ELECTRIC SIGNAGE Many companies are moving to new, high-efficiency fan-less power supplies, with some achieving over 88 percent effi- ciency. The power supply is typically the most common point of LED display fail- ure. In outdated LED displays, clogged or broken fans cause the supply to overheat and burn up. By removing the fans and increasing efficiency there is a reduction in overall heat from the supplies. The rest of the heat is then dissipated by the aluminum cabinet it is housed on, creat- ing a large heat sink in the rear where airflow quickly cools it.
