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 MHB100-48S05 to power 5V industrial logic from a 36-75VAC source?
Yes, this model is designed for 36-75VAC input and provides constant 5V output. Its 20A output current and 100W power rating make it appropriate for high-current 5V logic, controllers, and embedded electronics within those limits.
Is this converter suitable for 5V embedded processors or industrial communication hardware?
It can be a fit for 5V embedded and communications hardware when the total load stays at or below 20A and 100W. The constant-voltage 5V output is intended for electronics that require a fixed 5V rail rather than a higher 12V or 24V bus.
Can the MHB100-48S05 support multiple 5V automation boards in one system?
It is suited to grouped 5V loads as long as the combined demand does not exceed 20A or 100W. That makes it useful for dense low-voltage control assemblies powered from a 36-75VAC input range.
Is the MHB100-48S05 appropriate for outdoor cabinets or temperature-extreme installations?
The operating temperature range is -55°C to +105°C, so the temperature spec supports very cold and very hot environments. However, no IP rating is listed in the provided specs, so the information here does not verify exposed outdoor or wet-location use.
How does the MHB100-48S05 compare with the other models in the series?
All listed MHB100 siblings are rated at 100W. The available outputs are 5V 20A, 12V 8.3A, and 24V 4.17A, offered across both the 24S input family and the 48S input family, including this 48S05 model.
