FRA540L280KTA

The Mitsubishi FRA540L280KTA is a sophisticated AC inverter drive suitable for demanding industrial tasks. It boasts a frequency accuracy of ±0.2% based on the maximum output frequency using analog input. This AC drive allows users to adjust the base frequency, which can range from 0 to 400 Hz, enabling flexibility in applications requiring either constant or variable torque characteristics.

Operating efficiently within a rated input voltage range of 380 to 480 volts AC at 50 or 60 Hz, this 3-phase drive can handle input fluctuations between 323 and 528 volts AC. The FRA540L280KTA is engineered to provide a substantial starting torque of 150% at just 0.5 Hz utilizing advanced flux vector control, making it ideal for applications needing robust start capabilities. Manual adjustment for torque boost further enhances its operational flexibility.

The unit offers an output frequency between 0.2 and 400 Hz, accommodating a variety of operational demands. Acceleration and deceleration times can be programmed from 0 to 3600 seconds with options for linear or S-curve settings, allowing for smooth transitions in speed. Power capacity is impressive, as this inverter can manage overloads of 150% for 60 seconds and up to 200% for brief intervals of 0.5 seconds while maintaining constant torque.

Included features such as a DC dynamic brake allow frequency adjustments up to 120 Hz with variable voltage settings, providing additional control over the motor. Cooling is achieved via forced air, ensuring the unit operates optimally under heavy loads. The drive is constructed in an open type with an IP00 protective rating, thus recommended for environments with minimal exposure to dust or moisture.

With an analog input resolution of 12 bits to accommodate ±10V or 0-10V signals, it ensures precise feedback control. Weighing approximately 235 kg (518 lbs.), this unit is designed for reliability and durability in rigorous industrial applications.
