The IRM-45-5 is a miniature, 40W AC-DC module-type power supply designed to be soldered directly onto PCB boards. It accepts a universal input voltage from 85 to 305VAC and delivers a 5V DC output with a rated current of 8A. Key electrical characteristics include a low ripple and noise of 80mVp-p, a voltage tolerance of ±2.5%, and an efficiency of 83.5%. Cooled by free air convection, this module features built-in protections for short circuit, overload, and over voltage, making it suitable for industrial electrical equipment, factory automation, and handheld electronic devices.
