24 VDC output voltage

Here you will find 24V power supply units from FEAS for installation in electrical distribution boards with different technologies. Choose between unregulated (sieved / smoothed) 24V power supply units or 24V switched-mode power supply units (SMPS). Buy power supply units with top-hat rail.
Made in Germany: All power supply units are developed and manufactured in our factory in Ahrensburg.

Here, the AC mains voltage is transformed by a transformer to the appropriate rectifier input voltage, which is then filtered and smoothed by means of an electrolytic capacitor. Depending on the AC input voltage and DC load, the output voltage may vary slightly. The design of these 24V power supplies is robust and limited to the essentials. These 24V power supplies are sufficient for controlling valves, relays, contactors and Manget switches and for most PLC controls.

The 24V switched-mode power supply also converts the mains voltage into a regulated 24VDC 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 24V voltage required on the secondary side by means of a transformer. It is then rectified and filtered again. The power supply units with higher power ratings are all equipped with Power Factor Correction (PFC).
