Information about the MEAN WELL SDR-480P-48

The MEAN WELL SDR-480P-48 is a high-performance industrial DIN rail power supply engineered for applications requiring high efficiency and robust power reserves. A standout feature of this unit is its 150% peak load capability, allowing it to provide up to 720W for 3 seconds. This is particularly critical for starting inductive loads or handling sudden surges in industrial machinery without the need for an oversized power supply. Operating at a 94% efficiency rating, it minimizes energy waste and heat generation, ensuring stable performance within a slim 85.5mm wide chassis.

Designed for scalability and reliability, the SDR-480P-48 supports active current sharing, enabling the parallel connection of up to eight units for a combined output of 3840W. It features a comprehensive suite of protections, including auto-recovery for over-voltage and thermal shutdowns if temperatures exceed 105°C. The integration of a DC OK relay contact allows for seamless remote monitoring of the power status. Certified to UL 508 standards and featuring a built-in active PFC function, this unit is an ideal choice for complex automation, control systems, and heavy-duty industrial environments.
