IRM-45 45W AC-DC Power Supply Modules MEAN WELL IRM-45 45W AC-DC Power Supply Modules achieve up to 90.5% efficiency and include models with a PCB-mount or screw-terminal style. These 45W miniature, single-output, encapsulated modules feature a universal input voltage range of 85VAC to 264VAC. The series withstands up to 5G anti-vibration demands while providing dust and moisture resistance as well as heat dissipation. The Class II modules are cooled by free-air convection and protect against short-circuit, overload, and overvoltage events while offering <,0.1W no-load power consumption. Ideal applications for MEAN WELL IRM-45 45W AC-DC Power Supply Modules include mechanical equipment, factory automation equipment, industrial electrical equipment, and handheld electronic devices.
