Loaded with a generous combination of high-quality components, a near indestructible all-metal case and unique noise filtration system, the Isobar offers the highest level of protection attainable in a multi-outlet strip. Robust surge suppression circuits with sine-wave tracking offer extreme levels of protection against the heaviest surge conditions, exceeding IEEE 587 category A/B specifications and reducing 6,000V test surges to harmless levels under 35 Volts. The Isobar's unique protection system combines large torroidal chokes, ferrite rod-core inductors, HF/VHF capacitors and multiple layers of metal oxide varistors into exclusive isolated filter banks that remove EMI/RFI interference, along with noise generated by other pieces of connected equipment. This unit offers 4 outlets arranged in two filter banks to prevent system crashes, reboots and performance problems that are common as noisy system peripherals are powered off and on. Surge suppression is rated at 2200 joules (85,000 Amps) and offers network-grade protection. The widely spaced NEMA 5-15 outlets accommodate up to 2 large transformer plugs without blocking outlets. Diagnostic LEDs confirm power availability, line fault and protection status. This unit includes a 6-foot AC line cord with a space-saving angled input plug, keyhole mounting tabs, and a set of 4 child safety covers.
