Tripp Lite ULTRABLOK428 IsPRar Ultra Surge Protector/Suppressor 15-Amp 2 outlets Direct-plug 600 Joules

Loaded with a generous combination of high quality components, near indestructible all-metal case and unique noise filtration system, Isobars offer the highest levels of protection. Robust surge suppression circuits with sine-wave tracking offer extreme levels of protection against the heaviest surge conditions. Isobar's unique protection system combines large torroidal chokes, HF/VHF capacitors and multiple metal oxide varistors that remove high level surges and EMI/RFI interference. UltraBlok 428 offers 2 outlets arranged with standard wall socket spacing in a cordless direct plug-in format. Mounting tabs allow permanent connection via duplex switchplate screw. Surge suppression rated at 600 joules / 48, 000 amps offers high-grade protection. Diagnostic LEDs confirm power availability, line fault and protection status.

Have been using Tripp Lite surge surpressors for over 15 years on computer and other expensive electronics and never had a failure or damage. (Their Isobar line is tops in my book.) The Ultrablok428 is now standing guard on my new Sleep Number bed. No worries! Nice compact but heavy duty plug-in unit with clear status lights.
