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 0.1uf & 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. Touch current was measured from primary input to DC output.
- 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 PM-20-5 for a 5V PLC accessory, controller, or embedded computing load?
Yes, this is a constant voltage 5V power supply rated for 4.4A and 22W. It fits 5V industrial controllers, embedded computing boards, and automation peripherals that require a regulated 5V source within that output range.
Is the PM-20-5 suitable for powering several 5V USB-class or logic-level devices inside one machine?
It can support multiple 5V devices as long as the combined load does not exceed 4.4A or 22W. That makes it suitable for grouped 5V logic hardware, interface modules, and embedded accessories using a shared constant voltage rail.
Can this model be used for 5V HMI, gateway, or communications hardware in an automation panel?
Yes, the regulated 5V output and 4.4A current rating make it suitable for 5V HMI electronics, communications hardware, and automation support devices that stay within 22W. The 85-264VAC input range also supports use across a wide AC input range.
Is the PM-20-5 intended for outdoor or harsh exposed environments?
The operating temperature range is -20°C to +60°C, which supports a broad range of indoor equipment conditions. No IP rating is listed in the provided specs, so the product data does not identify it as an outdoor or water-exposed power supply.
