FRA540L800KNA

Mitsubishi's FRA540L800KNA belongs to the FREQROL FR-A5 series, recognized for its efficiency in controlling motor drives. This variable frequency drive operates at input voltages ranging from 380 to 480V AC, catering to both 50Hz and 60Hz environments effectively. Capable of handling a motor capacity of 800 kW while ensuring constant torque, this drive offers excellent reliability for heavy-duty industrial applications.

The voltage fluctuations that the unit tolerates are between 323V to 528V, ensuring stability under varying load conditions. Frequency fluctuations are controlled within ±5%, contributing to consistent performance. The output frequency can be adjusted between 0.2Hz and 400Hz, allowing for versatile operation tailored to specific process requirements. The precision of the frequency is maintained at ±0.2% with analog input signals.

The FRA540L800KNA is designed to deliver starting torque of up to 150% at 0.5Hz, providing strong initial push for loads. Furthermore, it can sustain overload capacities of 150% for 60 seconds and even 200% for short bursts of 0.5 seconds, which is critical for applications requiring brief surges of power. This drive offers flexible acceleration and deceleration times, adjustable from 0 to 3600 seconds using linear or S-curve profiles to meet needs for gradual speed changes.

Cooling is managed through a forced air system, which is essential for maintaining optimal temperatures during operation. The unit is constructed for open environments (rated IP00/IP20), suitable for internal installations in controlled spaces. The operating temperature is supported in a range of -10°C to 50°C, ensuring adaptability to various industrial conditions. The overall construction of the FRA540L800KNA aligns with heavy-duty applications, reinforcing Mitsubishi's commitment to performance and reliability.
