The FR-A540L-220K-EC model from Mitsubishi's FREQROL FR series is engineered for high-performance applications needing precise control. With a rated current of 432 A, this drive is built to handle substantial loads effectively.

It operates within a voltage range of 3-phase 380-480 V AC and is capable of producing output frequencies varying from 0.2 to 400 Hz. This flexibility makes it suitable for various industrial applications. When overloaded, this drive can withstand a maximum capacity of 120% for up to 60 seconds, and can handle 150% for a brief duration of 0.5 seconds, demonstrating its robustness during demanding conditions under variable torque situations.

The FR-A540L-220K-EC is designed to function well in moderate humidity conditions, with acceptable levels up to 90% RH without condensation. The input and output tolerances are also noteworthy, allowing fluctuations in AC voltage from 323 to 528 V at 50/60 Hz.

Constructed with a focus on cooling, it uses forced air methods to ensure optimal performance while managing heat. The design includes an open type protective structure (IP00), suited to environments where external protection is not mandatory. With an approximate weight of 120 kg, this drive is substantial enough to provide stable operation without compromising its ability to adapt to varying conditions. Furthermore, it can be safely stored over a temperature range from -20°C to +65°C.
