Alpha’s surge protection devices provide reliable protection of power supplies and related equipment from the damaging powerline disturbances common to cable TV and broadband applications. The LA and ISA Series incorporate Metal Oxide Varistors (MOVs) that effectively limit voltage surges and absorb excessive energy levels. Housed in durable polymer casings with standard electrical plugs, the LA Series plugs directly into any electrical outlet, while the ISA is factory wired into the service entrance.

  • Critical protection from voltage transients
  • Modular and hardwired Metal Oxide Varistors (MOV) options
  • Convenient, plug-in design for easy installation
  • LA Series features piggyback plug to optimize receptacle use
