Are you looking for 5V power supplies for control cabinets, sub-distributions, as UPS or buffer module for machine control or measurement technology and control technology?
Here you will find 5V power supplies with different technologies from FEAS. Choose between linearly regulated power supplies or 5V switched-mode power supplies (SMPS). Buy power supply units with DIN rail or power supply units with an extremely high degree of protection.
Made in Germany: All power supplies are developed and manufactured in our factory in Ahrensburg.
► 5-volt power supply units - linearly regulated
A transistor control circuit is implemented to provide an unregulated transformer power supply with a regulated output voltage. The high voltage stability and the extremely low residual ripple are bought at the price of an efficiency that is unfavorable compared to other concepts. Linearly regulated 5VDC power packs have a high level of control accuracy and fast settling times. These 5V power supply units are ideally suited for the supply of high-quality electronic circuits where, among other things, low residual ripple is important.
► 5V Switched Mode Power Supply (SMPS)
The 5V switched-mode power supply also converts the mains voltage into a regulated 5VDC output voltage, but has a higher degree of efficiency and a smaller size. After filtering and rectification, the AC input voltage is converted into a high-frequency, wave-shaped pulsating voltage using a pulse-width modulated semiconductor switch and transformed into the required 5V voltage on the secondary side by using a transformer. It is then rectified and filtered again. The higher-performance power supply units are all equipped with Power Factor Correction (PFC).
