Item No. : EI-450M Series


EI-450M Series



220V Class (1-Phase Input) 200W~1.5kW
220V Class (3-Phase Input) 200W~1.5kW
440V Class (3-Phase Input) 400W~1.5kW

AC Drive is a mini power saving inverter. It features the most simple AC induction motor controller from 200W up to 1.5kW for 220VAC and 440VAC Class. The status indicator LED and 7-segment display are built in and can show the data value for the easy reading.
AC Drive is small, quiet and powerful.

Full-range-Automatic Torque Boost
  • High starting torque (150%/ 3Hz) to start the machine smoothly.
Complete Protective Functions
  • High-speed current limit to prevent over current (200% or more of the rated current), tripless operation (Momentary power loss restart, stall prevention, fault reset)
  • Built-in rush current limited circuit
  • Ground fault protection
Functions
  • Multi-speed setting (up to 9 steps):2-step acceleration/ deceleration, 2-step jump frequency, UP/DOWN selection, jog command…etc.
  • Full-range automatic torque boost, slip compensation, stall prevention, over torque detection, DC injection braking…etc.
  • Remote speed reference:0~10VDC, 4~20MA/0~20MA, multifunction input and output terminal, analog output monitor, NPN and PNP input signal switch
  • MODBUS message format, RS485 series communication card available (Optional accessory)
  • Built-in digital keypad operator (RCUS-450) with complex digital keypad operator (RCU-450) (Optional accessory)
Broad Application
  • Substitute Magnetic Contact
    • No contact ensures, no transmission and maintenance requested.
  • Conveyer
    • Soft start/stop function enables goods to stand still on conveyer.
  • Single Phase Power Input
    • Using single-phase power drives three-phase motor to rise the efficiency.
  • Flow Machine(Fan-Pump)
    • Changing motor speed smoothly makes the best of flow to save energy.
  • Food Processing Machine
    • The operation speed can be changed by using multi-speed functions (up to 9-step speed) and pre-set speed.
  • Standard Mechanization
    • The machine controlled by the inverter/drive can be used with local power frequency (50/60 Hz).
