About Compact 5W Power Module – MEAN WELL IOB-05:

Engineered for high efficiency and dependability, the IOB-05 Series provides a cost-effective power solution for industrial control, factory automation, smart home systems, and electronic instrumentation. This 5W open-frame module operates across a wide input range (85–305 Vac / 100–430 Vdc) and offers output voltages from 3.3V to 24V DC. With its compact 1" × 0.6" form factor and Class II safety design, the IOB-05 is ideal for direct installation on system PCBs, minimizing external component requirements and assembly time.

The IOB-05 ensures stable performance under harsh conditions with an extended -40°C to +85°C operating range and protection against short circuit, overload, over-voltage, and over-temperature faults. It achieves high energy efficiency (up to 81%) and maintains extremely low standby power consumption (<0.15W), supporting eco-friendly designs. Compliant with IEC62368-1 safety standards and EMC Class B emissions (with external components), it guarantees safe operation for industrial, telecom, and smart applications. Backed by a 3-year warranty, the MEAN WELL IOB-05 Series combines performance, safety, and compact design for modern power solutions.
