Power adapter MEAN WELL MDS01N-12 1 W 12 V Input 21.6-26.4 V

The MEAN WELL MDS01N-12 is a compact DC-DC medical converter designed for PCB-mounting in a SIP through-hole package. It accepts an input voltage between 21.6 and 26.4 V DC and provides a single 12 V DC output at up to 0.084 A (1 W). The module offers enhanced safety isolation with 2xMOPP suitable for medical applications and is RoHS compliant.

Advantages

The converter's small SIP form factor saves PCB space and allows straightforward through-hole mounting. Low power consumption and a stable 12 V output make it suitable for low-power devices. The 2xMOPP isolation rating provides increased patient and operator protection in medical environments while RoHS compliance ensures reduced hazardous substances.

Suitable for

• Low-power medical electronics and monitoring devices
• Embedded systems and PCB-integrated power rails
• Instrumentation and sensor modules requiring isolated 12 V supply

When it may not be suitable

This converter supplies only 1 W (12 V at 0.084 A), so it is not suitable for applications that require higher currents or power-hungry loads. Because it is a PCB-mounted SIP through-hole module, it may not be appropriate for systems that need fully enclosed external adapters or connectors for frequent user access.

Key specifications

• Input voltage: 21.6–26.4 V DC
• Output voltage: 12 V DC
• Output current: up to 0.084 A (1 W)
• Mounting: SIP through-hole (PCB mount)
• Isolation: 2×MOPP (medical isolated)
• Compliance: RoHS

How to use

Solder the SIP through-hole pins to the PCB according to the manufacturer’s recommended footprint and ensure proper creepage and clearance on the board. Apply an input voltage within 21.6–26.4 V DC and verify the 12 V output under the expected load. Observe standard medical-device assembly procedures and insulation requirements to maintain the 2×MOPP isolation performance.

What to consider before purchase

• Required output power and current — rated at 1 W (0.084 A) only
• Physical mounting style — SIP through-hole for PCB assembly
• Input voltage availability in your system (21.6–26.4 V DC)
• Required isolation level for medical applications (2×MOPP)

Usage recommendations

Use this module on PCBs for low-power medical or embedded designs where isolated 12 V is needed; ensure input voltage stability and follow board layout and insulation guidelines to preserve isolation and thermal performance.
