AC Inverter is a high-performance vector control AC Drive Inverter. The frequency reference can come from built-in potentiometer, analog input reference and serial communication. The capacity can go up to 30kW. The great feature is the configurable voltage/frequency characteristics to achieve the power-saving control.


High Starting Torque

  • AC Inverter features the most advanced control technique of high-speed vector current control-200% output torque at 1Hz. In either starting area (motor acceleration) or braking area (motor deceleration), it keeps the stable and smooth operation to satisfy the requirement of application that needs large starting torque.
  • Torque auto compensation can be achieved by auto-tunning after one parameter setting for EI-650 to reach the best efficiency.

Built-In EMI Noise Filter

  • The built-in EMI noise filter (optional for under 2HP) can greatly decrease the RFI noise or current interruption produced from inverter.
  • EI-650 also meets European EMC compliance.

Multiple Functions

  • Configurable voltage / frequency characteristics: V/F constant torque control, variable torque control, automatic torque boost control, sensorless vector control, automatic energy savings , dynamic automatic energy-saving control and permanent-magnet motor control.
  • Start/stop: Three-wire control, multifunctional input terminal, digital operator and RS485 communication control.
  • Frequency reference: Built-in potentiometer, 4-20mA, 0-10V /\ , \/ key and serial communication.
  • The sum of 2 analog signals (VIA/VIB) can be used as a frequency command value.
  • 16 multi-speed setting, jog command, NPN, PNP input signal switch.
  • PID feedback control with built-in 24VDC power supply for process transducer.
  • All EI-650 units are equipped with built-in IGBT braking transistors.
