The Mitsubishi FRA560L900K12R is a large-capacity inverter with impressive capabilities. Specifically designed for constant torque applications, it has a compatible motor capacity of 900 kW. The inverter's rated output is 1200 HP, supported by a rated current of 1210A.
In terms of voltage characteristics, this inverter operates with a 3-phase output of 575V and can handle an input voltage range of 488 to 632V, functioning effectively at 50 or 60 Hz. Frequency control is precise, with accuracy figures of ±0.2% in analog mode and ±0.01% in digital operation. It supports voltage/frequency characteristics adjustable between 0 and 400 Hz, allowing for constant or variable torque settings.
The inverter incorporates a DC dynamic brake capable of operation from 0-120 Hz, allowing up to 30% voltage adjustment in a deceleration time of up to 10 seconds. This flexibility enables rapid response to changes in operational demands.
Moreover, the FRA560L900K12R can produce a starting torque of 150% at a frequency of 0.5 Hz, making it suitable for high inertia loads. Notably, it offers impressive overload handling capabilities, including a 150% load capacity for 60 seconds and even up to 200% for brief periods of 0.5 seconds.
User-defined acceleration and deceleration settings can be adjusted from 0 to 3600 seconds, featuring options for both linear and S-curve ramps, facilitating smooth transitions during operations. Cooling is managed through a forced air method, ensuring reliable performance within its specified operational temperatures ranging from -10°C to 50°C for constant torque (CT) applications and -10°C to 40°C for variable torque (VT).
The protective structure of the inverter complies with an open type rating (IP00/IP20), ensuring suitability for various installations while maintaining accessible conditions for maintenance.
