Xi'an Jerrystar  Instrument Co.,ltd is a professional power supply manufacturer.We main produce the variable frequency power supply,voltage and frequency stabilization power supply,400HZ medium static frequency power supply,inverter power supply.

The variable frequency power supply can complete the AC-DC-AC conversion,and output the users' needed AC. Output the pure sine wave,output the frequency and output the voltage is adjustable in a certain range,and apply for any places need of the variable frequency and variable voltage.

The feature of the ideal AC power supply is frequency stabilization,voltage stabilization and the internal resistance is zero.The variable frequency power supply is very close to the ideal AC power supply,widely used in home appliance manufacturering,eletrical,eletronic manufacturng,IT industry,computer equipment,laboratories,aerospace and military unit,etc.
