UL/CUL/TUV/CB/CE. 5. Mean Well RST-5000 Series 5000W AC-DC Enclosed Switch Mode Power Supply. The Mean Well RST-5000 is a series of single output industrial switch mode power supplies, with built-in PFC function and wide range 3-phase AC input, providing outputs of 24 and 48 Vdc, the most frequently-used DC voltage in the industrial application field. The RST-5000 has an high efficiency of up to 91% and thanks to the built-in fan can provide full load output under 50°C ambient temperature. Other features of this industrial power supply are the remote sense function, the remote ON/OFF control, the 12V/0.1A auxiliary power, the alarm signal output for AC fail, DC ok, fan fail and over temperature protection. Ideal applications of the RST-5000 switch mode power supply are in automation equipments, industrial control equipments, laser engravers, telecommunication systems and any applications which need high operating power. 3-phase AC input Built-in active PFC function High efficiency up to 91% Output Voltage can be trimmed 20 120% of rated voltage by 1 6VDC external control signal Output current can be trimmed 20 100% of rated current by 1 5VDC external control signal Built-in parallel function Forced air cooling by built-in fan with speed control function Built-in remote ON/OFF control and remote sense function Alarm signal output: AC fail, DC OK, fan fail, over temperature protection Built-in 12V/0.1A auxiliary output for remote control Short circuit / Over voltage / Over temperature / Overload protections
