Product Code: PSEL-240
MPN #: MDS-350AD701
Losing data because your system powers down at the worst moment is frustrating. The Delta MDS-350AD701 350W, 12V Medical ATX 1U Power Supply delivers reliable 350 W of steady 12 V power, keeping computers, workstations and industrial controllers running smoothly without flicker or unexpected drops.
Many buyers worry about compatibility and safety when selecting a power supply for medical or industrial use. They often fear voltage spikes, insufficient output or lack of certifications. This unit removes those doubts with universal 90-264 Vac input, built-in active PFC and full IEC 60601-1 and IEC 62368-1 approvals, ensuring safe operation in demanding environments.
Ideal for medical equipment requiring type BF patient access, industrial controllers, and high-reliability workstations where uninterrupted 12 V power is critical.

We are retiring PICOPC Products MNHO-073, MNHO-048 and MNHO-043 and they have reached EOL (End Of Life) as we are introducing new products with better technology. We would recommend you to look into MNHO-095. For Untangle, pfSense, OPNsense, Windows 11, Proxmox VE etc. we recommend MNHO-095 whereas for Sophos, Kerio Control and Endian, we would recommend MNHO-069. (A complete list of supported OS can be found in each product's listing)
