Test conditions and notes5

1.All parameters NOT specially mentioned are measured at 230Vac input, rated load and 25℃ of ambient temperature.
2.Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
3.Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
4.When starting at a low temperature of -40℃, the output capacitor needs to be equipped with a solid capacitor to meet the load reduction curve requirements.
5.The final equipment must be re-confirm that it still meet EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”(as available on http://www.meanwell.com)

FAQ

What is the Mean Well IOB-05-05 designed for?

The Mean Well IOB-05-05 is a 5W AC-DC on-board power module designed to be assembled directly on a system's main PCB. It provides a regulated 5V output at up to 1A in a compact module format for embedded and space-constrained equipment.

What are the main electrical ratings of the IOB-05-05?

This model is rated for 5W total output power and delivers 5V DC at 1A. It accepts a wide 85 to 305Vac input range, and also supports 100 to 430Vdc input according to the provided specification.

Is the IOB-05-05 suitable for harsh temperature environments?

Yes, the IOB-05-05 is specified for operation from -40C to +85C. That wide operating range makes it relevant for industrial and enclosed equipment designs where ambient conditions can vary significantly.

What protection features are included in the Mean Well IOB-05-05?

The module includes short circuit, overload, and over voltage protection. Short circuit and overload protection use automatic recovery behavior, while over voltage protection is implemented with an output voltage clamp.

How compact is the IOB-05-05 compared with larger enclosed power supplies?

The IOB-05-05 is much smaller than typical enclosed or chassis-style power supplies, with dimensions of 26.4 x 14.73 x 11mm. Its 1 x 0.6 inch class footprint is intended for applications where board space is limited and a low-profile embedded power solution is preferred.

What compliance and operating characteristics matter for OEM buyers evaluating this model?

The IOB-05-05 is listed as Safety Class II and approved to IEC62368-1 under LVD. It also has no-load power consumption below 0.15W and uses free air convection cooling, which can be relevant when selecting modules for efficient compact equipment.
