Why Choose ATO Single Phase VFDs? - Reduce energy consumption and costs - Increase production through tighter process control - Extend equipment life and reduce maintenance

How to Choose a Suitable VFD? When selecting a VFD, ensure that the rated current and power of the VFD are greater than those of the motor. It is recommended to choose a VFD with a capacity at least one level higher than the motor to provide a safety margin.

Wiring Methods for Single Phase Motor and VFD Connection: - Removing the motor capacitor - Keeping the motor capacitor

Applications of ATO Variable Frequency Drives: - Air conditioner load - Crusher load - Compressor load - Rolling mill load - Revolving furnace load

Note: Single-phase motors should not be operated at frequencies below 80% of their rated frequency for extended periods, as this may lead to motor failure.
