Are you looking for 12V 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 12V power supplies with different technologies from FEAS. Choose between unregulated (filtered / smoothed) 12V power supplies, linearly regulated or 12V switching power supplies (SMPS). Buy power supply units with a top hat 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.
► 12-volt power supply units - unregulated (sieved / smoothed)
The AC mains voltage is transformed by a transformer to the appropriate rectifier input voltage, which is then filtered and smoothed using an electrolytic capacitor. The output voltage may vary slightly depending on the AC input voltage and DC load. The construction of these 12V power supplies is robust and limited to the essentials. These 12V power supply units are sufficient for controlling valves, relays, contactors and Manget switches and for most PLC controls.
► 12-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 12VDC power supplies have a high level of control accuracy and fast settling times. These 12V power supplies are ideally suited for supplying high-quality electronic circuits where, among other things, low residual ripple is important.
► 12V Switched Mode Power Supply (SMPS)
The 12V switched-mode power supply also converts the mains voltage into a regulated 12VDC 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-like pulsating voltage using a pulse-width modulated semiconductor switch and transformed into the required 12V 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).
