The 1336F-B250-AE-EN from Allen Bradley provides precise control as an AC adjustable-frequency drive. It operates within a voltage supply of 380 to 480 V AC, specifically designed for 3-phase systems. With a remarkable rated output power of 187 kW (or 250 HP), this drive is well-suited for high-demand applications requiring reliable performance.

Engineered with an IP 20 enclosure rating, the drive complies with NEMA Type 1 specifications, making it apt for typical indoor settings. Power management is particularly efficient, managing constant-torque inputs ranging from 212 to 268 kVA, while the output remains steady at 259 kVA. The variable-torque operations mirror these power capabilities, allowing for adaptable performance as per application needs.

Concerning safety, the drive is equipped with overvoltage and undervoltage trip functionalities. Specifically, overvoltage trips occur at 570 V AC and 810 V DC, while undervoltage settings trigger at 280 V AC and 400 V DC. In terms of current limits, configurable settings allow for variations across soft start (SW), hard wiring (HW), and instantaneous (Inst) limits of the variable torque operation.

Control is facilitated through a pulse width modulation (PWM) technique with sine-coded methods, accommodating carrier frequencies in the range of 2 to 6 kHz. Moreover, the drive boasts an adjustable output frequency capability spanning from 0 to 400 Hz, thereby providing sufficient flexibility for various motor applications. Compliance with electromagnetic compatibility (EMC) standards is assured due to the built-in filter included as standard, enhancing operational integrity.
