Switching Power Supply 25 W 12 V DC – MEAN WELL S-25-12
The S-25-12 is a single output switching power supply 25 W / 12 V DC (“Single Output Switching Power Supply”) manufactured by MEAN WELL. It belongs to the S-25 series, featuring a universal AC input of 85–264 V AC (or 120–370 V DC) and a regulated output of 12 V DC / 2.1 A. It is documented as a component in CNC control cabinets, industrial automation systems, and electronic equipment in general. The unit is fanless (natural convection cooling) and compliant with CE/UL standards. The output voltage is adjustable via an onboard trimmer in the 10–13 V range; no significant revision variants exist in the standard version.
The S-25-12 provides the regulated 12 V DC auxiliary supply required to power logic boards, relays, transducers, displays, and other subsystems inside the CNC control cabinet. A failure results in loss of voltage across all 12 V circuits: the machine stops, drives lose their auxiliary supply, and the CNC cannot complete the enable sequence. In many control cabinets it is a critical, non-redundant component.
MEAN WELL is a Taiwanese switching power supply manufacturer founded in 1982, now one of the world’s leading suppliers with over 10,000 catalog models and worldwide distribution. The S-25 series is actively produced and widely available from major global electronics distributors.
