The Mean Well IRM-30-12ST is a 30W single output AC-DC enclosed power supply that meets the 60950-1 (2nd Edition) international safety standards for IT equipment. The device features 12V DC single output voltage and has a built-in active PFC (Power Factor Correction) to improve power factor, reduce harmonic distortion and decrease the total harmonics distortion to less than 20%. It also features low no-load power consumption in both standby and off modes, as well as universal AC input from 85VAC to 264VAC. Its built-in over voltage, over current, short-circuit, over temperature, and overload protection make it safe and reliable for any application. The IRM-30-12ST is encapsulated by a rugged metal housing that protects against impact, dust, and corrosion and requires no additional cooling due to its full enclosed design.
