The PS4x4 Pro USB is the flagship rackmount power conditioner from ART. It features eight rear AC outlets, four of which are widely spaced to accommodate large power supplies, with surge and spike protection to keep your equipment safe.

Features:

- 8x Rear AC Outlets, 1 Unswitched Front Outlet
- 2x 5V USB Ports
- Surge and Spike Protection
- EMI and RFI Filtering
- Advanced Power Filtering (APF)
- Digital Input Voltage and Load Current Meters
- 2x Pullout Front Lamps

- 1U Rackmount

The PS tier has dual digital meters for input voltage and load current, and two pull-out front LED lamps with a variable dimmer and discrete power switch. Pro USB models add an unswitched front AC outlet, two 5-volt USB ports, a rear gooseneck lamp, and an Advanced Power Filtering (APF) module.

APF filters digital and dimmer hash, and any high-frequency noise above the audio range. The custom filter design blocks virtually all unwanted signals between the AC line and ground. This augments the EMI and RFI filtering found in every ART rackmount power supply, providing our most sophisticated power conditioning.

Power your rig with a convenient single switch and give your equipment the protection it deserves.
