Mean Well IRM-45 Series 45 W Single Output Encapsulated AC-DC Power Supply
From Mean Well, the IRM-45 Series of encapsulated AC-DC power supplies are constructed from a 94V-0 flame retardant plastic case and fully potted silicone. The construction meets anti-vibration demand up to 5G and provides resistance to dust and moisture while enhancing heat dissipation. The IRM-45 series is a 45 W single output compact solution and is ready to solder straight onto PCB boards. Featuring a universal input voltage range of 85 V ac to 264 V ac, these AC-DC module power supplies are highly versatile. Featuring low no-load power consumption below 0.1 W and high efficiency up to 90.5%, these switching power supplies meet worldwide regulations for power consumption. IRM-45 switch mode power supplies (SMPS) are a Class II design and include built-in EMI filtering components and excellent EMC features that prevent electromagnetic interference.
