5.Lifespan : ≥100,000 times
6.Electrical parameters :1) CQC ,VDE ,UL ,CUL AC250V 50~60Hz 5A/10A / 15A ( Resistance load )
2) UL AC125V 50Hz 15A ( Resistance load )
7.Contact resistance : ≤50mΩ
8.Insulation resistance : ≤100MΩ
Junction method : Constant-closed : the contact point disconnects when temperature rises ; and contact point connects when temperature falls ;
Constant-opened : the contact point connects when temperature rises; and contact point disconnects when temperature falls .
10. Casing protective class : IP00
11. Grounding method : Connection is made between the metal casing of the temperature controller and the metal part of the grounding device .
12. Installation method : installed for KI031 series : general moving ring, mini round moving ring, flat moving ring general aluminum cover with mounting hole , extra length aluminum cover with mounting hole .
Structure and application :
KI-31 serial products are the temperature controllers taking bimetallic strip as the temperature-sensing unit . In case of normal operation the electrical appliance , the bimetallic strip is in a free state; the contact point is in a state of close / open . When the temperature reaches the action temperature, the bimetallic strip performs quick action generates caused by internal stress due to heating; open/close the contact point; disconnect / connect the circuit ; thus , the temperature is in control . When the electrical appliance is cooled to the recovery temperature , the contact point automatically opens/closes to recover normal operation state .
Widely used in electrical heating appliances like water dispenser , water heater , sandwich bread baker , dishwasher , dryer , sterilizing cupboard , micro-wave oven , electric heating coffee pot , electric cooker , refrigeratory , air-conditioner, laminator, heater of auto seat .
Product Structure :
Characteristics :
Stable performance , high accuracy , small size , lightweight , high reliability , long lifespan , less interference to radio
Precautions :
1. When adopting contact temperature sensing installation , the surface of the metal cover is required to be securely contacted with the installing surface of the controlled device . For ensuring the temperature sensing effect , it is required to coat thermal conductive grease or other similar thermal conductive medium on the surface of temperature sensor .
2.For reliable performance, collapse , loose or distorted top part of the cover is prohibited during installation .
3.Liquid inleakage into the controller , crackle in the casing and unauthorized change of external terminal position are prohibited .
4.When the product is used in the circuit with maximum current of 5A , the cable with copper core at section 0. 5-1mm2 is required for connection ; When the product is used in the circuit with maximum current of 10A, the cable with copper core at section 0.75-1.5 mm2 is required for connection ;
5.The product should be kept in a clean , dry and corrosive gas-free warehouse with good ventilation and at relative humidity below 90% , environment temperature below 40 .
