MEAN WELL Switching Power Supply, IRM-01-3.3S, 3.3V dc, 300mA, 1W, 1 Output, 120 → 430 V dc, 85 → 305 V

From Mean Well, the IRM-01 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-01 series is a 1 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 77%, these switching power supplies meet worldwide regulations for power consumption. IRM-01 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.

High efficiency up to 77% (depending on model)

Suitable applications include hand held electronic devices, factory automation equipment, mechanical equipment and industrial electrical equipment.
