Product Description

ATO 220V 230V 240V single phase to 3 phase VFD VSD, 220V 230V single phase to three phase VFD variable frequency drive, convert single phase to 3 phase for AC motor speed controls, RS485 enabled. vfd 220v input 220v 3 phase output widely used in spindle motor, drill press, CNC, compressor, milling, HVAC, lathe, pumps, conveyors, cooling, fan, and three phase motor. etc.
- Note:
The rated current of the ATO single to 3 phase VFD refers to the three-phase output current.
The input current of the ATO single to three phase VFD is approximately 1.5 times the output current.
- How to choose a right VFD?
Except for the input voltage, there are two additional conditions that need to be met:
1. The rated current of the VFD should be greater than the rated current of your motor, preferably by at least 30%.
2. The rated power of the VFD should be greater than the rated power of your motor, preferably by at least one levels.
If you're unsure which VFD is suitable for your motor, please provide us with a photo of your motor nameplate, tell us the input power supply, and your requirements. We'll then recommend the appropriate VFD model for you.
- Tips on ATO VFD with SN numbers starting with 9000:
Input frequency: 47-63Hz (so 50/60Hz is supported);
Output frequency: 0-1000Hz (Default: 50Hz, if you need the output frequency to be 60Hz, please set: P0.02=60, P0.05=60, P0.06=60, P8.04=60)
- How to set the output frequency to 1000Hz?
set: P0.05=1000. P0.06=1000 P8.04=1000, P0.21=1

What Real-life Problems can be Solved by using ATO Single Phase to 3 Phase VFD?
- 220v-240v Single to three phase VFD can solve the problem of power phase mismatch, that is, the power supply is single-phase, and the equipment uses three-phase power.
- 220V output VFD can solve the problem of power frequency mismatch, that is, the power supply is 50Hz/60Hz, and the equipment power consumption is 0.00~400.00Hz (arbitrarily set).
What are the Benefits of using ATO 1 Phase to 3 Phase vfd?
- Reduce energy consumption and energy costs: Optimize V/F curve automatically based on the load to realize power save running.
- Extend equipment life and reduce maintenance.
Note: The VFD does not contain a braking resistor. If you want to adding an external braking resistor, please confirm with us before placing your order.
(Braking resistor is only necessary if you intend to use the VFD for the machine tool and you want to stop it quickly at the same time.
In other cases, there is no need to use braking resistor, VFD itself can realize FREE STOP.)
