Test conditions and notes7
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
- 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. Tolerance : includes set up tolerance, line regulation and load regulation.
- 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. Mounting holes M1 and M2 should be grounded for EMI purposes.
- 6. Heat Sink HS1,HS2 can not be shorted.
- 7. Touch current was measured from primary input to DC output.

FAQ
Can I use the MPD-45A for small 5V industrial control or embedded loads?
Yes, if the load requires constant 5V and stays within the 5V channel's 3.2A rating and the unit's 40W total. Its second 12V channel (2A) can also supply 12V circuits within that total.
Is the MPD-45A suitable for 5V sensors, interface boards, or compact automation electronics?
It can be a fit where the 5V demand does not exceed 3.2A and the combined load of both channels stays within 40W. The constant-voltage output is intended for electronics that need a stable 5V rail.
Would the MPD-45A work for bench or cabinet use with smaller 5V test and monitoring devices?
Yes, for low-to-moderate 5V loads that stay within its 40W rating and 3.2A output current. Its 127.0 x 76.0 x 28.0 mm size and 0.2 kg weight also make it easier to place in smaller equipment spaces.
How does the MPD-45A differ from other listed MPD models in output capacity?
MPD-45A is the lower-power model of the MPD-45 series at 40W, with 5V at 3.2A and 12V at 2A. Its sibling MPD-45B is rated 44.8W, with 5V at 3.2A and 24V at 1.2A.
Is the MPD-45A suitable for outdoor or wide-temperature use?
Its operating temperature is specified at -10°C to +60°C, so it is intended for controlled equipment environments rather than extreme exposure. The provided specs do not include an IP rating, so outdoor use or unprotected moisture exposure should not be assumed.
