FR-E740-0.4K

Mitsubishi presents the FR-E740-0.4K, a variable frequency drive featuring several functional attributes tailored for robust performance. It boasts a rated power capacity of 1.2 kilovolt-amperes and operates at a rated output of 0.4 kilowatt, correlating to half a horsepower. The device draws a current of 1.6 Amperes and supports a power supply voltage ranging from 380 to 480 Volts AC. Composed of compact dimensions, the unit measures 5.5 inches in height, 5 inches in width, and 6 inches in depth (140 x 127 x 152 mm). Moderately lightweight, it weighs approximately 3.31 pounds (1.5 kilograms).

Designed specifically for 3-phase systems, the FR-E740-0.4K utilizes a cooling method based on heatsinks to maintain optimal operating temperatures. The available output frequency spans from 0.2 to 400 Hertz, making this drive suitable for various application requirements. Control methodologies integrated within the drive include voltage/frequency control and sensorless vector control, allowing for precise motor operation. The unit’s overload capability permits a maximum of 150% for one minute, providing additional performance advantages during momentary high load conditions.

Communication with external devices is facilitated via multiple serial ports, specifically, RS-232, RS-422, or RS-485 connections, promoting connectivity flexibility. Additionally, the integrated Modbus RTU protocol enhances remote operational monitoring and controls. The drive is encased within an IP20-rated housing, affording it basic protection from particulate intrusion and contact, extending its operational reliability under appropriate conditions.
