Fonte de alimentação MEAN WELL NID35-15, 35 W, entrada 20–53 V, saída 15 V, RoHS, dimensões compactas

MEAN WELL NID35-15 is a compact 35 W DC-DC converter designed for PCB-mount applications that require a regulated 15 V output from a wide 20–53 V input range. The non-isolated, open-frame SIP package provides a space-saving solution for embedded systems, industrial controls and small electronic modules. With a rated output current of 2.4 A and a remote ON/OFF function, this converter is intended for installations where reliable 15 V power and minimal board footprint are important.

Advantages

The converter combines a wide input voltage range and a stable fixed 15 V output to simplify system power design. Its SIP package and compact dimensions allow easy PCB mounting in constrained spaces, while the non-isolated topology reduces component count and improves efficiency in applications that do not require galvanic isolation. The remote ON/OFF feature enables straightforward power sequencing and control from system logic.

How to use

Mount the SIP package on the PCB following the manufacturer recommended footprint and ensure good solder joints for reliable thermal and electrical contact. Connect an appropriate 20–53 V DC input source to the input pins and observe polarity. Use the remote ON/OFF pin driven by system logic or pull it to the specified level to enable or disable the output. Provide adequate decoupling and filtering at the 15 V output to meet the downstream device requirements and follow PCB layout guidelines to minimize noise and ensure stable regulation.

Recommendations

For reliable operation, keep ambient temperature within the converter's rated range, provide sufficient airflow or heatsinking on the PCB if operating near the full 35 W rating, and avoid using the module where galvanic isolation is required. Verify output filtering and transient response against the connected load and follow EMC layout practices to reduce conducted and radiated emissions.
