The FR-A740-00170-EC from Mitsubishi modularly illustrates a variable speed drive optimized for diverse automation processes. This device operates efficiently on a 3-phase voltage supply between 380 and 480 VAC, adhering to the specified tolerances of -15% to +10%. Its rated power is quantified at 5.5 kW, making it robust for numerous applications.

Operating with a nominal current of 12 Amps, the drive is compact, measuring 220 mm in width, 260 mm in height, and 170 mm in depth, while weighing 7.1 kg for manageable installation. It supports both 50 Hz and 60 Hz frequency operations, accommodating various standards within industrial environments.

The control mechanism relies on PWM (Pulse Width Modulation) for enhanced performance and efficiency during motor speed adjustment. In instances of high demand, the unit exhibits an overload capacity, capable of handling up to 150% of its rated load for 60 seconds. The drive employs forced air cooling to promote optimal operation, maintaining necessary temperature levels under load.
