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 PD-2512 for 12V industrial control and automation circuits?
Yes, it is a dual-output constant-voltage supply providing +12V and -12V, each rated 1A (1.2A max), with 24W total. That makes it appropriate for lower-power ±12V control, sensing, and automation loads that stay within its output rating.
Is the PD-2512 suitable for 12V embedded systems or small instrumentation equipment?
It is designed for constant-voltage ±12V applications with 24W total and 1A rated per channel. For embedded or instrumentation use, it is best matched to compact electronics needing +12V and/or -12V rather than loads that need more than 1A per rail.
Can the PD-2512 power 12V monitoring, alarm, or communications devices in a cabinet?
It can be used for ±12V cabinet-mounted electronics that require a regulated constant-voltage supply and fit within 24W total output. The 1A rating per channel is the main sizing limit for alarm, monitoring, and communications hardware.
Can the PD-2512 be used in outdoor or temperature-variable environments?
The operating temperature range is -10°C to +60°C, with output derating at higher temperatures per the derating curve. The specs do not list an IP rating, so they do not state outdoor or moisture-exposed suitability.
What are the main differences between the PD-2512 and other PD series units listed here?
PD-2512 is 24W with +12V/-12V at 1A each. The other PD-25 series models are PD-2505 at 25W 5V/-5V 2.5A each, PD-2515 at 24W 15V/-15V 0.8A each, PD-25A at 24.9W 5V 2.1A/12V 1.2A, and PD-25B at 25.2W 5V 1.2A/24V 0.8A.
