Frequently Asked Questions

Can I use the LPF-40D-42 for a 42V constant-current LED sign module?

Yes, if the sign module is designed for constant-current operation within the 25-42V range and needs up to 0.96A. This driver provides 40.32W at 42V with built-in 3 in 1 dimming, so it fits dimmable 42V LED lighting loads within those limits.

Is this driver suitable for outdoor architectural lighting at 42V?

It can be used for outdoor architectural LED fixtures if the fixture is rated for 42V constant-current operation and no more than 40.32W. The IP67 waterproof rating and -40°C to +80°C operating temperature support wet and exposed environments.

Can the LPF-40D-42 run dimmable LED lighting for display or signage projects?

Yes, it is intended for dimmable constant-current LED loads and includes built-in 3 in 1 dimming. The output is 42V at 0.96A, so the lighting load needs to fall within the 25-42V constant-current range and stay under 40.32W.

How much 42V LED strip or linear lighting can this driver support?

The maximum load is 40.32W. To estimate supported length, divide 40.32W by your strip or linear light's rated watts per meter; for example, the formula is 40.32W ÷ watts per meter = maximum length, and you should check your strip rated power per meter.

What is the difference between the LPF-40D-42 and the other LPF-40D models?

Within the LPF-40D series, the dimmable 40W models are 12V 40.08W 3.34A, 15V 40.08W 2.67A, 20V 40W 2A, 24V 40.08W 1.67A, 30V 40.2W 1.34A, 36V 40.32W 1.12A, 42V 40.32W 0.96A, 48V 40.32W 0.84A, and 54V 41.04W 0.76A. The LPF-40D-42 version is the 42V option in that group.
