  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 the PLD-40-1050B be used for a 1050mA LED downlight?

Yes, this driver is built for constant current LED loads at 1050mA. It fits downlights whose total forward voltage is within the 22-38V CC range and whose load remains within the 39.9W rating.

Is the PLD-40-1050B suitable for higher-power small LED arrays?

It can be a fit for small LED arrays that need 1050mA constant current rather than constant voltage input. The array's combined forward voltage must stay between 22V and 38V, with total power up to 39.9W.

Can this driver be used in signage with constant current LED modules?

Yes, if the signage modules are designed for constant current operation at 1050mA. It should not be used in place of a constant voltage supply, and the load must stay within the 22-38V CC window.

Is the PLD-40-1050B appropriate for protected indoor environments?

Its IP42 rating makes it better suited for protected indoor locations than exposed outdoor use. The rated operating temperature is -30°C to +50°C (see the derating curve), which supports a broad range of indoor commercial and industrial fixture conditions.

How do I check compatibility with the PLD-40-1050B?

This model provides 1050mA constant current with a CC output range of 22-38V. The number of LEDs depends on each LED's forward voltage, so compatibility depends on the total forward voltage of the LED load, not a fixed LED count.

How does the PLD-40-1050B compare with other 40W PLD drivers?

The PLD-40-1050B delivers 1050mA with a 22-38V CC range and 39.9W output. Other 40W siblings include PLD-40-1400B at 1400mA, 17-29V, 40.6W; PLD-40-1750B at 1750mA, 13-23V, 40.25W; PLD-40-700B at 700mA, 34-57V, 39.9W; PLD-40-500B at 500mA, 45-80V, 40W; and PLD-40-350B at 350mA, 70-108V, 37.8W.
