In the ascendant, honesty and keeping promises; creating social value!

Since the advent of electrical appliances,It brings a lot of convenience to life.butIf you use electricity unsafely,causeSomeMore seriousquestion,Especially in summer, it is easy toCause a fire。

However, with the advancement of technology,The market began to appearCurrent temperature protector, which is specifically used forensureSafe use of electricity,So what is it exactly?Next StepsLet usLet's find out！

Power supplyCurrent temperature protectorA protection system that shuts down a power supply when the internal temperature exceeds a safe value. Circuitry is used to monitor and generate a trigger signal to initiate the shutdown process in the event of high temperatures. High temperatures can develop within a power supply due to a variety of factors such as faulty components, overloading, overvoltage in the power supply, cooling system failure, ventilation obstruction, or other factors that stress components.

Sustained high temperatures are undesirable and may cause malfunction or further damage to the power supply, connected circuits, or downstream equipment.Current temperature protectorIt ensures that the power supply operates within the safe design temperature range and shuts down the power supply if this temperature is exceeded.

Current temperature protectoris throughFocusAtPCBThis is achieved through temperature control, housing, and heat sink design. Added overtemperature protection extends the life of power supply components, thereby improving efficiency and reliability. Protection is implemented in various ways, depending on factors such as the amount of space, noise requirements, regulatory agencies, and other standards compliance.

Essentially,Current temperature protector(For exampleNTCorPTCThermistors, integrated circuits, on-chip diodes or diodes) are used to protectLEDThe devices and even the power supply units in the application are protected from overheating. The sensor monitors the temperature of hot items on the board. Once the internal temperature exceeds the preset limit,OTPThe power supply is shut down, thus preventing further temperature increase and possible damage.

In typicalOTPIn a system, a pair of thermistors is usually connected to the heat sink. One of the thermistors is connected to the fan control circuit, which is used to automatically adjust the fan speed according to the temperature of the heat sink. The other thermistor is connected toCurrent temperature protector, if the temperature exceeds the safe value, the shutdown process will be triggered.
