For a 1×230 V supply, the motor winding must support 230 V connection. A 3×400 V supply calls for a 400 V class drive.
Delta variable frequency drives – selection and prices.
Choose a drive by range, power, voltage, phases, communication, EMI filter, STO or IP rating. Each product has a photograph, price and technical detail page.
Delta drives by series

Choose a suitable model.
Prices: Each drive shows the price including and excluding VAT. Availability and shipping are confirmed in the quotation.
What to check before ordering.
Power in kW alone is insufficient. Check the motor nameplate and the application.
The drive’s output current and overload capacity must cover the motor, starting conditions and load.
Pumps and fans have different requirements from conveyors, extruders, winders or lifting mechanisms.
Check the braking resistor, EMC filter, STO and communication with a PLC or higher-level system for the application.

Variable frequency drives in practice.
Which drive suits a 1.5 kW motor?
Compare rated motor current, supply voltage, winding connection, starting load and overload requirements.
Can a single-phase 230 V supply run a three-phase motor?
Yes, if the drive provides 3×230 V output and the motor winding supports 230 V operation, commonly in delta connection. Check the motor nameplate.
Does a drive save electricity?
The largest savings can occur in pumps and fans when lower speed replaces mechanical throttling. Savings are not automatic with a constant load.
What is the difference between a VFD and a soft starter?
A soft starter primarily controls starting and stopping. A VFD also regulates speed continuously and can control torque, processes and communication.
