The 5” x 3” PCB size has dominated the PCB-type power supply market for many years and MEAN WELL also offers several models from 45W, 65W, 75W, 120W, 160W to 200W. To fulfill the requirements of miniature size and higher wattage applications, MEAN WELL has further introduced 300W high power density (14.5 W/in3) models~ RPS-300 and EPP-300 series, to provide end users a more complete choice for all kinds of applications. RPS-300 series units are designed to comply with international medical safety regulations (MOPP level) and characterized by its low leakage current (â‰¦300μA at 264VAC) that is suitable for “patient contact” equipment, which can fulfill the high quality demands of medical applications; while EPP-300 series, the industrial level PCB power supplies, are suitable to use in the IT systems and industrial machinery/electrical equipment.
Featuring built-in active PFC function and 90~264VAC full range input, RPS-300 and EPP-300 series’ are designed by up-to-date LLC topology and synchronize rectify technology. They possess up to 93% extremely high efficiency and can provide 200W continuously up to 50â„ƒ by free air convection only, (300W with 20.5CFM forced air), or operate under 70â„ƒ ambient temperature by suitable power derating. These two series are equipped with the function of 300VAC input surge immunity for 5 seconds, which can reduce the damage caused by unstable AC mains. Other standard functions include P.G./ P.F. signal output, built-in remote sensor, 12V/0.5A auxiliary output, protections for short circuit, overload, over voltage, and over temperature. Meanwhile, these two power units are equipped with built-in remote ON/OFF control and 5V/1A standby output to achieve the goal of “no load power consumption”.
