Servo electronic transformer can only be used for servo drive, can also be used in which, and ordinary winding transformer what is the difference between

The winding transformer output voltage is in the form of sine wave output, and electronic transformers are mostly in the form of square wave output voltage or square wave synthesized sine wave form output, the two have essential differences. Some devices can only use sine wave voltage, our company's servo drive can use both sine wave and square wave voltage, but the fan on the servo drive can only be equipped with sine wave voltage. So generally we do not recommend users to use electronic transformers. Electronic transformers are low cost and prone to failure.
