Alimentatore MEAN WELL SCWN03B-03 3W 0.6A ingresso 18-36V

The MEAN WELL SCWN03B-03 is a compact DC-DC regulated single output converter with an input voltage range of 18–36 VDC and a fixed output of 3.3 VDC at up to 0.6 A. Designed in a DIP through-hole package, it provides 3000 VDC input-to-output isolation and complies with RoHS requirements. Its small form factor and regulated output make it suitable for embedding into electronic equipment and industrial control circuits.

Advantages

The converter delivers a stable 3.3 V output with up to 0.6 A load current and offers high galvanic isolation of 3000 VDC between input and output. The wide input range (18–36 VDC) allows compatibility with varied DC supply systems. The DIP through-hole package simplifies PCB mounting and mechanical retention for prototyping and production runs. RoHS compliance ensures the unit meets environmental substance restrictions.

Suitable for

• Embedded electronics and low-power modules
• Industrial control and automation circuits
• Communication equipment and sensor interfaces
• Prototyping and small-volume PCB assemblies

How to use

Mount the SCWN03B-03 into a PCB using the DIP through-hole leads and ensure correct input polarity and adequate solder joints. Apply a DC input voltage within the specified 18–36 V range. Connect the regulated 3.3 V output to the load, ensuring the load current does not exceed 0.6 A. Provide appropriate PCB spacing and traces for isolation and routing according to your board design rules.

Recommendations

For reliable operation, keep the device within its rated input and output limits, provide proper cooling or ventilation in confined installations, and follow standard PCB creepage and clearance guidelines for 3000 VDC isolation. Verify connections before powering and consider input filtering if the supply is noisy.
