1336E-B250-AE-EN-HA2-L4

The Allen Bradley 1336E-B250-AE-EN-HA2-L4 is engineered as an advanced AC Variable Frequency Drive (VFD) for precise control over motor operations. Rated for an input voltage of 380 to 480 volts AC, this drive functions efficiently in three-phase configurations and accommodates a nominal horsepower rating of 250 HP. For applications requiring a reduced capacity, the drive supports a derated horsepower of 187 HP.

This unit is designed with an enclosure rated IP 20 / NEMA Type 1, which is suitable for standard indoor installations. Its input power range spans from 2 kVA to 437 kVA at 380V and up to 555 kVA at 460V, providing flexibility for various usage scenarios. The drive operates at input frequency settings of both 50 Hz and 60 Hz, with a permissible variation of ±3 Hz.

The output capabilities include a broad current range from 2.5 to 983 Amps, along with an output horsepower spectrum that varies from 7.5 to 800 HP in continuous mode. This unit supports significant overload conditions, allowing for 100% continuous current operation and a 150% rating for one minute under constant torque conditions.

An adjustable output frequency capability between 0 and 250 Hertz enhances its adaptability to various motor speeds. When equipped with an encoder, the speed regulation achieves an impressive accuracy of 0.001% in a 100:1 range and 0.02% in a 1000:1 range. In scenarios without an encoder, it maintains a speed regulation accuracy of ±0.5% across a 120:1 speed range.

Torque regulation is also efficient, with ±2% accuracy when using an encoder and ±5% in sensorless configurations. The Allen Bradley 1336E-B250-AE-EN-HA2-L4 VFD is designed to provide robust and accurate performance, making it suitable for demanding motor control applications.
