Вставной варистор реле управления Caterpillar 5021679

A Control Relay Pluggable Varistor is a nonlinear electronic component. It is plugged into a control relay within Machine Electronic Controls and Data Management Systems. In its normal state, the varistor exhibits high resistance. However, when a transient voltage spike or surge exceeds a specific threshold voltage, the varistor's resistance decreases significantly. This allows the varistor to absorb or divert the excess voltage away from sensitive electronic components, protecting them from potential damage.Attributes:• Made to operate with alternating current voltages between 24 volts and 48 volts• Handles direct current voltages ranging from 24 volts to 70 voltsApplications:A Control Relay Pluggable Varistor serves as a transient voltage suppressor made to safeguard the control relay and other electronic components from harmful voltage spikes and surges.
