The FR-F740 frequency inverter drives from Mitsubishi Electric are designed for the special needs of pumps and fans. These inverters can significantly enhance the energy balance of pump and fan applications - particularly in the low-speed range and in low-load operation, where energy savings of up to 60% can be achieved. Additional savings are made possible by Mitsubishi Electrics innovative OEC (Optimum Excitation Control) technology. This system ensures that the optimum magnetic flux is always applied to the motor, thus reducing losses. The result is maximum utilisation of motor capacity at maximum efficiency.
