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-05-24 designed for?

The IOB-05-24 is a compact AC-DC on-board power module intended for space-constrained equipment that needs a regulated 24V output. It is suited to embedded and OEM designs where a small form factor and direct PCB-mounted power solution are important.

What are the key output specifications of the IOB-05-24?

This model provides a 24V DC output with a rated current of 0.21A and a 5.04W power rating. Ripple and noise are specified at 150mV, and the unit includes short circuit, overload, and over voltage protection.

What input range does the IOB-05-24 support?

The IOB-05-24 accepts a wide 85 to 305Vac input range and also supports 100 to 430Vdc input. That wide range makes it suitable for designs that need flexibility across varying global power conditions.

Can the IOB-05-24 be used in demanding temperature conditions?

Yes. This module is rated for operation from -40°C to +85°C, which makes it suitable for equipment exposed to wide ambient temperature variation. It is cooled by free air convection and is specified for industrial-style operating environments.

What makes the IOB-05-24 different from larger enclosed power supplies?

The IOB-05-24 is built as an on-board power module with a very compact 26.4 x 14.73 x 11mm size, rather than as a larger enclosed supply. It is intended for systems where board space, low no-load power consumption, and compact integration are more important than a larger standalone power form factor.

What compliance and reliability details are provided for this model?

The IOB-05-24 is approved to IEC62368-1 under LVD and is listed as Safety Class II. Its typical MTBF is over 10,000K hours (MIL-HDBK-217F, 25°C), which is useful for OEM and B2B buyers evaluating long-term reliability.
