although single-phase usage will reduce output capacity to 50% for smaller frames.
Control capabilities include sine-coded PWM with an adjustable carrier frequency ranging from 2 to 8 kHz, while the base rating operates at 4 kHz. The drive also has a displacement power factor of 0.95, a standard feature for A4 frames, which enhances efficiency and power delivery.
A key feature of this drive is its sensorless vector control with auto-tuning, which allows it to maintain optimal motor performance. Additionally, it offers an intermittent overload capacity of 150% torque for constant loads and 115% for variable loads over one-minute durations. The configurable current limit ranges from 20% to 160% of the rated output current, allowing for precise control adjustments according to the application needs.
Acceleration and deceleration rates can be adjusted independently over dual times, with a resolution of 0.1 seconds up to a maximum of 3600 seconds, providing versatility in dynamic applications. The output frequency can also be programmed, ranging from 0 to 400 Hz.
