FR-S540E-0.75K-EC

Mitsubishi's FR-S540E-0.75K-EC is a robust frequency converter designed for various industrial applications. It is compatible with motors rated at 0.75 kW and can produce up to 1.6 kVA of power. Its rated output current is 2.1 A, which supports effective motor performance.

Thanks to its inverse-time handling, the device can manage overload conditions quite efficiently, with a capacity of 150% for 60 seconds and a peak of 200% for half a second. The output voltage is maintained within a three-phase range of 380V to 480V, whereas the input voltage aligns with the same specifications, functioning at 50Hz or 60Hz. It also tolerates voltage variations from 325V to 528V, ensuring stable operations under fluctuating supply conditions. Frequency variations are permitted within a tolerance of ±5%.

Natural air cooling is incorporated for thermal management, which helps maintain operational integrity during use. Control modes can be selected as per requirement, allowing flexibility between soft-PWM/high-frequency PWM and V/F control with automatic torque boost features.

The converter provides a frequency output range stretching from 0.5Hz to 120Hz, with the ability to set the starting frequency between 0Hz and 60Hz. Additionally, it exhibits a significant starting torque capability of 150% at 5Hz, which is bolstered by automatic torque enhancement. Users can also adjust acceleration and deceleration settings ranging from 0.1 seconds to 999 seconds, allowing for both linear and S-pattern adjustments, fitting various application needs.
