Single Phase to 3 Phase VFD – 220V In, True Three-Phase 380V/400V Out
A single phase to 3 phase VFD takes single-phase 220V input and delivers true three-phase output, so you can drive standard three-phase machines without installing a new supply line or a separate transformer. The SHZK 300-S3 is a single phase input three phase output variable frequency drive that converts 220V to 380V, 400V or 415V – a drop-in frequency converter single phase to three phase for motors, pumps, fans and compressors up to 18.5kW.
We factory-test every S3 unit against a real three-phase motor like the one below (100% full-load), so the 220V-to-380V conversion is proven before it leaves our plant – not just on paper.
In our factory test setup: a single-phase 220V S3 VFD driving a standard three-phase 380V motor – the exact configuration we ship to workshops across Southeast Asia.
What Can a 220V to 3 Phase Converter Drive?
- Run a 3 phase motor on single phase supply – no rewinding, no phase converter add-on
- Borehole, deep well, irrigation and booster pumps
- Fans, blowers, air compressors and small production machines
- CNC spindles and other 380V three-phase equipment
