V390MA3A

The V390MA3A is a metal oxide varistor (MOV), a device that is well-known for providing a wide range of protection against electrical noise, transients, and surge currents. As an MOV, the V390MA3A has a diverse range of potential applications, from lightning and surge protection, to filtering out noise from the power supply. In addition, the V390MA3A is notable for its clamping voltage range of 22 to 390 volts.

The V390MA3A is designed to protect electronic equipment from unexpected changes in voltage, either from environmental sources or from power supply fluctuations. Its simple design consists of a series of zinc oxide elements which are encased in a cylindrical plastic housing. When an excessive voltage spike is detected, the MOV springs into action by diverting the current away from the equipment.

The V390MA3A utilizes a unique clamping voltage range in order to ensure effective protection from electrical noise and transients. When an incoming signal that exceeds the MOV’s threshold is detected, the elements of the MOV come together to form an ohmic connection. This connection has the effect of “clamping” the incoming signal, meaning that it does not exceed the threshold of the MOV.

The clamping voltage of the V390MA3A ensures that electrical noise and transients, both from environmental sources and from the power supply, are instantly diverted away from components and circuitry that may otherwise be damaged. This, in turn, helps to ensure that electronic equipment is able to perform as it should, thus providing superior protection against potential damage.

In essence, the V390MA3A provides a versatile solution for those seeking protection from electrical noise and transients. Its unique design and clamping voltage range allow it to effectively protect against unpredictable voltage fluctuations, providing an efficient and cost-effective means of protection against electrical damage.
