Test conditions and notes4
- 1. All parameters NOT specially mentioned are measured at 24,48VDC 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 1uf ceramic & 10uf tantalum capacitor across output.
- 3. The power supply need to connect "+Vout" to "+R.S" and "-Vout" to "-R.S".
- 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to "EMI testing of component power supplies."

FAQ
Can I use the MHB100-24S24 for 24V industrial control equipment on an 18-36VDC source?
Yes, this converter accepts 18-36VDC input and delivers a regulated 24V output. With 100W total power and 4.17A output current, it fits 24V control loads that stay within those ratings.
Is this a good fit for 24V PLC I/O modules or automation interfaces?
It is suitable for 24V automation electronics that require constant voltage and draw no more than 4.17A or 100W. The 24V output matches many industrial control and interface loads better than the 5V or 12V versions in the same series.
Can the MHB100-24S24 power 24V embedded or communications devices inside industrial systems?
Yes, when the device expects a steady 24V supply and its load remains within 4.17A and 100W. Its 61.0 x 57.9 x 12.7 mm form factor and 0.095 kg weight also support compact equipment layouts.
Will this converter handle cold or high-heat environments?
The specified operating range is -40°C to +100°C case temperature, with thermal shutdown at 100°C±5°C, so derating or added cooling is needed per the thermal curve. No IP rating is listed in the provided specs, so direct outdoor exposure is not confirmed here.
What is the difference between the MHB100-24S24 and the other listed MHB100 siblings?
All listed siblings are 100W models, but they differ by input family and output level. The 24S family includes 5V 20A, 12V 8.3A, and 24V 4.17A versions, and the 48S family includes 5V 20A, 12V 8.3A, and 24V 4.17A versions.
