FAQ – Frequently Asked Questions
Why do I need to account for a 20% power reserve with 12V power supplies?
12V systems operate with higher current loads than 24V variants. If you continuously load a power supply to 100% of its capacity, it leads to overheating, transformer whining, and a drastic reduction in lifespan. By keeping a 20% reserve (e.g., choosing a 100W power supply for an 80W load), you ensure the power supply runs in an optimal and cool operating mode.
What is the difference between a perforated (indoor) and potted (waterproof) 12V power supply?
Perforated metal-cased power supplies feature excellent natural ventilation, but they are intended exclusively for dry, dust-free spaces (such as drop ceilings or switchboards). Potted waterproof power supplies (often in an IP67 rating) are completely encased in resin, meaning moisture and dust cannot harm them, making them ideal for outdoor signs, bathrooms, or weather-exposed light boxes.
Can I place a 12V power supply in a completely enclosed space without ventilation?
It is possible, but you must be very careful. Every 12V power supply generates heat during operation. If you lock it inside a hermetically sealed small box or furniture body without air circulation, heat accumulates, which can trigger thermal protection or lead to premature failure. In such cases, it is better to choose a power supply with a lighter load or ensure at least minimal ventilation.
How long can the cable be between the 12V power supply and the LED strip?
In 12V wiring, cable length plays a massive role due to voltage drop. The longer and thinner the cable you use, the more voltage is "lost" along the way, causing the LED strip at the end to shine dimmer. For longer runs, we recommend using thicker wire gauges (e.g., 1.5 mm² or 2.5 mm²) or powering longer lines from both ends.
