FRA74137K

The Mitsubishi FRA74137K is engineered as a three-phase variable speed frequency drive (VFD) designed to efficiently handle demanding lift applications. This inverter is built for robust performance in various industrial scenarios at a rated power of 37 kW, equating to 50 HP. Operating voltage ranges between 380 to 480 VAC (including 400V, 415V, and 440V options) facilitate integration into existing systems. Users can manipulate the output frequency from a low of 0.2 Hz to a maximum of 400 Hz, giving flexibility in motor speed adjustments.

The FRA74137K features a single digital input that can be configured as either source or sink (STF), allowing for straightforward signal integration. A single analog output providing 0-10 Vdc also ensures effective monitoring or control capabilities.

Capable of delivering a rated current of 37 A, this inverter is designed with protective measures against overload, short circuits, and overvoltage, enhancing operations' reliability. The vector control methodology helps maintain precise motor control under varying speeds and loads.

Its degree of protection is IP00, indicating it is intended for installation in environments where additional protection is not required. The FRA74137K ensures optimal thermal management with forced air cooling, promoting longevity and steady operation in field conditions. Communication is achieved via the Modbus RTU protocol, ensuring compatibility across a wide range of devices and systems. Additions such as compliance with UL, cUL, and CE standards underline the unit's adherence to safety and operational specifications.
