Test conditions and notes4
  1. 1. All parameters NOT specially mentioned are measured at 12,24,48VDC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. The power supply need to connect "+Vout" to "+R.S" and "-Vout" to "-R.S".
  4. 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 MHB75-24S05 for 5V industrial logic or controller loads?

It is intended for constant-voltage 5V loads and can supply up to 15A with a 75W power rating. That makes it appropriate for industrial logic, controller, or embedded electronics that are built around a 5V DC bus and have an 18-36VDC input source available.

Is this model suitable for powering 5V embedded electronics from a higher-voltage input range?

Yes, this unit is designed for an 18-36VDC input range and converts that to a 5V constant-voltage output. With up to 15A available, it fits 5V embedded systems that need more current than the 12V or 24V output variants provide.

Can the MHB75-24S05 support 5V automation or communication hardware that draws higher current?

For 5V equipment, this is the highest-current option in the listed 24V-input siblings because it delivers up to 15A at 75W. That makes it a practical choice for 5V automation or communication hardware where current demand matters more than a higher output voltage.

Is the MHB75-24S05 appropriate for harsh indoor environments with temperature extremes?

The operating range is -40°C to +100°C case temperature, with thermal shutdown at 100°C ±5°C, and derating or cooling is needed per the thermal curve. The specs do not provide an IP rating, so the temperature range is clear but indoor or outdoor exposure resistance is not defined here.

What is the difference between the MHB75-24S05 and the other 18-36VDC input versions?

Within the 18-36VDC input group, the MHB75-24S05 outputs 5V at 15A, the MHB75-24S12 outputs 12V at 6.25A, and the MHB75-24S24 outputs 24V at 3.13A. All three are 75W models with the same 61.0 × 57.9 × 12.7 mm dimensions, 95 g weight, and -40°C to +100°C operating case temperature range.
