FR-A740-315K

The FR-A740-315K, part of Mitsubishi's FREQROL FR-A7 series, is an advanced three-phase inverter specifically designed for demanding applications. This unit showcases a motor capacity of 315 kW and a substantial power supply capability of 465 kVA, making it suitable for high-performance environments.

The inverter operates with a rated current of 610 Amps, ensuring that it can manage significant power loads consistently. It provides continuous regenerative torque rated at 10%, delivering enhanced control for various industrial applications. This model does not include a brake transistor, indicating its focus on straightforward operational functionality.

In terms of thermal management, the FR-A740-315K employs a forced air cooling system to maintain optimal performance levels. Note that it operates as an open-type enclosure, making it crucial to install in environments that suit such a configuration. The device conforms to U.S. specifications, ensuring compatibility with standards and effectiveness.

When it comes to overload performance, the inverter can handle current ratings of up to 150% for a duration of 60 seconds and peaks at 200% for a maximum of 3 seconds when surrounding temperatures reach 50 degrees Celsius. This capability allows for brief surges in operational demands without compromising performance.

For power requirements, it operates effectively within a voltage range of 380 to 480 Volts AC. The device weighs around 260 kg and does not include a fan, streamlining its design for specific installation contexts where airflow can be managed differently.
