Issue #1: I purchased a 60W led power supplies (aka. LED driver). Why do the instructions indicate that I’m just able to draw 30W from the IT on a hot Summer’s day?
An LED driver is Usually rated under specific test conditions. It’s a regular industry practice to accelerate the output level in 25 degrees C ambient temperatures. However, an outside LED signage is usually confronting a higher ambient temperatures onto a hot Summer’s day. In this scenario, the output needs to be restricted so that the energy source itself can operate under a stressful condition and creates less heat. It’s urged to adhere to this output de-rating curve offered by the producer to find out the highest allowable drawing gift in real world conditions.
Issue #2: My LED electricity source will be exposed to the atmosphere. Can I need to put it in an extra watertight enclosure?
If the LED driver used is not design with authentic watertight attribute, an enclosure is unquestionably needed. The moisture in the air will eventually corrode the position, get from the circuit board, brief the circuitry, and create a hazard. You will find true waterproof supplies readily available on the market. It’s normally equipped with a completely sealed case with water and rust resistance paint on the exterior. Additionally, there are water-tight connectors as well as the conduit used on the input / output to be sure the moisture can’t flow in the position on the port. Start Searching to your UL1310-Wet or the UL50 certificate from the maker. It is the certification UL (Universal Laboratory) grants to the producer if their product passes the moist location usage evaluation.
