  1. 1. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
  2. 2. Direct connecting to LEDs is suggested, but is not suitable for using additional drivers.
  3. 3. 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.
  4. 4. 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).
  5. 5. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf

FAQ

Can I use the PLD-25-1050 for a 1050mA LED downlight?

Yes, if the downlight is built for 1050mA constant current and the LED load operates within the 16-24V constant current range. This model provides up to 25.2W of output power. It is meant for constant current LED loads, not constant voltage fixtures.

Is the PLD-25-1050 suitable for brighter small LED arrays?

Yes, it can support small LED arrays that require 1050mA constant current and have a total forward voltage between 16V and 24V. The exact LED count depends on the forward voltage of each LED. Its 25.2W rating sets the maximum load for the array.

Can this model be used for compact signage modules that need constant current?

It can be used for signage modules only if they are designed for 1050mA constant current operation and fall within the 16-24V CC range. If the signage system expects constant voltage, this driver is not appropriate. The output mode here is constant current only.

How do I check LED compatibility with the PLD-25-1050?

Look for an LED load that requires 1050mA constant current and whose operating range fits inside 16-24V on the output. The number of LEDs depends on each LED's forward voltage, so there is no single fixed LED quantity. The load should also stay within the 25.2W power rating.

What conditions is the PLD-25-1050 designed to handle?

This driver is rated IP42, so it is intended for protected environments rather than direct exposure to rain or washdown. Its operating temperature range is -30°C to +60°C. Output must be derated at the higher end of that range according to the sheet's derating curve.
