Test conditions and notes6
- 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 0.1μF & 47μF 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 https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
- 5. Heat Sink HS1,HS2 & HS3 can not be shorted.
- 6. 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 PPT-125D for industrial equipment that needs multiple regulated DC outputs from one supply?
Yes, this model is a triple output supply (5V, 24V and 12V) with PFC, rated 101W in free-air convection and 125W with 18CFM forced-air cooling. That makes it suitable for industrial, embedded, or automation systems that need several regulated DC rails from one compact supply.
Is the PPT-125D a good choice for control systems that run from wide AC input ranges?
Yes, it has a universal AC input of 90-264VAC (47-63Hz), and the input range is also listed as 127-370VDC. That supports use in equipment deployed across a broad AC supply range, with output power of 101W in convection or 125W with 18CFM forced air.
Can this power supply support a 5V load rail in a larger embedded or automation assembly?
Yes, CH1 is 5V rated at 7A in convection (up to 8.75A with 18CFM forced air), adjustable from 4.75 to 5.25V. In a multi-rail system, that 5V output can support embedded logic, control electronics, or peripherals while the 24V and 12V channels supply additional regulated rails within the unit's total rated power.
Is the PPT-125D suitable for space-constrained equipment builds?
It is designed in a 127.0 × 76.2 × 34.6 mm package and is described as a 5" x 3" compact size. For systems that need up to 125W (with 18CFM forced air) and triple output in a relatively compact enclosure footprint, those dimensions are a relevant fit consideration.
How does the PPT-125D compare with the other PPT-125 series models?
The models differ in output voltages: PPT-125A is 3.3V/5V/12V, PPT-125B 5V/12V/-12V, PPT-125C 5V/15V/-15V and PPT-125D 5V/24V/12V. Rated power with 18CFM forced air is 98.81W (A), 124.46W (B), 125.15W (C) and 126.43W (D), so PPT-125D has the highest rating, narrowly ahead of the B and C models.
Can the PPT-125D be used in demanding temperature conditions indoors?
The specified operating temperature range is -20°C to +70°C, with output derating at higher temperatures per the derating curve. No IP rating is provided in the specs and the unit is intended as a component installed in final equipment, so the data supports temperature suitability but does not confirm outdoor or water-exposed use.
