  • 【temperature range】 KSD9700 plastic probe temperature control switch is normally open type 250V / 5A, with a complete temperature range, including all specifications between 40 to 100 .
  • 【working principle】 KSD9700 uses a bimetal as a temperature-sensing body. When the temperature rises to a certain value, the piece jumps, the moves quickly, and the circuit is disconnected. When the temperature drops to a certain value, the bimetal resets and the Also restored to the original state, to achieve the purpose of making the circuit.
  • 【high sensitivity】 KSD9700 temperature control switch is light and compact, with high accuracy of disconnection and reset, and .
  • 【features】 KSD9700 thermostat adopts the closed thermostat developed by imported thermal bimetal, and the temperature control action is rapid.
  • 【use】 KSD9700 temperature control switch is mainly used for low-power fractional horsepower motors, computer communications, fans, air conditioners, electric heaters, motors, etc.



Product Description

ksd9700 thermal switch

The KSD9700 heat protection device has the characteristics of small volume, shell insulation, sensitive action, and long life. The thermal protection device is composed of a dual metal component with a thermal ceramic shell, a welding of silver alloy contacts, conductive brackets, insulating fixed seats, static tactics and heat -resistant wires.

The fully enclosed structure can prevent the components from polluting dust or impurities. When the current is over, the dual metal component with impedance. When the non -normal work, when the current increases or the surrounding temperature rises to the set temperature value, the dual metal components quickly move, turn on the contact, and cut off the circuit. When the device is cooled to the safe operating temperature, the contacts are automatically closed to restore the normal working state.

no thermal switch

Temperature detection method:

Connect the two leads of the sample to the fixture of the test equipment, turn on the current of about 10mA (not more than 100mA), and use a LED to indicate the current on and off.

Then put the sample into the special temperature measuring equipment. (The temperature in the testing equipment should be uniform, and the heating speed can be controlled) The thermometer probe should be close to the sample, and control the temperature of the testing equipment to rise at the rate of 0.5~1 ℃/min. When the LED goes out, record the thermometer reading as the action temperature of the sample.

Technical parameters: Operating Temperature: 25-180℃ (one step for every 5℃)

Description of Reset Temperature:

When the operating temperature is below 75 ℃, the reset temperature is the operating temperature minus 20 ℃+15 ℃;

When the operating temperature is 75 ℃~100 ℃, the reset temperature is the operating temperature minus 30 ℃ ± 15 ℃;

When the operating temperature is above 100 ℃, the reset temperature is the operating temperature minus 40 ℃ ± 15 ℃;

As it is a mechanical switch, according to the industry regulations, every 5 ℃ is a gear.

It is widely used for the overheating and overcurrent dual protection of fractional horsepower motors, hot water appliances, fluorescent lamp ballasts, transformers, automobile motors, integrated circuits and general electrical equipment.

Attention:

1. When the contact temperature sensing installation is adopted, the product shall be closely attached to the installation surface of the controlled appliance.

2. Do not collapse or deform the plastic or metal shell during installation to avoid affecting the performance.

3. In the installation of metal shell products with insulation jacket, the external insulation jacket shall not be removed or broken to avoid electric leakage and ensure safe use.

4. When the product is used in a circuit with a current not greater than 5A, the conductor with a copper core section of 0.4-0.75 mm2 shall be selected for connection.

5. The product shall be stored in a ventilated, clean, dry place without corrosive gas where the relative humidity is less than 90% and the ambient temperature is below 40 ℃.

Had them on my wish list so my wife bought them for me. I use the 40c n/o to operate a fan to cool a mobile radio for transmit on GMRS running 30 watts. Works great, tested it on the bench before putting it in service. Mine came on at 40c and off at about 39c.

Long story on what I'm using it for, but it does allow the fan to turn on at the appropriate temperature (50c), but doesn't turn off. I've had it drop below 20c and it still wants to run. Unplug it and then plug it back in it stays off until it reaches 50c again, but it's frustrating.

I used this on my sunlu filament dryer. When it heats up now it will kick on some fans to circulate some air. The dryer gets much hotter than it use to. So far this has been great.

Installed on a Sunlu Dryer to start a fan but it starts the fan but after the temperature cools down the fan keeps working.

I did not measure how precise it is, but it does not matter since it works well to silence fans when the amplifier does not play loudly.
