1336S-B025-AA-FR-HA2

The AC drive model 1336S-B025-AA-FR-HA2 from the Allen Bradley 1336 PLUS Drives series is engineered for optimal control in motor applications. This drive operates effectively with 3-phase input voltage of 380 to 480 VAC, accommodating a variance of ±10%. An input frequency range of 48 to 62 Hz allows for flexibility in application setups. It delivers a constant torque motor power output of 18.5 kW, which is equivalent to 25 HP.

In terms of output performance, the drive manages current ratings of 39 A for constant torque and 42 A for variable torque, supporting an output kVA of 31 for constant torque and 33 for variable torque setups. With overload protections measured at 150% for one minute in constant torque conditions and 115% for variable torque, it ensures safe operation.

The enclosure, rated at IP20 (NEMA Type 1), makes this drive suitable for environments free of excessive dirt and moisture. It utilizes a sine-coded PWM control strategy along with an adjustable carrier for efficient operation. Motor control can be adjusted between sensorless vector mode and V/Hz mode to best suit application needs. The drive boasts an output frequency range of up to 400 Hz, fine-tuning performance as required.

Accuracy is a key feature, with frequency precision at ±0.01% of the digital setpoint or ±0.4% of the maximum analog range, offering reliability in control. Additionally, current regulation limits proactive measures at 20-160% of the rated current to prevent overload situations. At a rated load and nominal voltage, the drive achieves impressive energy efficiency of 97.5%, making it a solid choice for energy-conscious operations.
