Test conditions and notes5
  1. 1. All parameters NOT specially mentioned are measured at 230VAC 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 0.1uf & 47uf parallel capacitor.
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. 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.” (as available on http://www.meanwell.com)
  5. 5. Derating may be needed under low input voltages. Please check the derating curve for more details.

FAQ

Can I use the SP-75-48 for lower-power 48V telecom or network equipment?

Yes, this model provides a constant voltage 48V output rated for 76.8W and 1.6A. It is suited to 48V equipment that stays within that current and power envelope.

Is the SP-75-48 suitable for 48V industrial control or communication devices?

It can support 48V DC devices that need a fixed 48V supply and draw no more than 1.6A. The relatively low current rating makes it a better fit for lighter 48V loads rather than high-power 48V systems.

Can this power supply run a 48V embedded or monitoring subsystem?

Yes, if the subsystem is designed for 48V constant voltage and total demand remains at or below 76.8W. The 85-264VAC input also helps when the AC source varies across facilities.

Is the SP-75-48 rated for outdoor installations?

The operating temperature range is -10°C to +60°C. No IP rating is shown in the provided specs, so outdoor weather exposure is not confirmed from this data.

When is the SP-75-48 the right size for a 48V application?

It is the right size when the 48V load stays within 1.6A and 76.8W total. For 48V systems above 1.6A, a higher-capacity 48V model would be the better choice.
