Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•High-precision low-frequency phase module
•Adding first-stage phase amplification on the basis of the original one
•Can achieve signal phase within 500KHz
•Phase range: 0°~360°(default 1KHz low frequency)
•For high-frequency phase it needs to be replaced with corresponding capacitors
