The Mitsubishi FR-A740-00380-EC is a reliable variable-speed drive specifically designed for industrial applications. Operating within a voltage range of 380 to 480 VAC, this unit has a tolerance range between -15% and +10%. It is configured for 3-phase power applications, which enhances its compatibility with many motor systems. Rated at 15 kW for output power, it can efficiently manage currents of 31 A during operation.

This drive operates at either 50 or 60 Hz frequencies, making it suitable for varying industrial frequency requirements. The control mechanism is PWM (Pulse Width Modulation), which allows for precise speed management and energy efficiency. Cooling is achieved through a forced air system, which maintains optimal operating temperatures and prevents overheating.

The FR-A740-00380-EC is designed with overload capacity adhering to industrial standards, supporting up to 150% of its rated current for short bursts of 60 seconds—this characteristic benefits applications requiring additional power on startup or during sudden load increases. With compact dimensions of 220 mm in width, 300 mm in height, and 190 mm in depth, along with a weight of 7.5 kg, it can fit into various installation settings without demanding excessive space.
