Test conditions and notes11
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. Derating may be needed under low input voltage. Please check the static characteristics for more details.
  5. 5. Please refer to "DRIVING METHODS OF LED MODULE".
  6. 6. Heat sink HS1,HS2 can not be shorted.
  7. 7. Heat sink HS1 must have safety isolation distance with system case.
  8. 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. 9. Direct connecting to LEDs is suggested, but is not suitable for using additional drivers.
  10. 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. 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.
