ART SP 4×4 PRO LED Metered Power Distribution SystemMore about the item Presenting the 4×4 pro series power distribution system from Art. Built on the foundation of the preferred 4x4s, the SP4x4 Pro is a durably constructed reliable power conditioner that can be utilized in many applications. Wherever power management system is required, the 4×4 pro series give you the surge protection you wish to have to keep your rack secure from unwanted disruption. The SP4x4 Pro has an additional internal discrete module known as APF™ (Advanced Power Filtering) which filters out digital and dimmer hash in addition to any high frequency noise that may be above the audio range. Some off-the-shelf add-on modules saturate and lose their filtering effectiveness as the load increases, but by the usage of a high power discrete design we were in a position to create a filter that stays effective over the full operating range. By the usage of both Common Mode and Differential Mode topologies in series for the filter design we may be able to block virtually all the unwanted noise that may be between the AC line and ground, and also the two sides of the AC line. This has the additional advantage of reducing ground loop problems in your system. High frequency noise currents in particular are highly attenuated in both directions so any line noise that may be generated by one of your components isn’t allowed to get back into your main A.C. wiring so if you use a lot of PRO SERIES Power Conditioners in your setup, you’ll distribute and isolate the noisy components from the sensitive components in your system.Main Points APF – Advanced Power FilteringPull out light pipes with AutoOff and dimmerEasy to read LED input voltage meteringPower capacity of 1800 wattsSurge & spike protectionMore Info Manufacturer: ARTShipping Weight (pound) : 7.3 Shipping Dimensions: Width: 9.60 Length: 21.70 Height: 2.90 Payment Our Guarantee Shipping Returns Feedback Contact Us We accept Paypal only All major credit cards are accepted through Paypal’s safe payment system Payment with Paypal is instant and offers buyer protection, so you never want to worry about your purchase!
