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 are the main output specifications of the Mean Well IOB-05-15?

The IOB-05-15 is a compact on-board power module rated for 5.1W output. It provides a single 15V DC output with a rated current of 0.34A. This makes it suitable for low-power designs that need a regulated 15V rail in a very small footprint.

What kind of application is the IOB-05-15 best suited for?

This model is designed for systems where the power module is assembled on the main PCB and space is limited. Its 1 x 0.6 inch class size and 5.1W output make it a practical choice for compact embedded or control equipment that only needs modest 15V power. It is better suited to low-power board-level designs than to larger external power supply roles.

What input range does the Mean Well IOB-05-15 support?

The module accepts a wide input range of 85 to 305Vac, and it also supports 100 to 430Vdc input. That wide range helps it fit projects that may see different mains conditions without needing a different model.

Can the IOB-05-15 operate in demanding temperature conditions?

Yes, the specified operating temperature range is -40 to +85 degrees C, which is broad for a compact power module. That gives it more flexibility for equipment exposed to cold starts or elevated internal temperatures. Final suitability still depends on the thermal conditions of the end product and the stated derating guidance.

What protection features are built into the IOB-05-15?

The IOB-05-15 includes short circuit, overload, and over voltage protection. Short circuit protection is continuous with automatic recovery in hiccup mode, and overload protection also recovers automatically after the fault is removed. These built-in protections help support reliability in low-power electronic systems.

How does the IOB-05-15 compare with a larger enclosed power supply?

The IOB-05-15 is intended for on-board use and focuses on compact size, low no-load power consumption, and low-power 15V output. Compared with a larger enclosed supply, it is much smaller and better suited to designs that integrate the power stage directly onto the system PCB. It is not the right choice if the application needs substantially more than 5.1W or a higher output current.
