    Optidrive E3 for Single Phase Motors uses a revolutionary motor control strategy to achieve reliable intelligent starting of single phase motors.

    • Removes the need for 3 phase supply wiring
    • Provides the same features as the 3 phase Optidrive E3
    • The ideal energy saving solution where high starting torque is not required – typically including fans, blowers, centrifugal pumps, fume extractors and air flow controllers
  • Key Features

    • 110 – 115V and 200 – 240V models
    • Small mechanical envelope
    • Rugged industrial operation
    • Fast setup, and simple operation with 14 basic parameters
    • Unique motor control strategy optimised for single phase motors
    • Motor current and rpm indication
    • Built in PI control, EMC filter (C1) & brake chopper
    • Application macros for industrial, fan and pump operation
    • Bluetooth connectivity
  • Options & Software

    A range of external EMC filters, brake resistors, input chokes and output filters are available.

    Installation Options
  • Optistick Smart Compatible

    Rapid commissioning tool.

    Bluetooth NFC

Special Boost Phase

To ensure reliable starting of single phase motors, the drive initially ramps the motor voltage up to rated voltage whilst maintaining a fixed starting frequency, before reducing the frequency and voltage to the desired operating point.

Direct Mounting

Install directly on your processing equipment and be sure of protection from dust, contaminants and high‑pressure washdown.

Locally Customisable

Flat front to terminal cover with mounting points for switches and an internal PCB.

Coated Heatsink as Standard

Ideal for hygiene based operations requiring washdown — such as food and beverage

Switched Models

Simply wire up the drive, turn the inbuilt potentiometer and the motor will start running – allowing immediate energy savings.
