Test conditions and notes4
- 1. All parameters NOT specially mentioned are measured at 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 MHB150-48S05 to power 5V industrial controllers from a nominal 48V DC bus?
This model is designed for systems with a 36-75V input range and provides a constant 5V output. It can supply up to 30A with a 150W power rating, which fits 5V control electronics that need regulated low-voltage output from a 48V-class source.
Is this DC-DC converter suitable for 5V embedded computing or edge devices in automation cabinets?
It is a fit for embedded or industrial computing loads that require constant 5V power within a 150W budget. The unit delivers up to 30A at 5V and uses a compact 61.0 × 57.9 × 12.7 mm form factor for space-constrained equipment.
Can this converter support 5V I/O modules or sensor hubs in a wide-temperature industrial system?
The operating case temperature range is -40°C to +100°C, with thermal shutdown at 100°C ±5°C case temperature, so proper derating or cooling is needed. Electrically, it provides constant 5V output up to 30A and accepts 36-75V input.
Is the MHB150-48S05 appropriate for telecom or embedded platforms built around a 36-75V power architecture?
Yes, its stated input range is 36-75V, so it aligns with equipment that distributes power in that range and needs a constant 5V rail. The converter is rated for 150W and 30A output, which suits higher-current 5V subsystems.
Can I use this converter outdoors or in exposed environments?
The listed specs confirm an operating case temperature range of -40°C to +100°C, but no IP rating is provided. That means the temperature range is defined, while weather or water exposure suitability is not specified in the provided data.
