1336S-B250-AN-EN4

The Allen Bradley 1336S-B250-AN-EN4 AC drive is engineered for demanding applications where high performance is essential. It has an apparent power output capability of 259 kVA, which ensures adequate power delivery for a wide range of motor-driven tasks. This drive can handle an input current of 322 A and an output current of 325 A, enabling it to efficiently manage significant loads.

Designed to operate with a rated voltage of 380 to 480 V AC in three-phase configurations, the 1336S-B250-AN-EN4 can deliver up to 187 kW (250 HP) of motor power, meeting the needs of heavy machinery and complex processes. The nominal DC bus voltage for the drive is specified at 648V DC, contributing to its overall performance. The control methods available include sensorless vector control and V/Hz, offering versatility for different applications.

This drive's frequency range spans from 0 Hz to 400 Hz, allowing for flexible speed control. It features overload ratings of 150% for 1 minute under constant torque and 115% for 1 minute under variable torque, which ensures reliable operation under transient conditions. The efficiency of this device is rated at 97.5%, alongside a power factor of 0.95, contributing to energy savings during operation.

In terms of protection, the drive is equipped with input trips for overvoltage (set at 570V) and undervoltage (set at 280V), safeguarding the equipment during fluctuating electrical conditions. It also has DC bus trips with overvoltage set at 810V and undervoltage set at 400V, providing comprehensive protection. The short-circuit current rating (SCCR) stands at 200 kA at 600V, underscoring the drive's robustness. For acceleration and deceleration, the 1336S-B250-AN-EN4 is programmable with two ramps, adjustable between 0 and 3600 seconds each, providing smooth transitions for motor speeds.
