FR-A820-00250-1-N6 Mitsubishi VFD

The Mitsubishi Electric FR-A820-00250-1-N6 is a general-purpose Variable Frequency Drive (VFD) from the FREQROL FR-A800 Plus Series, engineered for demanding industrial motor control applications that require precise speed regulation, advanced functionality, and dependable performance.

Rated at 5HP (3.7kW) with a 17.5-amp normal-duty output, this drive accepts three-phase input voltage from 200 to 240VAC, making it fully compatible with standard 208V and 230V industrial power systems. The wide output frequency range of 0.2 to 590Hz provides exceptional flexibility across a broad range of motor speeds and load profiles.

The 1-N6 variant includes conformal coating on the circuit board and plated conductors, providing reliable protection against moisture, dust, and corrosive environments in accordance with IEC60721-3-3 3S2/3C2. Communication is handled via Modbus RTU, enabling straightforward integration into PLC-based automation systems and SCADA networks without additional communication modules.

As part of the FR-A800 Plus Series, this drive offers more advanced capabilities than the F800 fan and pump series, including full vector control, a built-in PLC function, and safety input terminals. It supports multiple control modes including V/F control, Advanced Magnetic Flux Vector Control, Real Sensorless Vector Control, and PM motor control. The drive also features a Pulse Train Output (PTO) via the FM terminal, useful for applications requiring pulse-based speed feedback or signaling.
