300V AC Metal Oxide Varistor (MOV) 07D471K red If you have basic knowledge

If you have basic knowledge about multimeters then you can try this small multimeter for basic continuity check and voltage measurement and can also be used for heavy ampere measurement in heavy load wires

Ethernet network cable testing is an important part of the process

High Stabilization of Circuit Voltage

The touch Control sensor switchboard is designed with a backlight source

which means the positive terminal voltage must always be larger than the negative terminal voltage

300V AC Metal Oxide Varistor (MOV) 07D471K red If you have basic knowledgeThe Zinc Oxide Varistor (ZOV) is a nonlinear semiconductor voltage dependent resistor that is used in electrical circuits to limit the voltage. Electronic circuits and equipment without (MOV, ZOV, VDR) can be damaged or completely destroyed by transient over voltages. They're mostly found in voltage sensitive electrical gadgets' protection circuits. A varistor effectively bypasses all transient surge voltages and prevents them from reaching the
