KSD309系列

KSD309系列
适用范围：

KSD309突跳式温控器中动作温度最高的系列，达280°C；结构紧凑，体积小，非常适合于高温的小家电产品如烤箱、多士炉、微波炉等。

KSD309系列产品分为两个子系列，分别是单温型的KSD309-A和双温型的KSD309-B。

技术参数：

1.1.1      额定电流（阻性）  Rated current: 10A, 16A (resistive)

1.1.2      端子间电阻  Resistance Between Terminals

80mW以下（数字式毫欧毫伏计，DC10V，1A）

Below 80mW (Numeric mW & mV meter, by volt-ampere standard, DC10V, 1A)

1.1.3      绝缘电阻  Insulation Resistance

用DC500V绝缘电阻表加额定电压DC500V测定大于100MW。

With a DC 500V megger, borne DC 500V, the tested value is over 100 MW.

1.1.4      电气强度  Dielectric Strength

带电金属部件与非带电金属部件之间能承受接近正弦波的2000V 50Hz交流电压历时一分钟的耐压试验，不击穿，无闪络。

Parts between electriferous components and non-electriferous ones can bear 2000V 50Hz AC current, which is nearly sine wave, for one minute as bearing test. Resulted no breakdown, no flashover.

1.1.5      温度特性类型  Class of Temperature Characteristics

常闭、一次动作（双温型中的限温端）。

Normal close, one-shot (the limiting part of the dual-temp. type)

安装和使用说明：

¿ 接地方式：通过温控器金属外盖与设备接地金属部件相连。

Method of earth: By means of the metal cup of thermostat connected in the earthing metal part.

¿ 温控器应工作于空气相对湿度不大于90%、无腐蚀性气、可燃性气体和导电尘埃存在的一般室内环境。

The thermostat should work in environment with humidity not higher than 90%,free of caustic, flammable gas and conducting dust.

¿ 温控器采用接触感温时，应使其封盖紧贴被控器具的发热部位，并应在封盖感温表面涂上导热硅脂或其他性能类似的导热介质。

When the thermostat is used to sense the temperature of solid items, its cover should be clung to the heating part of such items. Meanwhile, heat-conducting silicon grease, or other heat media of similar nature, should be applied to the cover’s surface.

¿ 不可把封盖顶部压塌或使其变形，以免动作温度改变或影响其他性能。

The top of the cup must not be pressed to sink, so as to avoid adverse effect on the thermostat’s temperature sensitivity or its other functions.

¿ 不得让液体渗入温控器内部！壳体必须避免受到过大的力以防止出现裂纹；壳体应保持清洁，防止导电物质污染，以免因绝缘性能降低而发生短路击穿。

Liquids must be kept out of the thermostat’s inner part! The base must avid any force that could lead to crack; it should be kept clear and away from the pollution of electric substance to prevent insulation weakening that leads to short-circuited damages.

¿ 使用过程不能折弯接线端子，否则将影响电气连接的可靠性。

The terminals should be bent, or else, the reliability of electric connection will be influenced.
