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-15-24A designed for?

The IOB-15-24A is a 15W AC-DC on-board power module intended for OEM and embedded equipment that needs a regulated 24V DC output. Its edge connector format and compact body make it suitable for space-constrained industrial or commercial system designs.

What output does the IOB-15-24A provide?

This model provides a single 24V DC output rated at 0.625A, with a total power rating of 15W. It is intended for applications that need a compact low-power AC-DC conversion stage rather than a higher-current external power supply.

What input range does the IOB-15-24A support?

The IOB-15-24A accepts a wide 85 to 305Vac input range and also supports 100 to 430Vdc input. That broad range is useful for equipment that may be deployed across regions or in systems with varying available input power conditions.

Can the IOB-15-24A be used in demanding temperature environments?

Yes, this module is specified for operation from -40C to +85C, subject to the product's derating guidance. That makes it a practical choice for many industrial and enclosed equipment environments where ambient temperatures can vary widely.

What protection features are included in the IOB-15-24A?

The IOB-15-24A includes short circuit, overload, and over-voltage protection. Short circuit and overload protection use automatic recovery behavior, which helps protect the power module and downstream equipment during fault conditions.

How compact is the IOB-15-24A compared with larger enclosed power supplies?

The IOB-15-24A measures 44.5 x 25 x 15 mm and weighs about 0.0112 kg, making it much smaller and lighter than typical enclosed chassis-mounted power supplies. It is better suited to applications where board-level integration and space savings matter more than higher output power.
