AC Motor Drives
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.

- High starting torque (150%/ 3Hz) to start the machine smoothly.
- 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
- 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)
- 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).
