The 1336F-B050-AA-EN-L6 model is an adjustable frequency AC drive from Allen Bradley's 1336 PLUS II series, engineered for efficient motor control in industrial applications. It supports input supplies ranging from 380 to 480 volts AC and offers an output power capacity of 37 kW, equivalent to 50 horsepower.
This unit features constant torque ratings of 48-60 kVA and 73 A input with a 75 A output. In addition, it accommodates variable torque ratings of 62 kVA, with 75 A input and 77 A output. The operational frequency ranges from 0 to 400 Hz, making it versatile for diverse control needs.
The drive boasts precise frequency accuracy: ±0.01% for digital settings and ±0.4% for analog configurations. A sensorless vector control method enhances the performance of connected motors, while the selectable V/Hz control mode provides flexibility in controlling operational profiles.
Acceleration and deceleration are managed through dual programmable ramps, allowing for tailored performance based on application requirements. In the case of power interruptions, the drive demonstrates ride-through capability, maintaining logic hold for up to 2 seconds following a 15 ms power loss.
Furthermore, the 1336F-B050-AA-EN-L6 includes an overload capacity of 150% for constant torque and 115% for variable torque over a one-minute span, ensuring the ability to handle transient overload conditions effectively. This drive is packaged in an IP20 (NEMA 1) enclosure, indicating it is suitable for use in environments where exposure to dust and other particulates is minimal, while the control interface operates at 115 V AC logic, facilitating seamless integration into existing systems.
