Lead Configurations
TMOV34S
The application examples below show how the monitor lead on the TMOV34S
element has been opened. This signifies that the circuit is no longer protected from transients by the MOV.
Application Example 1
thermal element opens.
Application Example 2
This circuit utilizes an optocoupler to provide
galvanic isolations between the TMOV34S
varistor and the indicating or alarm circuitry.
