Product Overview: Mitsubishi FR-D720-165-NA Inverter
The Mitsubishi FR-D720-165-NA is a high-reliability, micro-drive Variable Frequency Drive (VFD) from the globally recognized FR-D700 series. Designed for 200V three-phase industrial applications, this unit features a 16.5A rated current, roughly equivalent to a 3.7kW (5HP) motor capacity. The «NA» suffix indicates the North American specification, ensuring compliance with regional electrical standards while maintaining the legendary Japanese engineering quality that Mitsubishi is known for.
High Torque and Precision Control
Despite its compact dimensions, the FR-D720-165-NA is engineered for demanding tasks. It utilizes General-purpose Magnetic Flux Vector Control, which provides a high starting torque of 150% at a low frequency of only 1Hz. This capability makes it the ideal choice for conveyor systems, high-torque pumps, and specialized machining tools. It also features integrated Safety Stop functionality (STO), which complies with international safety standards to ensure both operator and machine protection without needing complex external hardware.

Industrial Reliability and Life-Check Diagnostics
The FR-D700 series is built for a 10-year design life. The FR-D720-165-NA includes advanced diagnostic functions that monitor the health of the cooling fan and the main circuit capacitors. This allows the PLC to receive early warnings before a component reaches the end of its service life, preventing unexpected downtime. Its spring-clamp terminals ensure vibration-proof wiring, which is critical for machinery subject to constant mechanical stress.
