precision AC purified AC regulated power supplies (voltage regulators) are new regulated power supplies (voltage regulators) that adopt internationally advanced sinusoidal energy distribution voltage stabilizing technology and integrate voltage stabilization and mains purification functions.                     
precision AC purified AC stabilized power supply (voltage stabilizer) not only has the advantages of high voltage stabilization accuracy, fast dynamic response speed, and small distortion, but also this stabilized voltage power supply (voltage stabilizer)
It is mainly used in computers, precision instruments, testing equipment, communication and broadcasting equipment, automatic control systems, etc. that require high power supply quality.
