FRA540L220KR1

The Mitsubishi FRA540L220KR1 stands out as a variable frequency motor drive tailored for dynamic control of motor operations. This unit weighs approximately 220 kg (485 lbs.) and is engineered to function in environments ranging from -10°C to +50°C with a relative humidity of less than 90%. Designed with an open-type (IP00) enclosure, the FRA540L220KR1 utilizes a forced air cooling system to maintain optimal operating temperatures during use.

This drive encompasses multiple control systems, including V/F and flux vector control, allowing it to cater to diverse operational needs. Users can set acceleration and deceleration rates between 0 and 3600 seconds, with options for linear or S-pattern ramps. Motor compatibility extends to units rated at 220 kW or up to 280 kW, providing flexibility for various applications.

In terms of power ratings, this model supports a constant rated power of 350 HP and a variable rated power of 450 HP, ensuring versatility depending on operational requirements. The overload capability allows for 150% of rated current for up to 60 seconds and an increase to 200% for brief intervals of 0.5 seconds, which can be beneficial for handling starting loads or transient conditions.

This drive's input voltage tolerance ranges from 323 to 528V AC, and it functions at an input frequency of either 50 or 60 Hz within a ±5% variance. Its rated output voltage falls within 380 to 480V AC, 3-phase configuration. The supply capacities are rated at 329 kVA for constant applications and 417 kVA for variable use. The FRA540L220KR1 is engineered for high-performance applications that necessitate precision control and adaptability.
