Test conditions and notes7
  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 0.1μF & 47μF 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 https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
  5. 5. Mounting holes M1 and M2 should be grounded for EMI purposes.
  6. 6. Heat Sink HS1,HS2 can not be shorted.
  7. 7. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ

Can I use the PD-45A for a 5V industrial controller or larger interface assembly?

Yes, this model is suitable for 5V constant voltage industrial electronics. It delivers 5V at 3.2A rated on CH1 plus a second 12V output at 2A on CH2, with 40W total rated output power.

Is the PD-45A appropriate for embedded systems with multiple 5V boards or peripherals?

It can be a good fit when the combined 5V load stays within 3.2A. The 12V CH2 output (2A) can also supply peripherals, as long as the total stays within the 40W rating.

Can the PD-45A power 5V automation displays, logic modules, or monitoring equipment?

Yes, it is designed for constant voltage applications and can be used for 5V automation displays, logic modules, or monitoring electronics up to 3.2A. Its 12V CH2 output at 2A can power related 12V devices in the same equipment.

Is the PD-45A suitable for outdoor cabinets or damp locations?

The operating temperature range is -10°C to +60°C, but no IP rating is provided in the listed specs. That points to indoor or otherwise protected use rather than exposed outdoor or wet environments.

What size 5V load is the PD-45A meant to support compared with smaller 5V PD units?

The PD-45A provides 5V at 3.2A rated on CH1 and 12V at 2A on CH2, for 40W rated output power with convection cooling, or up to 52W with 18CFM minimum forced air.
