LED Power Supplysfyh
LED dimming driver power is widely used in lighting fixtures, and its uniqueness is superior to traditional lighting methods. In addition to improving the quality of life, improving the efficiency of the light source, and prolonging the service life of the lamps, the LED dimming driver also uses its unique dimming function to change the color temperature and brightness of the light, and fully realize energy-saving applications as its greatest advantage. The PWM dimming power supply achieves the effect of brightness level by turning the LED on and off with PWM waves to change the on-time of the forward current.…

The role of using NTC thermistor temperature sensor in electric vehicle lithium battery

sensorsfyh
The use of in rechargeable batteries is to ensure battery performance and safety, to stably monitor the temperature of rechargeable battery packs, and to escort safety!Lithium-ion batteries are very sensitive to “overcharging”. When the voltage at both ends of the battery is too high, it will increase the risk of smoking, burning and bursting of the battery. Aiming at various faults that may occur in the battery, monitor the charging and discharging status of the battery to ensure battery life and performance, and protect the battery and external equipment from damage.The functions of the NTC thermistor temperature sensor in the…
