0LKS400.V Datasheet/PDFOLKS400.V is an integrated electronic fuse that adopts a fast-blow type. It can protect the circuit from overload, short circuit and over temperature caused by the failure of other components. It is widely used in audio-video equipment, power supply, household appliances, DC motor, automobile,etc. This article introduces OLKS400.V\'s specific application fields and working principle.
OLKS400.V is mainly applied to various kinds of power supply circuits, DC and AC mixed circuits,circuits with extra large current. It has some special protection and fault indication features. For example, its OVFT (Over Voltage, Failure Alarm and Trip) over-voltage protection can protect various incidents causing insulation breakdown of the circuit. In DC motor applications, it can effectively prevent brush burning and motor overload due to the stall of the motor, or at the starting time due to insufficient power supply.
The working principle of OLKS400.V is mainly based on the electromechanical operation. When the external overload, short circuit or over temperature occurs, the resistance temperature coefficient (RTC) in the fuse element is changed, resulting in the increase of current in the element. These changes can cause the fuse element to thermally expand, resulting in a large increase in resistance. In this way, it can quickly disconnect the current within the time limit and protect the circuit from fire accidents caused by overload, short circuit or over temperature. In addition, OLKS400.V has the advantage of high temperature tolerance. In special occasions, it can operate normally in a temperature range of -40 to +125 degrees.
Apart from its application and working principle, OLKS400.V also has some other advantages. For example, the direct-mounted installation structure of the fuse element is very small and space saving, and it has high reliability, the failure rate of which is very low. In addition, it has perfect arc-extinguishing characteristics and no risk of electric shock.
OLKS400.V is widely used in many industries due to its strong performance and wide application range. In addition, its environmental friendly design is also very important. In conclusion, it is a very popular electronic fuse product that can be used in many fields such as power supplies and audio-video equipment.
