RSP-350 AC To DC Power Supply With PFC

The WEHO RSP-350W is a robust 350W single-output enclosed power supply designed for high performance and reliability. It operates with a universal AC input from 90V to 264V and also supports a DC input range of 135V to 370V. This model is engineered to withstand a 300VAC surge input for up to five seconds, adding to its durability. A key feature of the RSP-350W is its built-in active Power Factor Correction (PFC), which enhances efficiency—reaching up to 94% depending on the specific model.
This series is available in various DC output voltages, including 12V, 24V, 36V, and 48V, to cater to a wide array of industrial applications. Housed in a compact, low-profile 30mm enclosure, its dimensions are 215 x 115 x 30mm. The RSP-350W is equipped with comprehensive protections against overload, overvoltage, and over-temperature, ensuring safe and consistent operation. Cooling is managed by a built-in fan, and it can operate in temperatures ranging from -20°C to +60°C. These features make the RSP-350W an ideal power solution for industrial control systems, instrumentation, and automation equipment.
