The Mitsubishi FRA540L530KNA large-capacity inverter is characterized by its ability to handle substantial loads with precision and reliability. Designed for environments requiring high-performance motor control, this inverter supports a frequency accuracy of ±0.2% for analog outputs and a refined ±0.01% for digital signals. Its capability to operate over a broad frequency range from 0 to 400 Hz allows for effective management of constant or variable torque needs.
With a starting torque of up to 150% at 0.5 Hz, the unit is well-suited for applications demanding robust initial power. Users can manually adjust the torque boost to customize performance further. The inverter also features adjustable acceleration and deceleration times between 0 and 3600 seconds, enabling linear and S-pattern control for smoother operation.
It is equipped with a DC dynamic brake operational up to 120 Hz for braking requirements. This brake can be set for bursts of 0 to 10 seconds at 0 to 30% of voltage, providing additional control during operations. It supports an applicable motor capacity of 530 kW for constant torque (CT) and 600 kW for variable torque (VT), with rated capacities of 800 HP (CT) and 900 HP (VT).
This inverter's rated currents are 1010 A for CT and 1152 A for VT, ensuring efficient performance across various motor sizes. Cooling is managed through a forced air system, and it can function within an ambient temperature range of -10°C to 40°C for VT applications and from -10°C to a maximum of 50°C for CT applications.
The FRA540L530KNA is designed with an open-type protective structure, classified as IP00/IP20, which may require additional prevention measures in harsh environments to ensure longevity.
