Information about the MEAN WELL SDR-240-48
The MEAN WELL SDR-240-48 represents a high-tier solution for industrial environments requiring a stable 48V DC output with superior energy management. This model is distinguished by its extraordinary efficiency of 94%, which significantly minimizes thermal loss and allows for a slim, fanless design that relies entirely on free air convection. A critical performance highlight is the 150% peak load capability, enabling the unit to provide up to 360W for a duration of 3 seconds. This surge capacity is essential for starting demanding inductive loads or handling sudden system requirements without triggering a premature shutdown or requiring a larger, more expensive power supply.
Engineered for maximum reliability, the SDR-240-48 includes built-in active PFC function to optimize power usage and meet strict industrial harmonic current standards. The mechanical design is optimized for the TS-35/7.5 or 15 DIN rail, featuring a compact 63mm width that saves valuable space in high-density control cabinets. For advanced system diagnostics, it is equipped with a DC OK relay contact, allowing for seamless integration of status monitoring into automation workflows. With a 3-year manufacturer warranty and UL 508 approval, this power supply is a robust choice for heavy industry, telecommunications, and sensitive electronic control systems.
