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. Derating may be needed under low input voltages. Please check the derating curve for more details.
- 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 SPV-300-12 for 12V industrial LED lighting or signage?
Yes, this model is a constant-voltage 12V supply rated for 300W and 25A, which fits higher-load 12V lighting systems. It is a better fit for applications that need a regulated 12V output rather than a constant-current driver.
Is the SPV-300-12 suitable for a 12V CCTV or security system with multiple devices?
It can be used where the overall system requires a constant 12V source and the total load stays within 300W and 25A. That makes it relevant for larger 12V security or monitoring systems that are centralized around one power supply.
Can this power supply run 12V embedded or automation equipment in a control cabinet?
Yes, the 12V constant-voltage output and 25A capacity make it suitable for 12V industrial, embedded, or automation loads that draw from a shared DC bus. The wide 88-264VAC input is also useful in equipment that may be deployed across different AC input environments.
Is the SPV-300-12 a good choice for 12V motors, fans, or relays in industrial equipment?
It is appropriate for 12V DC loads when the combined demand remains within 300W and 25A. Buyers typically use this type of constant-voltage supply for 12V auxiliaries such as fans, relays, and similar control-side loads.
Is the SPV-300-12 suitable for outdoor or harsh-environment use?
The listed operating temperature is -20°C to +65°C. The unit uses forced air cooling by a built-in DC fan, so it requires adequate ventilation and is not suitable for sealed outdoor or washdown environments without additional protection.
