core function
1336F-BRF20-AE-EN-L5E is a 20HP (15kW) three-phase AC inverter from Allen-Bradley, and is a classic product of the 1336 PLUS series. The inverter adopts voltage vector control technology, supports 380-480V AC input, and integrates EMC filters. It is designed for industrial motor speed control and is widely used in load scenarios such as fans, pumps, and conveyors.
High-performance motor control
It has an open-loop vector control mode, which can achieve stable operation at a low frequency of 0.5Hz, a starting torque of 150% of the rated torque, and supports custom V/f curves. The built-in PID regulator can directly receive process feedback signals (such as pressure/flow transmitters) to achieve closed-loop control, and is typically used in constant pressure water supply systems.
Intelligent protection and diagnosis
Integrated multiple protection functions: adjustable overcurrent/overvoltage/undervoltage protection thresholds, real-time monitoring of IGBT temperature, and quick location of problems through fault codes (such as F11 overload). Supports Modbus RTU communication protocol, and can read current, frequency and other operating parameters through the host computer, which is convenient for preventive maintenance.
Industrial environment adaptability
Adopts coated circuit board design, adapts to 0-50℃ ambient temperature (de-rated above 40℃), protection level IP20 (needs to be installed in the cabinet). Built-in DC bus brake unit, can stop quickly, especially suitable for material conveying systems with frequent start and stop. Compatible with a variety of brake resistors (such as 1336-RB series) to meet the needs of heavy-duty inertial loads.
