The SA-15 and SA-20 are specifically designed to upgrade and improve surge protection for audio, video, computer and all sensitive electronic equipment. These standalone units when fitted with optional mounting brackets easily mount where you need them. The SA-15 rated for 15 amps and the SA-20 rated for 20 amps both feature two industrial grade grounded AC receptacles and feature Impedance Tolerant® EMI/RFI filters. SurgeX patented advanced Series Mode Pro™ technology is superior to conventional MOV circuitry. Both units provide proven, reliable protection: blocking and containing surges of up to 6,000 volts, unlimited current, without noise producing ground contamination. The SA-15 and SA-20 meet the most stringent government purchase specifications for AC powerline surge suppressors. The A-1-1 rating assures you of dependable protection from destructive spikes, surges and inductive transients.
