An ultra-low noise/low noise AC-DC switching power supply suitable for replacing linear power supplies!

Our "Ultra Low Noise Power Supply Series" achieves the compactness, lightweight, and high efficiency characteristic of switching power supplies while maintaining noise performance equivalent to linear power supplies. This significantly reduces the man-hours required for noise countermeasures across the entire customer system and alleviates the burden on design. It can be widely used from measurement and analysis equipment to semiconductor manufacturing equipment. 【Features】 ■ Ultra-low output ripple noise of 1mV (RFS series) ■ Super low output ripple noise of 10mV (LFS, PFS series) ■ Low noise terminal voltage (input feedback noise), low noise electric field strength (radiated noise) ■ Low leakage current ■ Significant reduction in output common mode noise (RFS series) *For more details, please refer to the PDF document or feel free to contact us.
