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 type of product is the Mean Well PLP-45-48?
The Mean Well PLP-45-48 is a single output LED power supply rated for 45W. It provides a 48V output (constant current region 36 ~ 48V) and is a component meant to be installed into final LED lighting equipment, driving LEDs directly.
What are the main electrical ratings of the PLP-45-48?
This model is rated for 45.6W output power with a 48V output voltage and 0.95A rated current. It also supports a universal AC input range of 90 to 264VAC (127 to 370VDC), which helps it fit a wide range of commercial and industrial power environments.
Is the Mean Well PLP-45-48 dimmable?
The PLP-45-48 datasheet does not list any dimming function or dimming input. Its output current can only be set within 0.715 ~ 0.95A, so it is better suited to applications that need stable fixed-output power rather than lighting systems that need dimming control.
Can the output current be adjusted on this LED driver?
Yes, the output current level on the PLP-45-48 is adjustable. The listed current adjustment range is 0.715 to 0.95A, i.e. 75% to 100% of rated current, which can help when matching the driver to compatible LED load requirements.
Is the PLP-45-48 suitable for demanding temperature conditions?
This model is rated for operation from -30°C to 70°C, with output derating required at higher ambient temperatures according to the derating curve. That makes it a practical option for LED lighting projects exposed to a broad range of ambient temperatures, provided the load stays within the derated limits.
What protection features does the Mean Well PLP-45-48 include?
The PLP-45-48 includes short circuit (hiccup mode), over current (constant current limiting) and over voltage (57 ~ 63V, shut down, re-power on to recover) protection. These built-in protections support reliability in professional LED lighting applications.
