TMOV Varistor Application Examples
The application examples below show how the indicator lead on the
i
TMOV can be used to indicate that the thermal element has been
opened.This signifies that the circuit is no longer protected from
transients by the MOV.
Application Example 1 (Figure 1)
In this case, the LED is normally on, and is off when the thermal
element opens.
Application Example 2 (Figure 2)
This circuit utilizes an optocoupler to provide galvanic isolations
between the
i
TMOV varistor and the indicating or alarm circuitry.
Application Example 3 (Figure 3)
This circuit illustrates the use of the monitoring lead of the
i
TMOV
varistor to ensure that equipment is only operated when overvoltage
protection present. In normal operation the load switch relay solenoid is
powered via the indicator lead of the
i
TMOV varistor. In the event of the
thermal element being activated, the relay will de-activate, cutting power
to the protected circuit and the fault LED will illuminate.
Please note: Indicator circuits are provided as a guideline only.
Verification of actual indicator circuitry is the responsibility of the end
user. Component values selected must be appropriate for the specific
AC line voltage service and application.
