Test conditions and notes11
- 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. Derating may be needed under low input voltage. Please check the static characteristics for more details.
- 5. Please refer to "DRIVING METHODS OF LED MODULE".
- 6. Heat sink HS1,HS2 can not be shorted.
- 7. Heat sink HS1 must have safety isolation distance with system case.
- 8. The power supply is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
- 9. Direct connecting to LEDs is suggested, but is not suitable for using additional drivers.
- 10. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED power supply can only be used behind a switch without permanently connected to the mains.
- 11. 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)

FAQ
What are the main electrical ratings of the Mean Well PLP-45-12?
The PLP-45-12 is a 45W single-output LED driver with a 12V DC output (constant current region 9 ~ 12V) and a rated current of 3.8A. It accepts a universal AC input range of 90 to 264VAC, with a PFC function (PF≧0.9 at 75 ~ 100% load). This makes it a compact option for LED loads in that power class.
Is the PLP-45-12 dimmable?
The datasheet does not list any dimming function or dimming input for this model; the output current can only be set within 2.85 ~ 3.8A. Buyers who need dimming functionality should treat that as a separate requirement when comparing driver options.
What kinds of LED applications is the PLP-45-12 designed for?
The PLP-45-12 is a component LED power supply to be installed into final lighting equipment, and Mean Well suggests connecting it directly to the LEDs in constant current mode. Its 12V output and 45W power rating make it relevant for LED systems that match those electrical requirements.
What protection features does the Mean Well PLP-45-12 include?
This model includes short circuit, over current and over-voltage protection. Short circuit protection works in hiccup mode and over current by constant current limiting, both recovering automatically; over voltage (15 ~ 18V) shuts down the output until the unit is re-powered.
What operating temperature range is the PLP-45-12 rated for?
The specified operating temperature range is -30°C to 70°C, with output derating required at higher ambient temperatures according to the derating curve. Working humidity is 20 ~ 95% RH non-condensing, and the unit is meant to be installed inside final equipment.
Is the PLP-45-12 a good fit for a 12V LED system that draws up to 3.8A?
It is designed for a 12V output with a rated current of 3.8A, so it aligns with LED applications that require those electrical values. Buyers should confirm that the LED load operates within the driver's 9 ~ 12V constant current region and stays within its 45W rating. The sheet notes it should drive LEDs directly and is not suitable for powering additional drivers.
