FR-A540-0.4K-EC

The Mitsubishi FR-A540-0.4K-EC inverter is engineered for reliable operation in applications requiring precise control of electric motors. Operating with a 400V input, this transistor inverter allows for an output frequency ranging from 0.2 Hz to 400 Hz, making it suitable for varying process requirements. It boasts high-frequency accuracy, ensuring consistent performance with an analog measurement tolerance of ±0.2% and ±0.01% for digital reads.

Users can select from constant or variable torque control settings based on application needs, enhancing operational flexibility. This inverter can configure up to 15 discrete speed settings throughout its frequency range, facilitating adaptable motor performance.

For applications requiring rapid adjustments, the FR-A540-0.4K-EC includes a DC dynamic brake whose parameters—frequency, time, and voltage—can be adjusted for optimal performance. With an overload capacity rated at 150% for up to 60 seconds and 200% for half a second, this inverter can easily manage sudden spikes in load.

Featuring a compact design and an IP20 protective structure, the unit is designed for use in standard environments without excessive exposure to dust or moisture. It operates efficiently in ambient temperatures ranging from -10°C to +50°C under constant torque conditions.

A rated current of 1.5 A provides the necessary power for motor start-up, featuring an impressive starting torque of 150% at a low frequency of 0.5 Hz. Torque boost settings provide manual adjustment capabilities for specific operational demands. Additionally, both acceleration and deceleration times are configurable from 0 to a maximum of 3600 seconds, allowing for customized control during start-up and stop sequences.
