FAQ

Can I use the MDS15C-24 to power a 24V sensor or relay circuit from a 36-75V DC bus?

Yes, this model is a constant-voltage DC-DC converter with a 24V output and a 15W power rating. Its input range is 36-75V, so it fits systems that need regulated 24V from a higher-voltage DC source. It is best suited to lower-power 24V control, sensing, or relay loads that stay within the 15W rating.

Is the MDS15C-24 suitable for embedded industrial control electronics that need isolated 24V power?

It is sized for compact embedded and industrial electronics that need a 24V constant-voltage output rather than a large bulk power supply. The compact 50.8 × 25.4 × 12.0 mm package and 0.03 kg weight make it easier to use where board or enclosure space is limited. The main sizing limit is its 15W output capacity.

Can this converter be used in automation equipment with a wide DC input range?

Yes, the 36-75V input range is useful in automation or control equipment where the upstream DC bus can vary within that span. The unit provides a fixed 24V output in constant-voltage mode. That makes it a fit for low-power 24V subsystems instead of variable-output applications.

How does the MDS15C-24 compare with the other MDS15C models?

All MDS15C models in this group are rated at 15W. The MDS15C-05 outputs 5V at 3A, the MDS15C-12 outputs 12V at 1.25A, the MDS15C-15 outputs 15V at 1A, and the MDS15C-24 outputs 24V at 625mA. The selection difference here is the output voltage and rated output current, not the series power class.

Is the MDS15C-24 appropriate for outdoor or harsh-temperature use?

Its operating temperature range is -40°C to +90°C (load derating applies at higher ambient temperatures per the derating curve), so the temperature spec is broad for demanding environments. However, no IP rating is listed in the provided specs, so it should be treated as a converter for protected indoor housings or enclosed equipment rather than exposed outdoor use. Temperature capability and ingress protection are separate considerations.
