MEAN WELL Switching Power Supply 48V DC, 254W, 5.3A Output, Chassis Mount RPS-400-48-C

MEAN WELL RPS-400-48-C switching power supply offers a robust 48V DC output with a maximum power rating of 254 watts and an output current of 5.3A. This chassis mount power supply operates efficiently within a wide temperature range from -30°C to 70°C, making it suitable for various industrial and medical environments.

Designed to meet international medical safety standards including 2 x MOPP isolation between primary and secondary circuits, the RPS-400-48-C is ideal for sensitive applications such as oral irrigators, hemodialysis machines, medical monitors, sleep apnea devices, pump machines, and electric beds. Its high efficiency of 94% ensures energy savings and reduced heat generation.

The unit supports a universal AC input voltage range with a minimum of 80V AC and a maximum of 264V AC or 370V DC, featuring a built-in power factor correction (PFC) function. Protection features encompass short circuit, overload, overvoltage, and over-temperature safeguards, enhancing reliability and safety during operation.

Cooling is achieved through free air convection for power ratings up to 250W and 400W models with 25CFM forced air. Additionally, the power supply has a built-in remote sense function and provides a standby 5V output at 1A with the fan running or 0.6A without the fan. A power-on LED indicator allows for easy status monitoring.

This power supply’s dimensions are compact at 130mm length, 43mm width, and 43mm depth, weighing 510 grams, facilitating installation within tight spaces. It complies with standards such as UL 62368-1, IS 13252(Part1)/IEC 60950-1, CSA C22.2 No. 62368-1, CCCGB4943.1, BSMI CNS143361, AS/NZS 62368.1, and TUV BS EN/EN 62368-1, ensuring broad acceptance across regulatory regimes.
