For powering professional audio devices in environments such as digital recording studios, Equi=Tech markets the Son of Q shelf or rackmounted balanced power system. This line is a more recent variant of the company’s flagship Model Q and consists of the original 1500W 15A version, the 1000W Son of Q Jr. and the 20A 2000W Son of Q Sr. The unit’s front panel features an input power switch and an output power switch, each with its own LED power indicator. Models in the Son of Q line are designed for small-to-medium-sized AV systems and use bifilar wound isolation transformers along with magnetic and faraday shielding.
The rackmounted ETA-S15L AC power conditioner and distribution unit from ETA Systems provides nine AC outlets, eight of which are switched on the rear panel while one is unswitched on the front. Also featured are RFI and EMI filtering. The unit can suppress voltage spikes up to 6000V. There is a 15A circuit breaker on the front panel in addition to the power switch, pullout light, power LED, AC fault LED, and two position light intensity switch. The rear panel offers an XLR connection for the optional Atlas Power AP-GNL18 light with accompanying switch. The unit is rated for a maximum surge current of 6500A and a maximum spike clamp response time of 1 nanosecond.
For home theater and professional audio and video systems, the EP-WSC-15R wide spectrum multistage conditioner from Exact Power uses a series of filters to reject common mode and differential mode AC noise and RFI from incoming power. The unit incorporates custom-wound, heavy duty toroidal inductors and five-stage, high-voltage surge protection along with cable TV and phone line transient protection on three pair of rear-panel coax connections. A twisted-pair in/out connection for surge protection on network and phone lines also is included. The chassis weighs 40lbs. and fits into a 2RU rack space.
Furman Sound designed the PL-PRO DMC power conditioner to provide the maximum function and information in the minimum space. The 1RU rack module features a large digital volt meter/ammeter with discrete dimmer button and LED voltage range warning. The front panel also has dual pullout lights with a dimmer knob and a USB charger connection. The chassis offers eight rear-panel AC outlets and one on the front. The rear panel also has a BNC power connection to accommodate a variety of gooseneck lamps, and three of the rear AC outlets are spaced for wall wart AC transformers.
The RX10-SCS Filtercord from Juice Goose fits behind HD displays to provide voltage surge protection and high-frequency common-mode and normal-mode noise filtration for the best HD picture quality and display protection. The unit’s hybrid filter design protects equipment from surges up to 6000V at 3000 amps on hot, neutral, and ground. If it is connected to an improperly wired outlet, no power will be applied to the load and a wiring fault will be indicated by a red light.
For protection of sensitive electronic equipment from external or internal transient activity LeGrand markets the Wiremold Sentrex ZoneDefender PRO ZPA and ZPB series panel protection devices with EMI/RFI filtering, remote indication contacts, and an audible alarm. With up to 160kA surge protection per phase, the units provide all mode protection housed in a NEMA 1-, 2-, 12-, 13-rated metal enclosure and include short circuit and thermal fusing.
Another entry in the 1RU rackmounted category, the ACSPR-RPC1-1509K from Lowell Manufacturing adds remote control to surge and over/under voltage protection and RFI/EMI filtering. The unit can be operated with a remote switch closure and through a trigger voltage provided by a separate control or fire alarm system. The front panel features a series of LEDs that indicate AC line voltage from levels less than 100VAC to more than 140VAC, and there are shutdown and surge protection status LEDs as well. A power status indicator and 15-amp circuit breaker are included on the front, and the unit may be ordered with either rocker or key-switch power activation. There are eight outlets on the back and one on the front panel.
