1336F-BRF10-AN-EN-LG

The model 1336F-BRF10-AN-EN-LG from Allen Bradley is an adjustable frequency AC drive recognized for its operational efficiency and advanced features. This drive is capable of a maximum motor power of 0.75 kW, equating to approximately 1 horsepower. It works effectively within a variable input voltage range of 380 to 480 volts AC, as well as 513 to 620 volts DC. The impressive efficiency rating of 97.5% when under rated load highlights its capability to minimize energy consumption during operation.

Furthermore, the drive is equipped with robust transient protection rated at 6000 volts for the line connections and 1500 volts for the logic control side, ensuring enhanced reliability and safety. The drive operates with an output current of 2.1 A at 480 volts under constant torque applications and has a higher output of 2.3 A for variable torque applications. An adjustable output frequency capability from 0 to 400 Hz offers flexibility in application. The frequency accuracy is notable with digital precision at ±0.01% and analog at ±0.4%, assuring accurate speed control.

Acceleration and deceleration ramps are programmable, providing two distinct ramp profiles with adjustable durations from zero to 3600 seconds in 0.1-second increments, facilitating smooth starting and stopping of equipment. Overload capabilities allow a continuous current limit of 150% for 60 seconds in constant torque scenarios and 115% in variable torque, enabling the motor to handle transient loads effectively.

The drive also features a current limit setting from 20% to 160%, with independent proportional-integral (PI) gains, allowing tailor-made control adjustments. Additionally, with a power ride-through time of 15 milliseconds at full load, the 1336F-BRF10-AN-EN-LG ensures minimal disruption during power fluctuations, contributing to overall system stability.
