Information about the MEAN WELL SDR-960-48
The MEAN WELL SDR-960-48 is a high-performance industrial power supply designed for DIN rail mounting, offering a robust 48V output at 20A. A standout technical achievement of this series is its 94% typical efficiency, which minimizes heat generation and allows the unit to operate reliably using only free air convection cooling. For applications involving heavy startup loads, the SDR-960-48 features a remarkable 130% peak load capability, providing up to 1248 Watts of power for 3 seconds. This overhead ensures that the system can handle temporary surges from motors or large capacitive banks without shutting down, maintaining operational continuity in complex industrial processes.
Despite its massive power output, the unit maintains a slim 110mm width, optimizing space on the TS-35 mounting rail. It is equipped with built-in active PFC to ensure compliance with harmonic current standards and features active current sharing functionality, allowing for the parallel connection of up to 4 units to reach a total output of 3840 Watts. Safety is paramount, as the unit is UL508 approved for industrial control equipment and includes a DC OK relay contact for integrated system monitoring. This combination of efficiency, surge power, and parallel scalability makes the SDR-960-48 an ideal choice for heavy-duty automation and large-scale industrial power distribution.
