Overview
The Allen-Bradley 1336F-BRF50-AA-EN is a 5 HP (3.7 kW) variable-frequency AC drive from the 1336 PLUS II product family. This Series B open-frame drive is designed for three-phase AC motors operating on 380–480V AC or 513–620V DC input power. With sensorless vector control and PWM output topology, it delivers precise speed and torque control for general-purpose industrial motor applications while maintaining compact dimensions and cost-effective performance.
