Summary: The BE550 has only 1 wide plug for surg and battery. Design problem because routers, DSL modem and others all have wide plug adapters. Product does not address current network equipment design.
No schematic nor Replacement parts for any APC pro

Summary: I had to buy this because a fuse vaporized when the recharging transformer blew open. Shame on APC for being so stingey to return the favor I will be not be buying a part from them but from digikey or futurlec.
Summary: Three year warranty is a plus! The unit does provide good surge and battery backup protection, but there is one drawback. All 8 outlets are not fully accessible because they are spaced so closely together! Three of the four in each row are close and not usable if your peripherals have the larger 3-prong plugs. Of course many of my printers and add-ons have the big transformer plugs and I didn't think they would fit.
Summary: Overall the product serves as an entry level UPS but be careful with the 330W spec. If you want to connect a desktop with lots other device, it wont make it. Also be careful half of the outlets operate through battery so you cant even use it after removing battery i.e.
Pros: Serves as a surge protector even if you dont use the UPS function. The stored power is enough to drive 330W so most desktop should be fine as long its not those powerful gaming machine
Cons: Half of the outlets are connected to battery and cant be used if battery is removed They HAVE to function THROUGH battery. The beep is quite annoying when battery has no power and there is no way to pause it.
Summary: The instructions for connecting battery seem to apply to a slightly different model. In step 2 of Connect Battery, I was unable to remove the battery from the unit. With some difficulty, I slid the battery wire onto the battery terminal.
Conclusion: Не соглашусь по поводу розеток - мой утюг еще тех времен отказывается вставляться в них без переходника, плюс старенький холодильник днепр 2м - точно также себя ведет. В остальном все по правде. И реагирует на скачки напряжения немедля, и долго держится в автономном режиме, и места занимает совсем немного.
