Power adapter/inverter mean well SMU02N-15, input 21.6–26.4 V, output 15 V, 2 W

Mean Well SMU02N-15 is a compact DC‑DC converter in a SIP package providing a single unregulated output of 15 V at up to 0.133 A (2 W). It accepts an input range of 21.6–26.4 V and features 1500 VDC input-to-output isolation. The module is RoHS compliant and supplied in bulk packs, suitable where a small, isolated 15 V supply is required for low‑power electronics and embedded systems.

Advantages

The SMU02N-15 offers galvanic isolation of 1500 VDC between input and output, a compact SIP form factor for space‑constrained designs, and a stable 15 V output suitable for low‑power loads up to 2 W. Its wide input tolerance within the specified 21.6–26.4 V range makes it compatible with common 24 V systems, and RoHS compliance ensures suitability for restricted‑substance environments.

Suitable for

• Low‑power electronic modules and sensors
• Signal conditioning circuits
• Embedded systems and controllers requiring isolated 15 V
• Industrial 24 V backplane applications

How to use

Connect the converter input to a stable DC source within 21.6–26.4 V, observing correct polarity. Mount the SIP package according to your PCB layout and solder or socket it per the manufacturer’s footprint recommendations. Ensure the output load does not exceed 0.133 A and allow for adequate clearances for the 1500 V isolation. No external regulation is provided; if precise output regulation is required, use an additional regulator or design margin into the load.

Recommendations

Operate the SMU02N-15 within the specified input range and current limit, provide proper PCB creepage and clearance for isolation, and avoid exposing the module to temperatures or mechanical stresses beyond the manufacturer’s ratings to ensure reliable long‑term operation.
