After being tested by this department, the product can still bear 50Hz under the conditions of the boom. The insulation intensity requirement is 1500W test voltage breakdown for 1 minute. The circuit board will be protected by three -proof paint. The quality of large LEDs and large screens should be higher than IP65 waterproof in the international protection system.class. In this way, it can ensure leakage from material to waterproof performance
