Metered Power Distribution & Dual Light Module




Presenting the 4×4 PRO USB SERIES Power Distribution Systems from ART. Built on the foundation of the popular 4x4s, the PRO USB SERIES are durably constructed, reliable power conditioners for use in many applications. Wherever power management system is required, the 4×4 PRO USB  SERIES provide the surge protection you need to keep your rack safe from unwanted disruption.

All PRO USB SERIES models have an additional internal discrete module called APF™ (Advanced Power Filtering) which filters out digital and dimmer hash as well as any high frequency noise that is above the audio range. Some off-the-shelf add-on modules saturate and lose their filtering effectiveness as the load increases, but by using a high power discrete design we were able to create a filter that stays effective over the full operating range.

By using both Common Mode and Differential Mode topologies in series for the filter design we are able to block virtually all of the unwanted noise that is between the AC line and ground, and also the two sides of the AC line. This has the additional benefit of reducing ground loop problems in your system. High frequency noise currents in particular are highly attenuated in both directions so that any line noise that could be generated by one of your components is not allowed to get back into your main A.C. wiring so if you use a number of PRO USB SERIES Power Conditioners in your setup, you can distribute and isolate the noisy components from the sensitive components in your system. Additionally, any signals above 10kHz are filtered from the line with over 40dB of attenuation above 100kHz and beyond.
