Power supplies with 14 VDC output voltage
Are you looking for 14V power supply units for control cabinets, sub-distribution, as a UPS or buffer module for machine control or measurement and control technology?
Here you will find 14VDC power supply units with different technologies from FEAS. Choose between linear regulated 14V power supplies or 14V switched-mode power supplies (SMPS). Buy power supply units with top-hat rail or power supply units with extremely high protection class.
Made in Germany: All power supply units are developed and manufactured in our factory in Ahrensburg.
► 14-volt power supply units - linear regulated
To provide an unregulated transformer power supply with a regulated output voltage, a transistor regulation circuit is implemented. The high voltage stability and the extremely low residual ripple are bought here by an unfavourable efficiency compared to other concepts. Linear regulated 14VDC power supplies have a high control accuracy and fast settling time. These 14V power supplies are excellently suited for supplying higher-quality electronic circuits where, among other things, low residual ripple is important.
► 14V Switched Mode Power Supply (SMPS)
The 14V switched-mode power supply also converts the mains voltage into a regulated 14VDC output voltage, but has a higher efficiency and a smaller size. After filtering and rectification, the AC input voltage is converted into a high-frequency wave-shaped pulsating voltage by a pulse-width modulated semiconductor switch and transformed to the 14V voltage required on the secondary side by means of a transformer. It is then rectified and filtered again. The power supply units of higher power are all equipped with a Power Factor Correction (PFC).
