Τροφοδοτικό MEAN WELL SCWN03B-05 3W 5V είσοδος 18-36V

The MEAN WELL SCWN03B-05 is a DC-DC regulated single-output converter designed for applications requiring a compact, isolated power source. It accepts an input voltage range of 18–36 VDC and provides a stable 5 VDC output at up to 0.6 A (3 W). The module features 3000 VDC input-to-output isolation and comes in a DIP through-hole package suitable for PCB mounting. It is RoHS compliant.

Advantages

The SCWN03B-05 offers galvanic isolation of 3000 VDC between input and output, a wide input range that supports 18–36 VDC sources, and a compact DIP through-hole form factor for straightforward PCB installation. The converter provides regulated 5 VDC output at up to 0.6 A and meets RoHS environmental requirements.

Suitable for

• Embedded systems and control boards that require isolated 5 V supply
• Industrial applications with 18–36 VDC input rails
• PCB-mounted power modules in communication or measurement devices

Key specifications

• Model: MEAN WELL SCWN03B-05

How to use

Mount the SCWN03B-05 into the PCB using the DIP through-hole pins. Connect the DC input within the specified 18–36 VDC range to the input pins and take the regulated 5 VDC from the output pins. Observe correct polarity and ensure proper soldering and mechanical support. Provide adequate PCB layout and grounding to maintain isolation and minimize noise.

Recommendations

Use appropriate input filtering and transient protection on the 18–36 VDC supply, follow the manufacturer's recommended PCB layout for isolation spacing, and verify thermal conditions when operating near the maximum 0.6 A output to ensure reliable long-term performance.
