DITEK is showcasing its Deflector Series Surge Protective Devices at ISC West 2019. The Deflector surge protector notifies the user three ways when it?s time for service. Unique rapid-replacement modules make it possible to have the unit up and running again in only a few seconds. The DTK-DF120S1 Deflector Series Surge Protector is a 120-volt dedicated circuit protection device designed to minimize damage from AC supply voltage spikes by isolating incoming surges that originate from lightning strikes and other sources.
