REFERENCE 参数 5.1 Fog Output 雾化量 Value 数值 300 ml/h ± 10% by using Siansonic standard unit 用东方金荣专用装置测试雾化量为 300 ml/h ± 10% Test Environment 测试环境 The DC input for Siansonic standard drive circuit Input voltage : 48V -3-

4 Current : 0.47A 东方金荣标准驱动电路直流输入输入电压 :48V 电流 :0.47A Water temperature : 25±3 C 水温 :25±3 C 5.2 TRANSDUCER LIFE 换能器寿命 The life that is set to be the period of continuous time where the current level of fog production decreased to 50% relative to initial level. The expected service life depends on input power, water quality and water temperature. For example, the life expectancy can be increased by lowering input power rate. 换能器寿命是指在输入功率水温等条件不变的情况下, 换能器不间断工作, 其发雾量减小到初始值的 50% 时所用的时间寿命与输入功率水质和水温有关例如, 降低输入功率可能会使换能器寿命提高 Water temp. = 20~40 C, 当水温在 20~40 时,10000 小时 In case of water temp 50~60 C 当水温在 50~60 时,5000 小时 In case of water temp 60~90 C 当水温在 60~90 时,2000 小时 * All data are measured under the standard input rate of power in pure water. * 所有数据均在额定功率下纯水中测得 -4-
