This rack/table mount power supply switching module is top notch.I didn't realize just how versatile this was until I purchased it and ran it through its' paces.The module comes securely packaged and has an instruction manual that details all of the configuration options and settings.There are 7 outlets that can be configured for delayed power-on functions, and 3 always-on outlets.This allows you to set the delay power-up time for each item powered by the module.There is an option to set the contrast level of the front display, though I found that keeping it at the default setting works best in a normally lit room.On the face of the unit, are LED indicators that provide information about whether the module is grounded properly, if there is an overloaded condition, number of Amps the equipment is drawing, the line Voltage supplied to the module, and of course there is also a power button.The delay time you set for turning power on to each of the switch outlets, is also applied to the power down of those outlets.I use the module to supply power to my tube amplifiers, footswitches and whatever other audio equipment I may be using in my digital audio workstation. I've found this module to be dead silent, not introducing any noise, interference or cross-talk into my system.The module is also over-current protected so you can be certain that lightning or any other power surge will not damage your valuable equipment.All in all I would highly recommend this for anyone powering a home theater, home recording studio or any other situation requiring clean, safe power to your equipment. Great product and great value!Edit: 10/21/19This unit is still simply awesome. I've purchased several thousand dollars worth of studio equipment since I've purchased this power conditioner, so now I need another G5BLK for rack-mount gear. No hesitation whatsoever. I ordered another one of these units to accommodate and protect the equipment in my ever-growing studio. I came upon a comparison recently between this APC and a Furman unit where both were opened to show the difference between them. The APC is a much, much higher quality unit, with completely isolated outlets and associated components. That's why this unit is heavy. All of the case space is used for integral components. The Furman honestly looked "cheap" and fairly empty, and it was more expensive. For my investment, I need quality. This is simply the best you can get under $400.Edit: 11/23/21Both of my power conditioners are still going strong. I have added an RME ADI-2 Pro FS BE AD/DA to my studio for extremely high quality mixing and mastering. To enjoy the sonic benefits of such audio perfection, you indeed need power supplies and conditioners that keep noise levels null. Again, I cant stress enough how fantastic these units are for that purpose. I honestly feel like I found the proverbial diamond in the rough with these. You can easily spend 5 times more and not get better quality nor performance. I have relatively poor electrical in my 58 year old house. But I can literally see bit for bit performance in the software for my UFX+ and I’ve never had a lost bit of information, a crackle or pop in my recordings, or any other anomalies since I started using these power conditioners.I have a lot of faith in APC. Enough to protect more than $20k of gear in my small but ever growing studio.

After having older units of this type from a different manufacturer fail, we decided to get two of these new units for a sound equipment rack in a church performance hall. They are of excellent quality, and we found the programming to be a cinch to get them going. The LCD display is a plus, and we found it best to set it on the screen that provides the amount of power that is passing to the equipment, so we don't have to worry about overdriving the unit. The unit comes with attached rack ears, which we did use but it also is shipped with rubber padded 'feet' if you choose to sit it on a shelf. We can also appreciate the fact that the power that is passed through this unit to our beloved equipment is conditioned and surge protected. Just what we wanted, and the price cannot be beat when compared to more expensive units. We have many different operators come into this sound booth to operate the equipment; these units make the power up/down sequence completely automatic and simplified. We could not ask for more, other than to have the sound mix itself! We felt the quality and features in this unit, the amount of switched outlets, the amount of other useful outlets, and again the LCD information display to be on-par with units that are much more expensive.

OMG... 10 seconds setup, you don't need to read the manual!Good addition to your rack or audio systemYou can monitor your home/studio AC voltage and power consumption of your gearCons:None so far

Great product, looks great in my rack with the on screen voltage and current consumption. Most of all does what it supposed to do however I notice some ground noise when I plugged a treadmill in the same receptacle. There is a grounding connector being the unit so maybe this would most likely sort that out. The only thing I complaint about is the rear always on outlets, I dont see my self having use for these and found they should have made another delay switch or even just incorporate the feature to set it to your needs. I bought this amongst others because of its switched outlets so having always on defeats what I need it for.
