Power adapter/inverter MEAN WELL SCWN06C-03, input 36–72V, output 6W

The MEAN WELL SCWN06C-03 is a compact DC-DC regulated single output converter designed for low-power applications. It accepts a wide input range of 36–72 V DC and provides a stable 3.3 V DC output at up to 1.2 A, delivering 6 W of output power in a DIP through-hole package. The module features 3000 VDC input-to-output isolation and meets RoHS environmental requirements, making it suitable for embedded electronics, LED modules, and control circuitry where dependable low-voltage power conversion and galvanic isolation are required.

Advantages

The converter offers a wide input voltage window that accommodates varied supply conditions, a regulated single 3.3 V output for sensitive digital electronics, and 3000 VDC isolation for safety and noise rejection. Its through-hole DIP form factor simplifies mounting on PCBs and prototyping, while the small footprint and 6 W power rating allow integration into compact industrial and commercial devices. Compliance with RoHS indicates adherence to environmental standards.

Suitable for

• Powering microcontrollers, sensors and low-power embedded systems
• Supplying 3.3 V LED modules and small lighting drivers
• Providing isolated control circuit power in industrial automation
• Replacement or retrofit of DC-DC sections in commercial equipment

Key specifications

• Input voltage range: 36–72 V DC
• Output: 3.3 V DC regulated
• Output current: up to 1.2 A (6 W maximum)
• Isolation voltage: 3000 VDC between input and output
• Package type: DIP through-hole
• Power rating: 6 W
• RoHS compliant

How to use

Mount the module on a compatible PCB using the DIP through-hole pins, ensuring correct polarity on the input and output terminals. Connect a 36–72 V DC source to the input, and draw up to 1.2 A from the 3.3 V output while observing the rated power limit. Maintain adequate clearance and grounding as required by your system design to preserve the 3000 VDC isolation performance. Verify output voltage under load and add appropriate input/output filtering or transient protection if the application environment is electrically noisy.

Recommendations

Operate the converter within its specified input range and power rating, provide suitable heat dissipation and avoid continuous operation at absolute maximum current. Use proper isolation practices when integrating into safety-related or high-voltage systems and include fusing on the input side for protection against overcurrent events.
