The person and equipment safe protection solid sensing switch
When the temperature of the chipincreases to theset value, Teledye is programming sensed by TSC620 temperature sensor switches. When it reaches the high set value, MOSFET connected, then electric fan is connected. When it's temperature reaches the low set value, it closed. Access a 90kΩ to 200kΩ resistancebewteen each program design input terminaland thepower of High-low temperature set value determining. When the temperature rises, low limit output frist increases, then high output just become higher. When the chip's temperatureis downto below the program design value 2℃, limit outputs respective becomes low.
