Test conditions and notes5

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. Direct connecting to LEDs is suggested, but is not suitable for using additional drivers.
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. 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. 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 PCD-25-350B power a string of signage LEDs?

Yes, when the signage load is designed for constant current at 350mA and the total forward voltage stays within 40-58V. Because the unit is constant current, it is not the right choice for constant voltage LED systems.

Is this driver suitable for a narrow LED downlight array?

It can be, provided the downlight uses a 350mA constant current driver and the LED load operates in the 40-58V range. The available output power is 20.3W, so the fixture also needs to remain within that limit.

Can I use the PCD-25-350B with a compact custom LED array?

Yes, if the array is built around 350mA constant current operation and its combined forward voltage is between 40V and 58V. That makes it suitable for higher-voltage, lower-current LED arrays within the 20.3W rating.

What makes an LED load compatible with the PCD-25-350B?

The load must require 350mA constant current and fall within the 40-58V constant current output range. The number of LEDs depends on each LED's forward voltage, so you should size the string by current and total forward voltage instead of by a fixed count.

How does the PCD-25-350B compare with the other PCD-25 models?

Within the PCD-25 range, the 350mA versions are 40-58V at 20.3W, the 700mA versions are 24-36V at 25.2W, the 1050mA versions are 16-24V at 25.2W, and the 1400mA versions are 12-18V at 25.2W. The PCD-25-350B is the 350mA, 40-58V model with 180-295VAC input.
