The adjustable frequency AC drive model 1336F-BRF15-AN-IT by Allen Bradley operates within an input voltage range of 380 to 480 volts AC across a 3-phase setup. This unit excels in performance, offering a constant torque power rating of 1.5 HP (1.2 kW) while also providing a variable torque rating of 1.2 kW. Current output ratings are specified at 2.8 A for constant torque applications and 3.0 A for variable torque applications.
Designed with an open chassis, the drive holds an IP00 enclosure rating, making it suitable for environments where dust or moisture exposure is limited. Its input frequency tolerance spans from 48 to 62 Hz, while the output frequency range is versatile, extending from 0 to 400 Hz. The drive boasts an impressive overload capacity, rated at 150% for constant torque applications and 115% for variable torque applications, with a sustained period of 60 seconds for each rating.
Efficiency standards are notably high at 97.50%, providing reliable performance over prolonged use. The control algorithm integrated into this model utilizes sensorless vector pulse-width modulation (PWM), optimizing the operation of connected motors. It also features a power factor of 0.80, which can improve to 0.95 when an inductor is used in conjunction. Operating temperature conditions for this drive range from 0°C to 50°C (32°F to 122°F), ensuring it functions effectively across a broad spectrum of industrial applications.
