ZUS252412 Cosel DC-DC Converter
ZUS252412 DC-DC Converter – Cosel ZUS25
The ZUS252412 from Cosel is a 25W isolated DC-DC converter designed for demanding industrial and commercial power electronics. With an input voltage range of 18-36 VDC and delivering a 12 V, 2.1 A output, it’s built for robust performance in systems like control units, instrumentation, ITE equipment, and embedded designs. Its six-DIP package, slim profile, and built-in protections make it a strong fit where size, safety, and efficiency are critical.
Durability and efficiency are central to the ZUS252412’s design. It offers about 85% typical efficiency, with built-in remote ON/OFF control, overcurrent and overvoltage protection, and solid isolation of 500 VDC input-to-output. These features help reduce power waste, manage thermal stress, and protect downstream electronics in harsh or variable conditions.
Though officially discontinued, the ZUS252412 remains widely used by OEMs and maintenance teams as a replacement or in redesigns requiring a narrow input range, isolated 12 V supply, and high reliability. Its established supply chain and multiple distributor listings ensure it is still accessible for repairs and legacy systems.
