Frequently Asked Questions

Can I use the PLD-40-350B for LED downlights?

Yes, if the downlight is designed for constant current operation at 350mA and the LED load falls within the 70-108V constant current range. This driver delivers up to 37.8W, so it is better suited to higher-forward-voltage downlight arrays than low-voltage constant voltage products.

Is the PLD-40-350B suitable for LED signage modules?

It can work for signage modules that are built as a constant current 350mA load and stay within the 70-108V CC output range. It is not a constant voltage driver, so it should not be matched to signage products that expect a fixed voltage output.

Can this driver power a small LED array with a long series string?

Yes, this model is a fit for small LED arrays that need 350mA constant current and have a combined forward voltage within 70-108V. The 108V maximum output makes it more appropriate for longer series LED loads than lower-voltage constant current drivers in the same family.

Is the PLD-40-350B a good replacement for a 350mA constant current driver in an indoor fixture?

It is a reasonable replacement when the original driver was also constant current at 350mA and the fixture's LED load operates in the 70-108V range. You also need to stay within the 37.8W rating and the physical size of 127.0 x 60.0 x 31.5 mm.

How do I know if my LED load is compatible with the PLD-40-350B?

Compatibility depends on matching the output current and the driver's constant current voltage window. This unit supplies 350mA over 70-108V, and the number of LEDs depends on each LED's forward voltage, so it should be used with constant current loads rather than constant voltage strips or modules.

Is the PLD-40-350B suitable for damp or dusty locations?

It has an IP42 plastic case and an operating temperature range of -30°C to +50°C, which fits indoor environments with limited dust and light moisture exposure. It is not intended for fully exposed outdoor conditions where a higher IP rating would normally be required.
