Frequently Asked Questions
Can I use the LPF-90-20 for 20V LED strip lighting?
Yes, if the strip or lighting load is designed for 20V operation and the total demand stays within 90W and 4.5A. This model provides 20V output and is suited to 20V lighting loads that need more capacity than lower-wattage 20V units.
Is the LPF-90-20 suitable for 20V LED signage or lightbox applications?
It can be, as long as the sign or lighting load is a 20V load and does not exceed 90W or 4.5A. The wide 90-305VAC input also makes it practical for projects that need a broad AC input range.
Can this driver be used in outdoor or wet 20V lighting environments?
Yes, the IP67 waterproof rating supports outdoor and wet-location use. The operating temperature range is -40°C to +70°C, so the unit is built for harsher environmental conditions than an indoor-only supply.
How do I estimate LED strip length for the LPF-90-20?
Use the maximum output power of 90W and divide it by the strip wattage per meter. The sizing math is 90W / W per meter, but you need to check your strip rated power per meter and confirm it is a 20V strip.
How does LPF-90-20 compare with the other LPF-90 models?
In the non-dimming LPF-90 range, the models are LPF-90-15 at 75W, 15V, 5A; LPF-90-20 at 90W, 20V, 4.5A; LPF-90-24 at 90W, 24V, 3.75A; LPF-90-30 at 90W, 30V, 3A; LPF-90-36 at 90W, 36V, 2.5A; LPF-90-42 at 90.3W, 42V, 2.15A; LPF-90-48 at 90.24W, 48V, 1.88A; and LPF-90-54 at 90.18W, 54V, 1.67A. The dimming versions are LPF-90D-15 at 75W, 15V, 5A; LPF-90D-20 at 90W, 20V, 4.5A; LPF-90D-24 at 90W, 24V, 3.75A; LPF-90D-30 at 90W, 30V, 3A; LPF-90D-36 at 90W, 36V, 2.5A; LPF-90D-42 at 90.3W, 42V, 2.15A; LPF-90D-48 at 90.24W, 48V, 1.88A; and LPF-90D-54 at 90.18W, 54V, 1.67A.
