Power Adapter MEAN WELL DPU01N-12 1W Input 21.6-26.4V Output 15V

The MEAN WELL DPU01N-12 is a compact PCB-mount DC-DC converter designed for applications requiring a small, board-mounted power module. It accepts an input voltage between 21.6 and 26.4 VDC and provides a dual output of ±12 V at up to 0.042 A in a SIP through-hole package. The module is RoHS compliant and intended for reliable low-power supply tasks on printed circuit boards.

Advantages

The converter offers a compact SIP through-hole form factor suitable for PCB mounting, dual bipolar outputs (±12 V) for circuits that require both positive and negative rails, and a defined input range of 21.6–26.4 VDC that fits common intermediate bus voltages. Its low output current and 1 W class power make it appropriate for small signal circuits and bias supplies. RoHS compliance ensures it meets environmental material restrictions.

Suitable for

• Small signal and analog circuits requiring ±12 V bias rails
• Embedded systems and control boards with limited PCB space
• Low-power communication modules and sensor interfaces

How to use

Mount the DPU01N-12 into the PCB using the SIP through-hole pins and solder each pin to ensure reliable electrical and mechanical connection. Apply an input source within the specified 21.6–26.4 V DC range to the input pins, observing correct polarity. Use the ±12 V outputs to power downstream circuitry with current draw not exceeding 0.042 A per rail. Provide appropriate input filtering and decoupling on the PCB as required by your design to minimize noise and ensure stability.

Recommendations

For reliable operation, verify that the total load on each output does not exceed the rated 0.042 A, keep ambient temperature within the module's operating range as specified by MEAN WELL datasheets, and include local decoupling capacitors and adequate PCB creepage/clearance for your application's safety requirements.
