Mean Well IRM-03 Series 3 W Single Output Encapsulated AC-DC Power Supply

From Mean Well, the IRM-03 Series of encapsulated AC-DC power supplies are constructed from a phenolic 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-03 series is a 3 W miniature solution and is ready to solder straight onto PCB boards. Featuring a universal input voltage range of 85 V ac to 305 V ac, these AC-DC module power supplies are highly versatile. Featuring low no-load power consumption below 0.075 W and high efficiency up to 80%, these switching power supplies meet worldwide regulations for power consumption. IRM-03 power supplies are a Class II design and feature built-in EMI filtering components and excellent EMC filtering components that prevent electromagnetic interference.

Features and Benefits:

High efficiency up to 80% (depending on model) Isolation Class II
