Power Adapter MEAN WELL SD-15C-5

The MEAN WELL SD-15C-5 is an enclosed DC‑DC converter designed for applications requiring a stable 5 Vdc output from a 36–72 Vdc input. Delivering up to 3 A (15 W) with free-air convection cooling, this compact power adapter measures 51 × 78 × 28 mm and is RoHS compliant.

Advantages

The SD-15C-5 provides a regulated 5 V output with a wide input range, enabling use with various 36–72 V sources. Its enclosed construction and small footprint simplify integration into control panels and equipment. Free-air convection cooling removes the need for forced ventilation in many installations, and RoHS compliance ensures restriction of hazardous substances.

Suitable for

• Industrial control systems and PLC modules
• Telecom and networking equipment with 36–72 Vdc supplies
• Embedded devices and instrumentation requiring 5 V power
• Battery-powered or vehicle systems with high-voltage DC rails

Key specifications

• Input voltage: 36–72 Vdc
• Output voltage: +5 Vdc
• Output current / power: 3 A / 15 W
• Cooling: free-air convection
• Dimensions: 51 × 78 × 28 mm

How to use

Mount the enclosed DC‑DC converter in a location with adequate airflow and secure electrical connections to the 36–72 Vdc input and the 5 Vdc output terminals. Observe correct polarity and wiring practices. Ensure the ambient temperature and mounting orientation follow the manufacturer's installation guidance to maintain rated output current and to avoid overheating.

Usage recommendations

For reliable operation, avoid enclosing the unit in tightly sealed compartments without ventilation, and keep the converter within its specified input range. Verify system inrush and startup conditions to prevent transient overloads, and provide appropriate fusing on the input side.
