KSD301 series of sudden jump thermostat

1, the sudden jump-temperature range of applications: KSD301 series sudden jump thermostat widely used in boilers, water heaters, vacuum cleaners, copiers, electric stove, ovens, dryers, refrigerators, dishwashers, air conditioners and other temperature control . 2. Features with stable performance, high precision, small size, light weight, high reliability, long life, and other characteristics of radio interference. 2.1 Action mode normally open or normally closed. 2.3 Reset: automatic reset and manual reset two ways. 3. 3.1 The basic performance parameters electrical parameters AC 220V / 16A, 50 / 60Hz 3.2 Temperature 3.2.1 Temperature characteristics Operating Temperature: -20 ~ 300 ℃ Tolerance: ± 1 ~ 2 ℃ 3.2.2 Test Method Products Terminal insertion test station detects socket station inside, covered test bed cover, and set it to start the test station detects temperature ,, heating or cooling of the air by computer-controlled heater, heating and cooling rate control in 0.2 ~ 1.0 ℃ / min, the product through the air induction temperature until the product reaches the temperature of its action action. 3.3 In the case of insulation resistance 500V DC voltage is applied to test the insulation resistance ≥100MΩ charged metal and bakelite housing. 3.4 Electric strength applied to a frequency of 50Hz or 60Hz fundamental sine wave voltage 1500V for 1 minute (or voltage 1800V lasted 1 second) no flicker, no breakdown in the case of room temperature. 3.5 Grounding through the thermostat cover stainless steel metal parts connected to the equipment grounding. 4. Notes 1, the thermostat should be operating in the air relative humidity less than 90%, non-corrosive, in the presence of flammable gas and conductive dust environment. 2, using contact temperature thermostat, should it cover against the accused heating appliance parts and should be coated with thermal grease, or other properties like heat medium temperature at the surface of the cover. 3, temperature control through the contact with the liquid or steam temperature, stainless steel cover products should be reliable and leak-proof measures to prevent fluid leakage to the thermostat insulating member. 4, the installation process can not cover the top of the sag or deform, so as not to affect the product temperature and other properties. 5, using the transportation and installation process should be protected bimetal good leakage when bald cap, so as not to damage the bimetal cause the product temperature changes. 6. Do not allow liquid to penetrate inside the thermostat. Housing must avoid excessive pressure to prevent cracks; housing should be kept clean to prevent contamination of conductive material, so as not to be degraded insulation breakdown and short circuit. 7, using the process can not bend the terminals, otherwise it will affect the reliability of the electrical connection and contact resistance.
