REFERENCE 参数 4.1 Fog Output 雾化量 Value 数值 200 ml/h ± 10% by using Siansonic standard unit 用东方金荣专用装置测试雾化量为 200 ml/h ± 10% Test Enviroment 测试环境 -3-

4 The DC input for Siansonic standard drive circuit Input voltage : 24V Current : 0.6A 东方金荣标准驱动电路直流输入输入电压 :24V 电流 :0.6A 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 70% 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 70% 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. -4-

5 * 所有数据均在额定功率下纯水中测得 6. Service Conditions 使用条件 5.1 Liquid type: drinking water 使用水质 : 饮用水 5.2 Water temperature : 0~90 C (recommendation: 0~50 C) 使用水温 :0~90 C ( 推荐水温为 0~50 C) 5.3 Water level: 25~35mm 使用水位 :25~35mm 5.4 Power: <15W 使用输入功率 :<15W 5.5 Storage temperature : -20 C~65 C 保存温度 :-20 C~65 C 7. Points for attention in use 使用注意事项 6.1 Provide a protective low water shut-off circuit. 提供保护线路以避免无水状态使用 7.2. Pay attention to water leakage from connection between humidifying equipment and transducer. 注意加湿器与振子相连处水的泄漏 7.3. Only drinking water should be used, if other liquid is intended to use, please contact us in advance. 只能使用饮用水, 如使用其它液体, 请事先和供应商联系 7.4. Design a circuit to guarantee no voltage difference appears between surface of transducer and water. ( Please don t use electrode control for no water control) -5-

6 设计线路使超声波加湿器振子表面和水之间不要出现电位差 ( 无水停机请不要用电极式控制 ) -6-
