Frequently Asked Questions

Can I use the LPF-40D-20 with a 20V LED strip for illuminated displays?

Yes, if the display lighting is a 20V load and the total demand stays within 40W and 2A. The built-in 3 in 1 dimming is useful for display applications that need brightness adjustment.

Is this a good choice for 20V signage lighting that needs dimming?

It is suitable for 20V signage lighting loads that stay within the driver's 40W output and 2A current limit. The 12-20V CC range and dimmable design make it appropriate for controlled 20V LED lighting applications.

Can the LPF-40D-20 power 20V linear lighting in a damp environment?

Yes, for 20V linear lighting products that do not exceed 40W total. Its IP67 waterproof rating supports use in damp or wet environments where a sealed driver is needed.

How do I estimate the maximum 20V LED strip length for this driver?

Use the power limit: 40W divided by your strip's rated watts per meter equals the estimated maximum length. Check your strip rated power per meter, and make sure the full load stays within 40W and 2A.

Can this driver be used outdoors?

The LPF-40D-20 has an IP67 waterproof rating, so it is designed for outdoor and wet-location use where that protection level is appropriate. It is also rated for -40°C to +80°C operation.
