Power supply units with high protection class (IP65/IP68) and 48 VDC output voltage

Are you looking for 48V power supply units (IP65/IP68) with a particularly high degree of protection?

Here you will find powerful and particularly robust 48V switched-mode power supply units (IP65/IP68) for harsh industrial environments. FEAS offers power supply units of different technologies as cable versions. Thanks to full casting resin encapsulation and reliably sealed cable inputs and outputs and LEDs, all these power supplies meet the requirements of classes IP65 to IP68K.

Made in Germany: All power supply units are developed and manufactured in our factory in Ahrensburg.

48-volt power supply units (IP65/IP68) - unregulated (filtered/smoothed)

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 consumer, the output voltage may vary slightly. The design of these 48V power supply units (IP65/IP68) is robust and limited to the essentials. These 48V power supplies (IP65/IP68) are sufficient for controlling valves, relays, contactors and magnetic switches and for most PLC controls.

48V switching power supplies - SMPS (IP65/IP68)

The 48V switching power supply (IP65/IP68) converts the mains voltage into a regulated 48VDC 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 into the required 48V voltage by means of a transformer on the secondary side. It is then rectified and filtered again. The power supply units of higher power are all equipped with a Power Factor Correction (PFC).
