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 MHB150-48S24 to power 24V industrial sensors or actuators from a 48V DC bus?
This model accepts 36-75V input and provides a constant 24V output, so it fits 48V-class systems that need a regulated 24V rail. It is rated for 150W and can supply up to 6.25A at 24V.
Is this converter appropriate for 24V automation equipment in embedded or industrial control systems?
It is suited to 24V loads that need constant-voltage output and stay within 150W total power. The available output current is 6.25A, and the unit is compact at 61.0 × 57.9 × 12.7 mm.
Can the MHB150-48S24 be used in wide-temperature factory or mobile equipment?
The specified 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. The electrical rating is constant 24V output at up to 6.25A from a 36-75V input.
Would this work for 24V monitoring, interface, or control subsystems on a 36-75V power architecture?
Yes, the stated input range is 36-75V and the output is regulated at 24V constant voltage. The converter provides up to 6.25A with a 150W power rating for 24V subsystem loads.
Can I install this converter in an exposed outdoor enclosure?
The specs provide an operating case temperature range of -40°C to +100°C, but no IP rating is listed. That means thermal capability is specified, while outdoor exposure resistance is not defined in the provided data.
