Frequently Asked Questions
Can I use the LPF-40-12 for 12V LED strip lighting?
Yes, it can be used for 12V LED strip lighting as long as the total strip load stays within 40.08W. It provides 12V output at up to 3.34A, so the strip voltage must match 12V and the total wattage must not exceed the driver rating.
Is the LPF-40-12 suitable for 12V LED sign modules?
It is suitable for 12V LED sign modules when the full sign load is 40.08W or less. The 12V output matches 12V signage products, and the IP67 housing makes it a fit for signs exposed to weather.
Can this driver power outdoor 12V accent or landscape lighting?
It can be used for outdoor 12V lighting loads that stay within 40.08W. The unit is rated IP67 Waterproof and operates from -40°C to +80°C, which supports use in wet and demanding outdoor conditions.
How much 12V LED strip can the LPF-40-12 run?
Maximum strip length depends on the strip's watts per meter. The math is 40.08W divided by your strip's rated W/m, and you should also confirm the strip is a 12V product and keep the total load at or below 40.08W.
Is the LPF-40-12 okay for wet locations or outdoor signage?
Yes, the IP67 Waterproof rating means it is intended for wet and outdoor environments. Its operating temperature range is -40°C to +80°C, so it is suited to both cold and hot conditions when the rest of the system is rated the same way.
How does the LPF-40-12 compare with other LPF-40 models?
Within the LPF-40 series, the fixed-output models are LPF-40-12 at 40.08W, 12V, 3.34A; LPF-40-15 at 40.08W, 15V, 2.67A; LPF-40-20 at 40W, 20V, 2A; LPF-40-24 at 40.08W, 24V, 1.67A; LPF-40-30 at 40.2W, 30V, 1.34A; LPF-40-36 at 40.32W, 36V, 1.12A; LPF-40-42 at 40.32W, 42V, 0.96A; LPF-40-48 at 40.32W, 48V, 0.84A; and LPF-40-54 at 41.04W, 54V, 0.76A. The main selection difference is matching the output voltage and current rating to the load.
