Circuit Protection Element

This unit is equipped with positive-characteristic thermistors (power thermistors) as circuit protection elements.
The positive-characteristic thermistor limits the electric current flowing through the circuit as the internal resistance
increases when an excessive current flows or when the ambient temperature increases.
If the positive-characteristic thermistor works, turn off the main power of the unit and inspect the internal circuit of the
unit. After the cause of the fault is eliminated and the positive-characteristic thermistor is cooled down, turn on the main
power again. The unit works normally. It takes about one minute to cool down the positive-characteristic thermistor
after the main power is turned off.
