Affect life span of the power switch times: Most power has capacitor input type rectifier circuit, when the electric power was turned Tianshui LED waterproof power suppliers, will produce surge current causes the switch contacts to fatigue, caused by contact resistance increases and adsorption and other issues. Theorized that life expectancy during power, the number of switch-off about 10,000 times. Supply voltage Protection class standard lightning impulse breakdown voltage peaks at rated discharge current Isn Tianshui LED waterproof power outlets, the residual voltage of the protected side, in terms of the power system arrester according to overvoltage category (1,2,3 Tianshui LED waterproof power supply professional production, 4), to determine their level of protection installed; for information system protection, the protection level must match the desire to protect systems and equipment compatibility. Tianshui LED waterproof power supply manufacturers, Shenzhen far lighting (certified), LED waterproof power supply away from the Shenzhen Lighting Limited. Lighting Co., Ltd.
