The MEAN WELL SDR-75-48 is a high-performance 48V DIN rail power supply engineered for precision industrial applications where space efficiency and power reliability are critical. A primary strength of this unit is its 150% peak load capability, allowing it to provide up to 112.5W for 3 seconds to manage the high inrush currents typical of motorized or inductive loads. This capability ensures that the system remains operational during demanding startup phases without the need for a physically larger power source, maintaining a compact 32mm profile that maximizes available space on TS-35/7.5 or 15 DIN rails.

Designed for longevity in harsh environments, the SDR-75-48 operates within a broad temperature range of -30 °C to +70 °C using only natural air convection for cooling. It features a highly flexible voltage adjustment range of 48V to 55V, which is ideal for compensating for voltage drops over long cable runs in distributed control systems. The unit is built with industrial-grade protections, including automatic shutdown and recovery for over-temperature and short-circuit events, and holds UL 508 approval for industrial control equipment. Backed by a 3-year manufacturer warranty, it offers a stable and secure 48V energy solution for sensitive electronics and automation infrastructure.
