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 type of applications is the Mean Well IOB-15-05B best suited for?

The IOB-15-05B is designed for embedded power use inside OEM and industrial equipment where a compact on-board AC-DC module is preferred. It is a practical fit for space-constrained control boards, monitoring devices, and other PCB-based systems that need a low-power isolated supply.

What input range does the IOB-15-05B support?

This model supports a wide 85 to 305Vac input range and also accepts 100 to 430Vdc. That broad range makes it suitable for equipment intended for global input conditions rather than a single local mains standard.

Is the IOB-15-05B a good choice for compact product designs?

Yes. Mean Well specifies this module as an on-board type power supply with a compact 44.5 x 25.5 x 15 mm body, making it suitable where PCB area and enclosure space are limited. Its vertical form factor also helps when height and layout matter in dense assemblies.

Can the IOB-15-05B operate in harsh temperature conditions?

This model is rated for a wide operating temperature range of -40 to +85 C, subject to the manufacturer's derating guidance. That makes it better suited than many general-purpose modules for equipment exposed to cold starts or elevated internal temperatures.

What protection features are included on the IOB-15-05B?

The IOB-15-05B includes short circuit, overload, and overvoltage protection. Mean Well specifies automatic recovery behavior, with hiccup-mode protection for short circuit and overload conditions and output-voltage clamp protection for overvoltage.

How efficient is the IOB-15-05B when the equipment is idle or lightly loaded?

A key advantage of this module is its low no-load power consumption of less than 0.25W. That helps reduce standby energy use in equipment that spends long periods powered but not actively drawing much load.

What certifications or safety characteristics does the IOB-15-05B offer?

Mean Well lists this model as Safety Class II and states compliance with IEC62368-1 under LVD approval. It also has 3KVac input-to-output withstand voltage and is backed by a 3-year warranty.
