Power adapter/inverter MEAN WELL SMU02M-12, Input 10.8–13.2 V, Output 12 V, Output power 2 W

MEAN WELL SMU02M-12 is a compact unregulated DC-DC converter in a SIP package that provides a fixed 12 V output with up to 0.167 A (2 W) output power. It accepts input voltages from 10.8 to 13.2 V and offers 1500 VDC input-to-output isolation. The module is RoHS compliant and intended for low-power electronic devices and embedded systems requiring a small, reliable 12 V supply.

Advantages

The converter combines a small SIP package with galvanic isolation of 1500 VDC and a simple unregulated single 12 V output, making it space-efficient and easy to integrate. Narrow input range optimized for 12 V vehicle or battery systems reduces the need for additional conditioning. Low power rating (2 W) and fixed output simplify selection for basic 12 V loads while meeting RoHS environmental requirements.

Suitable for

• Low-power industrial control modules
• Automotive and battery-powered equipment with 12 V input
• Embedded systems and sensors requiring isolated 12 V supply
• Small instrumentation and communication modules

Key specifications

• Manufacturer: MEAN WELL
• Model (MPN): SMU02M-12
• Input voltage: 10.8–13.2 V
• Output voltage: 12 V DC
• Output current: 0.167 A (max)
• Output power: 2 W
• Isolation (I/O): 1500 VDC
• Package: SIP
• RoHS: compliant

How to use

Connect the input to a stable 10.8–13.2 V DC source with correct polarity, and connect the output to the 12 V load, observing the maximum output current of 0.167 A. Mount the SIP package according to the PCB footprint and maintain adequate spacing for isolation. Because the converter is unregulated, allow for input voltage variation when sizing the load and any downstream circuitry.

Recommendations

Use the SMU02M-12 where compact isolated 12 V power is required for low-current devices. Verify that your load does not exceed 2 W and that the input supply remains within 10.8–13.2 V. For sensitive electronics, add downstream regulation or filtering if a tightly regulated voltage is needed.
