FRA540L160KR1

The Mitsubishi FRA540L160KR1 unit belongs to the FREQROL FR-A5 series and is known for its advanced variable frequency drive (VFD) capabilities. This model is designed to handle a motor capacity of 160 kW in constant torque applications or 220 kW for variable torque scenarios. The VFD is rated to support up to 250 HP in constant torque settings and 350 HP for variable torque use.

Providing a continuous rated current output of 325 A for constant torque and 432 A for variable torque further enhances its performance in demanding environments. The unit can power equipment with a facility capacity of 248 kVA for CT and 329 kVA for VT applications. Forced air cooling ensures reliable operation, while the device’s open-type enclosure indicates IP00 protection.

The FRA540L160KR1 incorporates a control system that can utilize Soft-PWM, voltage/frequency (V/F), or vector control methods, providing flexibility for diverse applications. The output frequency can be adjusted between 0.2 and 400 Hz, making it suitable for various speed control requirements. The module allows for an acceleration and deceleration time of up to 3600 seconds, which can be set to either linear or S-curve profiles for smoother operations.

Designed to function in ambient conditions, it operates effectively within temperatures of −10°C to +50°C and tolerates relative humidity levels of up to 90% without condensation. The unit possesses overload capabilities, handling 150% for 60 seconds and 200% for half a second in CT scenarios, while it supports 120% for 60 seconds and 150% for half a second in VT applications.

Output voltage is provided in a 3-phase configuration, ranging from 380 to 480V at 50 or 60 Hz. The input voltage specifications align with the need for flexibility, accommodating 323 to 528V AC, and operate within input frequency ranges of 50/60 Hz, ±5%.
