Test conditions and notes4
- 1. All parameters NOT specially mentioned are measured at 12,24,48VDC 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 MHB75-24S24 for 24V industrial automation devices?
Yes, it is intended for 24V constant-voltage loads up to 3.13A and 75W. That makes it suitable for industrial automation devices, control electronics, or embedded systems that require a regulated 24V DC output from an 18-36VDC input range.
Is this converter appropriate for 24V monitoring or control modules in compact equipment?
It can fit compact equipment because the housing measures 61.0 × 57.9 × 12.7 mm and weighs 95 g. Electrically, it provides a 24V constant-voltage output with up to 3.13A available.
Can the MHB75-24S24 be used in equipment exposed to very hot or very cold operating conditions?
The specified operating range is -40°C to +100°C case temperature, with thermal shutdown at 100°C ±5°C. For 24V loads within 75W and 3.13A in hot or cold environments, apply derating or cooling (airflow or the optional heat sink) per the thermal curve.
Is the MHB75-24S24 rated for outdoor installation?
The specs give an operating range of -40°C to +100°C case temperature, with thermal shutdown at 100°C ±5°C, but they do not include an IP rating. Without an IP rating in the published data, outdoor exposure or wet-location suitability cannot be confirmed here.
What separates the MHB75-24S24 from the other models in this family?
This version uses an 18-36VDC input range and provides 24V at 3.13A, all within the common 75W family rating. The sibling models cover the same 75W platform in three output levels, 5V 15A, 12V 6.25A, and 24V 3.13A, repeated across 9-18VDC, 18-36VDC, and 36-75VDC input groups.
