Product Details:

Allen-Bradley 1331-AAF10 belongs to Rockwell Automation Bulletin 1331 series single-phase micro adjustable frequency AC drive. Rated 0.5HP / 0.37kW, 120V single-phase AC input, output current 2.4A, output frequency range 0~400Hz. This is a discontinued compact VFD designed for single-phase AC power supply occasions to drive small three-phase AC motor variable speed control in industrial automation systems. The base unit is equipped with simple control terminal, users can install optional local control panel separately for local parameter setup and manual operation.

This inverter adopts NEMA Type 1 (IP30) enclosure and supports panel mounting inside control cabinets. It uses V/Hz open loop control strategy, supports continuous speed regulation for small fans, pumps and light-duty conveyor equipment. It integrates comprehensive built-in protection functions including overcurrent, overvoltage, undervoltage, overheat and motor electronic overload protection to prevent equipment damage under abnormal working conditions. It accepts 0-10V or 4-20mA analog signals for remote speed control and supports accessory expansion interface. It complies with UL industrial standards and is widely used for spare part replacement and maintenance of legacy production lines.

Each Allen-Bradley 1331-AAF10 undergoes strict factory testing before shipment, including power-on running test, insulation resistance test and protection function verification to ensure stable performance in industrial automation environments.
