Energy saving drives can be tailored to OEM requirements

February 19, 2013 // By Paul Buckley
The ECF three-phase inverter drives introduced by DeltaSense can be used to control permanent magnet synchronous motors widely used in energy saving fans, compressors, and pumps. The devices can also drive standard AC motors.

The high efficiency of the devices means they can 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 10 kW 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. The devices 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 ideal for controlling fans, compressors, water pumps, conveyors, mixers and other components.
