Are you looking for 30V switching power supplies for automation technology, machine control or measurement and control technology (MCR)?
Here you will find 30V switching power supplies (SMPS) for different input voltages from FEAS. Buy power supply units with extremely high protection class due to aluminium housing and full cast resin encapsulation. The 30VDC switching power supplies are available as cable version or terminal version, for mounting on top-hat rail, on the wall or for 19" rack.
Made in Germany: All power supply units are developed and manufactured in our factory in Ahrensburg near Hamburg according to the highest industrial standards.
► 30-Volt Switched Mode Power Supply (SNT) / Switched Mode Power Supply (SMPS)
The 30V switched-mode power supply also converts the mains voltage into a regulated 30VDC 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 30V 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).
► 30-VDC switching power supplies - with different input voltages
Select the appropriate input AC voltage range for your 30VDC switching power supply (85 - 270VAC or 320 - 550VAC).
