Purified and Stabilized Power Supply

Main Features: The JJW and JSW series single-phase and three-phase purified power supplies are AC regulated power supplies that integrate voltage stabilization and anti-interference capabilities. They not only feature high stabilization accuracy, high efficiency, fast response, high reliability, low noise, compact size, and light weight, but also effectively suppress voltage spikes and various noise interference in the power grid. They are widely used as ideal power supply equipment for computers, copiers, audio-visual equipment, medical devices, measurement instruments, industrial equipment, office equipment, electronic instruments, and automated control systems.
