Description
Core Product Summary
The Mitsubishi FR-SE-2-11K-A-C is an industrial variable frequency drive (VFD) from Mitsubishi Electric’s FR-SE frequency inverter series. Rated for 11 kW motor output power, this AC drive controls three-phase induction motor speed and torque across continuous process and automated manufacturing applications.
Operating on a 200 V class three-phase AC power input, the unit converts fixed-frequency line power into variable-voltage, variable-frequency output to optimize energy usage and operational control. Built for panel-mount installation within industrial control cabinets, the FR-SE-2-11K-A-C includes built-in protection logic, terminal block I/O connections for remote control, and localized diagnostic LED indication.

Detailed Product Overview
The Mitsubishi FR-SE-2-11K-A-C frequency inverter performs speed regulation, smooth acceleration, and controlled deceleration for standard three-phase AC induction motors rated up to 11 kW. By replacing fixed-speed motor starters with controlled frequency modulation, the drive reduces mechanical strain, lowers line inrush currents, and improves process efficiency in fan, pump, conveyor, and general automation applications.
The internal power circuit conditions incoming 200 V three-phase line power through a diode bridge rectifier and DC bus capacitor bank before synthesizing a variable 3-phase output via IGBT power transistors. Integrated protective features continuously monitor operating conditions to detect overcurrent, overvoltage, undervoltage, overload, and heatsink thermal overload events.
During installation and system integration, system engineers connect line power, motor leads, and control signals via the main terminal strip. Proper electrical grounding, line fuses or circuit breakers, and adequate thermal clearance around the chassis heatsink fins are mandatory to maintain rated drive output and operating life.

Dimensions, Mounting & Connection Notes
- Mounting Orientation: Must be installed vertically on a flat panel or cabinet backplate to facilitate heat dissipation.
- Cooling Clearance: Maintain specified top and bottom clearances around internal heatsink channels for unrestricted air circulation.
- Wiring Requirements: Use rated multi-strand copper conductors for power terminals (R/L1, S/L2, T/L3, U, V, W) and shielded cable for low-voltage analog and digital control lines.
- Grounding: Connect a dedicated protective earth (PE) ground wire directly to the drive ground terminal to minimize electromagnetic interference (EMI).
