The Allen Bradley 1336F-CWF30-AN-IT is classified as a constant and variable torque drive, featuring a robust design suitable for diverse industrial applications. Operating with an input voltage range of 500 to 600 V AC in a three-phase configuration or at 775 V DC, this unit can handle a rated input current of 6.0 A. It efficiently utilizes its capabilities by providing both constant and variable torque outputs, each rated at 3 HP, while delivering a continuous power output of 2.2 kW.
Constructed without a protective enclosure, rated at IP00, the drive is tailored for environments where additional shielding is not necessary. The nominal DC bus voltage is set at 810 V DC, ensuring reliable performance in various applications. Additionally, critical monitoring is achieved with overvoltage trip settings at 690 V AC for inputs and 1,013 V DC for DC bus operations. Undervoltage conditions also trigger alarms, with thresholds at 343 V AC and 498 V DC, safeguarding equipment from damage.
This drive is designed to withstand transients, with the capability to tolerate voltage spikes of up to 6,000 V peak, per IEEE C62.41-1991 standards. It operates efficiently within a carrier frequency range of 2 to 6 kHz, with a preferred nominal setting at 4 kHz for C-Frame applications. The design of the 1336F-CWF30-AN-IT emphasizes performance and resilience, making it well-suited for effectively controlling a wide range of motor applications.
