MEAN WELL SLC03A-12 electric converter 3 W 9-18 V 250 mA

The MEAN WELL SLC03A-12 electric converter is a compact DC-DC module delivering 3 W of isolated power conversion. Designed for installations with limited space, it accepts a DC input range of 9–18 V and provides a regulated output current of 250 mA. Its small footprint and low profile allow integration into control panels, embedded systems, and portable equipment where stable low-power supply isolation and space efficiency are required.

Advantages

The converter combines a wide input voltage window with a stable output current, enabling reliable operation across varying supply conditions. Its compact mechanical dimensions reduce mounting area and permit placement on crowded PCBs or inside compact enclosures. The isolated output supports noise reduction and safety separation between input and output circuits, while the low power dissipation minimizes thermal management needs in constrained assemblies.

Suitable for

• Small embedded systems and single-board computers requiring isolated low-power rails
• Industrial control modules and instrumentation with limited PCB space
• Portable devices and battery-powered equipment operating in the 9–18 V range
• Signal conditioning circuits and sensor interfaces needing galvanic isolation

Key specifications

• Output power: 3 W
• Input voltage range: 9–18 V DC
• Output current: 250 mA
• Isolation between input and output: functional isolation for noise and safety separation
• Dimensions: approximately 13.8 mm (W) × 22.1 mm (D) × 8.55 mm (H)
• Low profile design suitable for compact installations

How to use

Mount the converter according to the mechanical constraints of the equipment, ensuring adequate clearance for connectors and airflow. Connect a suitable DC source within the 9–18 V range to the input terminals, and take the regulated output from the designated output terminals. Observe correct polarity on input and output connections. Provide grounding and creepage distances in line with your system’s safety requirements. Verify output current does not exceed 250 mA to prevent overload and ensure reliable operation.

Recommendations

For stable long-term performance, keep ambient temperature within the module’s operating range and avoid placing the converter adjacent to high-dissipation components. Use decoupling and proper filtering on both input and output lines if the application is sensitive to conducted or radiated noise. When used in battery-powered devices, select a battery and protection circuitry that maintain input voltage within the specified 9–18 V range under expected load conditions.
