Single Phase Input / Output
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
Optistick Smart Compatible
Rapid commissioning tool.
Options & Software
A range of external EMC filters, brake resistors, input chokes and output filters are available.
Installation Options
- on board as standard
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.



Enclosure Options
Optidrive E3 Single Phase is available in a range of IP20 & IP66/NEMA 4X enclosures.
