The Allen Bradley 1336F-BP250-AN-EN-CM variable frequency drive (VFD) is engineered for high-performance applications requiring precision control. It has an output power capability of 187 kW, equivalent to 250 HP in variable torque mode. The unit can accommodate a supply voltage ranging from 380 to 480 V AC, allowing ±10% variance to adapt to different operational setups.
Designed without an enclosure (IP00), it operates as an open chassis model, facilitating efficient cooling. The compatible input current spans from 212 to 268 kVA, typically settling at 259 A nominally. For additional flexibility, the drive supports a maximum continuous output current of 325 A.
Protection features include an overvoltage trip at 570 V AC and 810 V DC, as well as undervoltage cutoffs at 280 V for AC and 400 V for the DC bus. Experience a 97.5% efficiency at rated load along with a power factor of 0.95 when operated without an external inductor.
This drive allows for frequency adjustments between 0 to 400 Hz with a precision of ±0.01%. In variable torque mode, it supports an overload capability of 115% current for up to one minute. The ambient operating limits range from 0 to 50°C, while it can handle humidity levels from 5 to 95% without condensation. The inclusion of a built-in common-mode choke (identified by the –CM option) enhances performance, making this VFD suitable for the rigorous demands of various industrial environments.
