The 15P PTC Thermistor Characteristics Curve
Working Principle
Connect the PTC thermistor in series in the load circuit. When the
circuit is in normal working condition, the current through the PTC
thermistor is less than the rated current. The PTC thermistor is in
the normal state and the resistance is small, which will not affect
the normality of the protected circuit. jobs. When the circuit
fails, the current greatly exceeds the rated current (2 times of
the normal working current), and the PTC thermistor suddenly heats
up, showing a high resistance state, so that the circuit is in a
relatively "off" state for protection purposes. When the fault is
removed, the PTC thermistor automatically returns to a low
impedance state and the circuit resumes normal operation.
Application
Inverter welding machine is more and more popular in the world
since technoloy required for manufacturing. Good protection can
assured inverter welding machine functioning well for long term.
