Description
The new RS-75 Series are 20% smaller than their 75W counterpart and are our most miniature AC/DC enclosed type switching power supplies that can provide 75W by only free air convection. RS-75 is fully RoHS compliant and all the electrolytic capacitors in the unit are rated in 105°C. RS-75 can also withstand 300VAC input surge for 5 seconds and 5G vibration meaning that is suitable for operation in harsh environments. Full output wattage can be provided up to 50°C and the highest operating temperature is as high as 70°C, with certain de-rating. Other standard functions include short circuit, overload, over voltage, and over temperature protections.
