MEAN WELL Introduces New Enclosed Type Switching Power Supply

Mean Well Ent. Co. Ltd. has introduced the RSP-1000 series – a 1000W enclosed type switching power supply with power factor correction (PFC) and parallel function – for the 1U low profile and high wattage applications. Featuring 10.67W/in3 extremely high power density, RSP-1000 series can provide rated output wattage even at 100Vac input because of its high efficiency design. RSP-1000 also has the built-in trimming function that the output voltage can be adjusted between 40 and 110% rated value by adding an external voltage source or resistors.

Besides the standard functions of remote sense, remote ON/OFF control, 5V/0.5A auxiliary output, and dc OK signal, the RSP-1000 series uses constant current limiting as the over load protection which will be good for applications of capacitive/inductive load. If more power is needed, the built-in active current sharing function can greatly fulfill high wattage demands that up to 3 units can be connected in parallel. In the mean time, because of the miniature design, only a very small space in the system will be occupied in comparison to many products with similar wattage. Applications include front-end power system, factory automation, instrumentation, moving sign, telecom/datacom, where space is limited and high efficiency is required.

Among the features and main specifications of the RSP-1000 series are: a 1U low profile; high power density 10.67W/in3; universal ac input/full range; built-in active PFC circuit compliance to EN61000-3-2; short circuit, overload, over-voltage, over-temperature protection; built-in remote ON/OFF control and remote sense; output voltage can be trimmed between 40~110% rated output voltage; dc OK signal output; built-in active current sharing; built-in 5V/0.5A auxiliary output; high efficiency up to 90%; dimensions of 295mm x 127mm x 41mm; and UL/CUL/TUV/CE/CB certificates.
