产品性能及原理:

本公司生产的KSD305温控器,是由双金属片感温突跳单刀单掷型温度控制器。该控制器由绝缘外壳、金属盖、双金属片、触桥、弹簧、动作杆,构成的单极型的常闭开关。当温度变化升高达到双金属片预设变形温度时,双金属片动作通过动作杆使触桥与触点分离,使得原来呈常闭状态的开关断开。其断开温度可根据客戶之需求而制作,动作后需手动复位使其闭合。

The KSD 305 series thermostat produced by our company is a snap SPST thermostat which adopt the bimetal disc as the tempareture sensing element,being made of insulating case,metal cover,bimetal disc,contactors,mechanical spring pin. 1 pole normally closed switch.When the ambient temperature raises to the preset operation temperature ,the bimetal disc deforms to jump and press the pin, make the two contactors separated,making the original closed switch open then. The open temperature can be designed as client request.When the contactors open,it need manual reset.

注意事项

采用接触感温式安装, 安装时使金属盖平面贴紧于发热体的安装面。

安装时不可把盖面压塌变形,以免影响性能。

使用时不可让液体渗入温控器內部,以免影响电气可靠性,以防止漏电伤害。

本产品为单极接线方式,使用时应按照标识符号,正确接线。使用额定电流不可大于40A。

产品应在相对湿度小于90%,环境温度40℃以下通风、洁净、干燥、无腐蚀性气体的仓库中密封存放。

Adopt contact feeling temperature installation. Please keep the metal cap firm with the installation surface of the heating element when installing.

Don’t distort the metal cap in installation to avoid performance decrease.

Don’t let liquid go into the temperature controller to avoid the electric reliability and leakage damage.

Please connect the cable correctly in accordance with the instruction signs. The used rated current should be less than 16A.

Keep the product in clean dry warehouse at good ventilation and free of corrosive gas and with relative humidity less than 90% and environment temperature under 40℃.
