The state-of-the-art, high efficiency drives use up to 80% less power than traditional frequency inverters used with AC motors, claims the manufacturer. In addition, sensorless control enables them to drive motors without the need for rotor position sensors.

Available with power outputs ranging from 180 W to 1500 W, the single phase drives can operate at efficiencies of over 96%. Since they are passively cooled they can be supplied in high IP rating enclosures, making them suitable for harsh environments. The drives can be customised to suit OEM applications. Fitting is simple as all that is necessary is to connect the 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.
