MEAN WELL SLC03A-05 electric converter 3 W 9-18 V 600 mA

The MEAN WELL SLC03A-05 electric converter is a compact DC‑DC module rated for 3 W continuous power. It accepts a DC input voltage between 9 and 18 V and delivers a regulated output current up to 600 mA. Its very small footprint—13.8 mm wide, 22.1 mm deep and 8.55 mm high—allows installation in tight spaces and inside compact electronic assemblies where a stable low‑power DC supply is required.

Advantages

The converter combines a low-power design with a wide input voltage range to provide stable output current for LEDs, sensors and low-power modules. Its compact mechanical dimensions reduce space requirements and simplify integration on small PCBs or inside housings. Built with established MEAN WELL engineering, the unit aims for reliable performance under typical operating conditions and straightforward thermal behavior given its power class.

Suitable for

• LED driver applications requiring constant current up to 600 mA
• Powering sensors and interface modules in battery or vehicle systems with 9–18 V supplies
• Embedded electronics and small control boards with limited installation space
• Prototyping and small-scale industrial devices where 3 W supplies are sufficient

Key specifications

• Output power: 3 W
• Input voltage range: 9–18 V DC
• Output current: 600 mA (regulated)
• Mechanical dimensions (W × D × H): 13.8 mm × 22.1 mm × 8.55 mm
• Form factor: compact PCB-mountable DC‑DC converter

How to use

Connect the converter input to a stable DC source within the specified 9–18 V range, observing correct polarity. Route the output to the load that requires a regulated current of up to 600 mA. Ensure that PCB mounting and adjacent components allow sufficient clearance for heat dissipation. Verify input and output connections with a multimeter before applying power and monitor temperature during initial operation to confirm stable behavior under expected load conditions.

Recommendations

For reliable operation, operate the module within the specified input voltage range and avoid continuous loading beyond the rated current. Provide adequate ventilation or thermal coupling to a chassis if the converter is enclosed. Use appropriate input filtering and transient protection where the supply source is noisy or exposed to load dumps, and ensure compliance with the end application’s safety and EMC requirements.
