Strømforsyning MEAN WELL DDR-240B-48

The MEAN WELL DDR-240B-48 is an ultra-slim industrial DC-DC DIN-rail converter that accepts an input voltage range of 16.8–33.6 V DC and provides a single 48 V DC output rated at 5 A (240 W). The compact adapter measures 40 mm (W) x 113.5 mm (D) x 125.2 mm (H) and is RoHS compliant, making it suitable for installations with limited space where a stable 48 V supply is required.

Advantages

The DDR-240B-48 offers a high power density in a narrow enclosure, reliable voltage conversion for industrial environments, and RoHS compliance for reduced environmental impact. Its DIN-rail form factor allows straightforward mounting in control cabinets and distribution panels, while the wide input range supports operation from various DC sources.

Suitable for

• Industrial control cabinets and automation systems
• Telecommunications and network equipment requiring 48 V
• Battery-powered systems and DC bus applications
• Space-constrained electrical panels and DIN-rail installations

How to use

Mount the converter on a standard DIN rail inside the control cabinet and connect the DC input to a suitable 16.8–33.6 V source observing correct polarity. Connect the 48 V output to the load, ensuring the current does not exceed 5 A and that wiring and fusing comply with local electrical standards. Allow adequate ventilation around the unit and verify connections before powering the system.

Recommendations

For reliable long-term operation, use appropriate input protection (fuses or circuit breakers), keep the ambient temperature within the manufacturer's specified range, and avoid placing the unit directly next to heat-generating components. Verify compatibility with your system's grounding and transient protection requirements.
