Dent Fix Equipment DTF-DF-601 Vehicle Surge Protector

This item is brand-new, factory sealed.

• Acting like a sponge to soak up electrical surges, this unit protects sensitive electronic components when mig and spot welding on a vehicle. An Absolute must when jump starting.
• The DF-601 surge protector passes the electrical current along from the battery to any number of electrical and electronic devices connected to the power circuit. If the voltage from the circuit surges or spikes -- rises above the accepted level -- the surge protector diverts the extra electricity into the batterys grounding terminal.
• A component called a metal oxide varistor, or MOV, diverts the extra voltage. A MOV forms a connection between the hot power line and the grounding line.
• An MOV has three parts: a piece of metal oxide material in the middle, joined to the power and grounding line by two semiconductors.
• These semiconductors have a variable resistance that is dependent on voltage.
