The 1336F-B250-AE-IT from the Allen Bradley 1336 PLUS II Drives series is an adjustable frequency AC drive capable of delivering precise motor control for various industrial applications. This drive achieves an efficiency rating of 97.50% at its rated load. It utilizes a Sine-Coded Pulse Width Modulation (PWM) control method with the flexibility of a programmable carrier frequency ranging from 2 to 8 kHz.

Spanning an output frequency range from 0 to 400 Hz and possessing ±0.01% digital accuracy, this unit provides reliable operation. The communication interface adopted is based on the DeviceNet protocol, ensuring compatibility with Adapter 6. This model is adaptable to different motor control modes, including sensorless vector control or customizable voltage/frequency (V/Hz) operation.

The drive supports a rated input voltage range of 380 VAC to 480 VAC, operating optimally within a tolerance of ±10%. It has a constant torque power rating of 250 HP (187 kW) and a variable torque power rating of 187 HP (140 kW). For heavy-duty applications, it accommodates a full load output current of 325 A.

In terms of environmental specifications, the 1336F-B250-AE-IT features an enclosure rated at IP20/NEMA Type 1, suitable for general-purpose use. Under a full load condition, the input current is measured at 259 A. The trip thresholds for overvoltage and undervoltage are set at 570 V AC and 280 V AC, respectively. Additionally, the device functions in ambient temperatures between 0°C and 40°C (32°F to 104°F), making it appropriate for many industrial environments.
