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 main use case for the Mean Well IOB-05-09?

The IOB-05-09 is an AC-DC on-board power module designed to be assembled directly on a system PCB. It is suited to compact embedded equipment that needs a regulated 9V output from a wide AC or DC input range.

What are the key electrical ratings of the IOB-05-09?

This model is rated for 5.04W output power and provides a 9V DC output. Its rated output current is 0.56A, and ripple and noise are specified at 150mV.

What input range does the Mean Well IOB-05-09 support?

The module accepts a wide input range of 85 to 305Vac and 100 to 430Vdc. That broad range makes it suitable for equipment intended for varied global power environments.

Can the IOB-05-09 operate in demanding temperature conditions?

Yes, the IOB-05-09 is specified for operation from -40°C to +85°C. This wide operating range makes it a practical choice for equipment exposed to cold starts or elevated ambient temperatures.

What protection features are built into the IOB-05-09?

The module includes short circuit, overload, and over-voltage protection. Short circuit protection uses continuous automatic recovery in hiccup mode, and overload protection recovers automatically after the fault condition is removed.

Why would a buyer choose the IOB-05-09 for space-constrained designs?

The IOB-05-09 is built in a compact 26.4 x 14.73 x 11mm package, approximately 1.039 x 0.579 x 0.433 inches. Its small 1 x 0.6 inch class footprint and free-air convection cooling help it fit applications where board space is limited.
