The 1336F-BX040-AN-IT by Allen Bradley represents a powerful solution in the realm of AC variable-frequency drives. This versatile unit is intended for input voltages ranging from 380 to 480 VAC with an allowable fluctuation of ±10%. It can sustain a maximum output current of 59 Amps when engaged in constant-torque scenarios. The drive's output power can reach 40 horsepower for constant-torque applications and 30 horsepower for variable-torque needs, making it suitable for various driven machinery.
Operating within an output frequency spectrum from 0 to 400 Hz provides user adaptability in different operational contexts. The drive employs a carrier frequency configuration of 2 to 6 kHz, with 2 kHz set as the default value for standard operations. It is engineered to handle overload conditions of up to 150% for one minute in constant-torque use and 115% in variable-torque applications, thus ensuring reliability under peak demands.
In terms of environmental tolerance, the device functions efficiently in ambient temperatures of 0 °C to 40 °C and can be stored at temperatures from –40 °C to 70 °C. At full load conditions, it maintains a DC bus ride-through capability of 15 milliseconds, allowing it to keep operating seamlessly in brief power interruptions.
Enhancements like a 2×16 character backlit LCD provide a clear local display for easy monitoring and control. Additionally, the drive offers an efficiency rating nearing 97.5% at full load, contributing to energy savings in various applications.
