Metal Oxide Varistors (MOVs)
Have Darrah mount a Metal Oxide Varistor (MOV) to your Contactor to protect your SCR's from transient voltage surges. MOV's are ideally suited to welding applications. Their higher clamping efficiency and low steady state power dissipation offer considerable advantages in protecting the SCR Contactor and control circuitry. Darrah's MOV's feature high surge current capacity, instantaneous response in a compact and robust package. Selection of the MOV is governed by incoming line voltage and SCR voltage rating (PIV). Available in PA series or LA Series types.
