Bloc d'alimentation MEAN WELL EDR-120-48

The MEAN WELL EDR-120-48 is an AC-DC industrial DIN-rail power supply that delivers 48V at up to 2.5A (120W). It accepts a wide input voltage range of 90–264V AC and comes in a compact metal enclosure (40 mm W × 113.5 mm D × 125.2 mm H). The unit is RoHS compliant and supplied in packs of 20, suitable for installations that require a stable, compact DIN-rail mounted power source.

Advantages

The EDR-120-48 provides regulated 48V output with protection features typical for industrial adapters, a space-saving metal case designed for DIN-rail mounting, and a wide input voltage range for global use. Its compact dimensions allow installation in control cabinets with limited space, and RoHS compliance ensures it meets common environmental standards.

Suitable for

• Industrial control cabinets and automation systems
• Terminal blocks and DIN-rail equipment requiring 48V DC
• Small servers, communication devices, or network accessories with 48V input
• Replacement or bulk installations (packs of 20 units)

How to use

Mount the MEAN WELL EDR-120-48 on a standard DIN rail inside the control cabinet. Connect the AC input to a suitably rated mains supply within 90–264V AC, observing local wiring regulations. Connect the 48V DC output to the load, ensuring polarity is correct and the total current draw does not exceed 2.5A. Provide adequate ventilation around the unit and avoid mounting near heat sources. Follow the manufacturer’s datasheet for detailed wiring diagrams and protection settings.

Recommendations

Use circuit protection (fuses or circuit breakers) on both the AC input and DC output as appropriate for your installation. Verify compatibility of connected devices with a 48V DC supply and plan for load distribution so individual units are not overloaded. For critical applications, consider redundancy or backup power arrangements.
