Test conditions and notes5
- 1.All parameters are specified at normal input(A:12Vdc, B:24Vdc, C:48Vdc), rated load, 25℃ 70% RH ambient.
- 2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μf & 47μf capacitor.
- 3.Line regulation is measured from low line to high line at rated load.
- 4.Load regulation is measured from 10% to 100% rated load.
- 5.The final equipment must be re-confirm that it still meet EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”(as available on http://www.meanwell.com)

FAQ
Can I use the SPB09C-24 for a 24V industrial control or relay interface load?
Yes, if the load requires constant 24V and the source feeding the converter is within 36-75VDC. This model is rated for 9W output and listed at 375mA output current, so the connected 24V load needs to fall within those specs.
Is this a good fit for compact 24V embedded automation electronics?
It can fit compact 24V embedded electronics that need constant voltage and modest power draw. The unit delivers 24V output, is rated for 9W, and measures 24 x 9.6 x 11.2 mm.
Can the SPB09C-24 be used for low-power 24V monitoring or signaling equipment?
This converter is intended for constant 24V output applications powered from 36-75VDC input. With a 9W rating, it is better matched to lower-power 24V monitoring, signaling, or interface loads than larger 24V devices.
Would the SPB09C-24 work where board area and weight are tightly constrained?
Its compact size of 24 x 9.6 x 11.2 mm and weight of 5g make it suitable for space-sensitive designs. Those mechanical traits pair with a constant 24V output and 9W power class.
Is the SPB09C-24 suitable for outdoor equipment cabinets?
The thermal specification is -40°C to +90°C, which supports operation across a wide temperature range. No IP rating is listed in the provided data, so outdoor suitability depends on using an enclosure appropriate for the environment.
