VFD Series
Variable Frequency Drives
Speed control that cuts energy on every part-load drive.
AC drives for speed and torque control of the motor range. On pumps, fans and conveyors that spend most of their life below full load, matching motor speed to demand is the single largest energy saving available on the drive train.
- Power range
- 0.4 kW to 55 kW
- Input supply
- 1 phase and 3 phase
- Control
- V/f and vector
- Output frequency
- 0 Hz to 400 Hz
Built for Duty
What separates the VFD Series from a general-purpose drive.
Sensorless vector control
Holds torque at low speed without an encoder, for extruders, mixers and loaded conveyor starts.
Built-in PID
Closes the loop on pressure, flow or level on the drive itself, with no external controller.
Modbus RTU
RS485 as standard so drives report into an existing PLC or SCADA without a gateway.
Soft start and stop
Ramped starting removes the mechanical shock and inrush current of direct-on-line starting.
Protection suite
Over-current, over-voltage, phase loss, stall prevention and thermal protection on every unit.
Commissioned on site
Parameter sets configured against the driven load rather than shipped at factory defaults.

Technical Specifications
Variable frequency drives — rating against supply and current
| Rating | Input supply | Rated output current | Control mode | Enclosure |
|---|---|---|---|---|
| 0.4 kW to 2.2 kW | 1 phase 230 V | 2.5 A to 10 A | V/f, vector | IP20 |
| 0.75 kW to 5.5 kW | 3 phase 415 V | 2.5 A to 13 A | V/f, vector | IP20 |
| 7.5 kW to 15 kW | 3 phase 415 V | 17 A to 32 A | V/f, vector | IP20 |
| 18.5 kW to 30 kW | 3 phase 415 V | 38 A to 60 A | V/f, vector | IP20 |
| 37 kW to 55 kW | 3 phase 415 V | 75 A to 110 A | V/f, vector | IP20 |
