RSP-3000 series – high power power supplies with programmable output from MEAN WELL


The development of modern technologies (industrial equipment, laser installations, digital telecommunications and other applications) increasingly requires the use of high–power DC sources with an output voltage from the standard range - 12, 24 or 48V. One of the most popular series with high power output and advanced functionality is the RSP series.

The power supplies of the RSP-3000 series are AC/DC converters in a case design designed for embedding in end devices of high power (3000 W) with a DC voltage output from the standard range of 12, 24, 48V. The RSP-3000 series is distinguished by its advanced functionality – adjustment (programming) of the output voltage within a wide range (from 10 to 110% of the nominal level), a parallel connection function to increase the output power of Current Sharing (up to 9000W, according to the 2+1 scheme), remote on/off, output status monitoring (DC OK signal), and an additional 12V DC output (for remote on-off function).

The power supplies of the RSP-3000 series have a built-in power Factor Corrector (PFC), the function of limiting the output current (Constant current limiting), high efficiency up to 91.5%, the main types of protection: short circuit, overload, overvoltage, overheating. The RSP-3000 power supplies use forced ventilation due to the built-in cooling fan. The RSP-3000 series power supplies have a warranty period of 5 years. The efficiency of the power supply remains maximum in a wide range of load changes (for example, RSP-3000-48):

The applications of power supplies of the RSP-3000 series are quite wide – laboratory installations, test and measuring equipment, industrial equipment, laser installations, digital broadcasting systems, radio transmitting and receiving devices and others.
