I have a Magnavox MDR-513 which currently is on surge suppressors with my other AV equipment. I’ve gotten a recommendation to place the 513 on a filtered UPS but after studying the UPS threads in this forum and elsewhere, I’ve found the recommendations about placing AV devices on battery backup UPS to be conflicting and quite confusing. I would also add that I live in an apartment in an area prone to power surges and severe electrical storms.
First of all, the AV equipment I have running is the following:
3 Tuner Moxi – 80 watts
Vizio VT420M – LCD TV - 160 watts
Comcast – DCH3200 – HD STB – 24 watts
Magnavox – MDR -513 – recorder – 33 watts
Panasonic – DMR – ES45VS – recorder – 29 watts
That is a total of 326 watts if everything is running at the same time, which could easily happen. If I happen to have my old MAC1700 amp/pre-amp/tuner running, that would add an additional 270 watts, or a total of 596 watts. The minimum wattage if everything is off or on stand-by would be around 90-95 watts since the Moxi is fully powered and obviously on 24x7.
This is where the confusing part comes in for me however. After studying the various UPS devices and brands, I settled on the Cyberpower CP1350PFCLCD UPS which has pure sine wave, line interactive, AVR and EMI/RFI filters among other features that I would like to have. It also has 810w capacity which provides a little extra room for growth over my current max watts load. If anything, that device may even be a bit of overkill for my situation.
I became concerned when I found the following statement from APC in a thread in this forum however: http://www.avsforum.com/avs-vb/archi.../t-992865.html
“I understand your concern. As per inquiry, APC does not recommend to connect Audio-Video Equipment to a Back-UPS. For such equipment APC provides a different range of Products called as Audio-Video Solutions. The reason being that Back-UPS is designed specifically for IT equipments, and the Power generated by Back-UPS can in turn harm the sensitive equipments like projector. More over if an Audio-Video equipment gets damaged while being connected to a Back-UPS, then APC will not be liable for the damages caused.”
In other words, APC is recommending their “Audio Visual Solutions” products, which are power conditioners and not UPS devices (and which are also more expensive than UPS devices). Tripp-Lite and other manufacturers also make these devices, which I guess are basically surge protectors.
The basic questions I have regarding my situation are:
- Is the Cyberpower CP1350PFCLCD UPS a risk in terms of possibly damaging my AV equipment as APC states or are they merely doing CYA as that thread seems to think they are?
- If APC *IS* correct in that statement and a UPS would in fact be a risk in my situation, what would others here recommend as a good surge protector and/or power conditioner solution for my situation?
- If the APC statement is NOT correct and a UPS would not be a risk for my equipment, is the Cyberpower CCP1350PFCLCD significant overkill for my situation? For example, do I need to spend the extra money that it costs to get the full sine wave capability that this UPS has? I thought that even though my devices technically don't require battery back-up as a computer would, having that added back-up capacity could help prevent problems with my Moxi (which is always on) or the recorders if they were in the process of recording when a power problem occurred. Would a smaller, less expensive UPS (or even a non-UPS solution) be adequate for my situation?
Regardless of what ever solution I end up with for my AV equipment, I plan to also get another Cyberpower CCP1350PFCLCD (or perhaps the next larger model) for my computer equipment, which has its own separate power requirements and for which I think the Cyberpower UPS would be well suited.
Thanks for any feedback, suggestions or help anyone can provide. I found several other threads in this forum which I thought CAME CLOSE to answering my questions, but none answered them completely. As I mentioned earlier, I am fairly well confused by all of this at this point.
