FR-A540-0.4K

The Mitsubishi FR-A540-0.4K operates as a 400V class transistor-based inverter. This unit is versatile and optimal for powering motors with a maximum capacity of 0.4 kW. It delivers an output power of 1.1 kVA and is capable of producing an output current of 1.5 A for established performance. Designed to withstand overload conditions, this inverter extension can manage up to 150% overload for 60 seconds and even 200% for brief durations of 0.5 seconds.

Input requirements dictate use with three-phase voltage between 380 and 480 volts at a frequency of either 50 or 60 Hz. Voltage fluctuation tolerance ranges from 323 to 528 volts, while frequency variations are maintained within ±5%. At the output, the inverter generates three-phase voltage in the same range as its input.

Its adjustable frequency range spans from 0.2 Hz to 400 Hz, offering flexibility for application-specific needs. Frequency accuracy is impressive, with an analog input tolerance of ±0.2% and even ±0.01% for digital inputs, ensuring precise control. The voltage-frequency characteristics allow customization of base frequencies between 0 and 400 Hz and support both constant and variable torque operational modes.

The design of the FR-A540-0.4K incorporates natural convection cooling to maintain optimal operating conditions. It features an IP20 rated enclosure, providing adequate protection for internal components while remaining lightweight at approximately 3.5 kilograms. This inverter is well-suited for a variety of industrial processes requiring reliable and efficient motor control.
