Offering substantial energy savings, the ECF three-phase inverter drives can be used to control permanent magnet synchronous motors widely used in energy saving fans, compressors, pumps etc. They can also drive standard AC motors. Their efficiency means they consume up to 60% less power than traditional frequency inverters used with AC motors. In addition, sensorless control allows them to drive motors without the need for rotor position sensors.
The compact drives deliver outputs from 2.2 to 10kW and can be customised to meet specific OEM designs. Fitting the 'plug and play' units simply requires the connection of power, motor and analogue control leads. They can also be controlled digitally via RS485 or Modbus inputs.
Multiple safety functions include protection against temperature, overvoltage, undervoltage, motor short circuit, locked rotor, missing start and missing motor phase. An integrated EMC filter helps meet CE compliance. The IP20 rated drives are suited for controlling fans, compressors, water pumps, conveyors, mixers and other components.
