APC by Schneider Electric BX950MI 950 VA / 520 Watt Back UPS BX - Uninterruptible Power Supply VA, Battery Backup & Surge Protection, with AVR, Data Function Black

I got this to power my QNAP NAS in case the power goes out. From best to worst- it looks quite nice and as a unit for sitting under a tv, doesn't stand out but the light is a little bright.- USB support is excellent and doesn't need anything special to work out of the box. the qnap saw it straight away and started using it plus my windows pc saw the battery as soon as i plugged it in and started acting like a laptop, which is excellent and allows you some very special power management based on percent of charge and if the power goes off.- When the power goes out, while it isn't full sine, it's not quite as aggressive as some of the other units i've used. you can still hear that it's not full sine but it doesn't sound like it's wringing the neck of the devices connected to it.- Run time is acceptable, i've gotten 10 minutes out of it with more to spare (with about 200w load) and for my use that's all i need, i can't comment on full run time but as this unit uses lead acid batteries i wouldn't ever recommend running them completely flat as that will damage them.- This unit does run quite warm, the AVR circutry seems to give off a fair bit of heat so if you're putting it in a cupboard make sure that there's a fan blowing some air over the unit, i don't think i'd like to see what would happen if the lead acid batteries start boiling.and the worst- You can't change the batteries yourself, i'm sure you can order the replacements but the actual unit is designed in such a way that it's not trivial to replace the batteries, which in my eyes is just stupid. for something that will last max 3 years, that's a poor move from APC and doesn't inspire confidence. for me that's not a big thing as i will be upgrading to another full sine unit in the future but that still leaves a bad taste in my mouth. i wish i knew this before i brought the unit because it's just as important to be able to service the unit as is the quality of how it works.Overall, you'll be well served by the unit for low priority stuff and the USB support is excellent, just a shame about the batteries.

Die USV funktioniert einwandfrei, der Support von Schneider ist gut. Für den Gebrauch im Büro ist die USV meines Erachtens ungeeignet, weil sie einen unangenehm-stechenden, chemischen Geruch verbreitet.Im November letzten Jahres bestellte ich das Gerät. Lieferung und Verpackung wie immer prima. Nach der Inbetriebnahme roch es unangenehm-stechenden nach Chemie. Im Arbeitszimmer war das nicht auszuhalten. Deshalb verbannte ich das Gerät bis letzte Woche in den Keller, in der Hoffnung, dass sich das gibt. Trotz fast zwei Monaten Betrieb stank das Gerät weiterhin vor sich hin, weshalb ich bei Schneider-APC reklamierte. Das klappte prima, der Mitarbeiter im Chat war freundlich und zuvorkommend und innerhalb zwei Tagen hatte ich ein neues Austauschgerät.Das riecht aber genauso unangenehm chemisch. Für den Einsatz im Arbeitszimmer unzumutbar. Schade, bisher haben die seit Jahren genutzten, weiteren APC-Geräte nie Probleme gemacht, diesmal dafür erhebliche.

Bought a BX950MI unit for my pc workstation and monitor. Easy to set up. Comes with a IEC C13 to C14 cable (kettle type plug, male to female) and usb cable. I bought an additional cable for my monitor. Downloaded powerchute software from manufacturers website to set-up and monitor the UPS. Using Win11 do get a User Account Control message every time I want to open the software GUI (dont seem to be able to set an exception) - this isn’t a problem though, just a little annoying. The software does load on startup. Next day had a blackout within my neighbourhood! (quite rare occurrence, maybe once a year). UPS did it's stuff and it set my PC to hibernate (power off). Little annoyances (1) green strip lights on front are a bit bright (as other reviewers have mentioned -black tape will help), (2) pressing of power button is accompanied by rather loud beep - not sure if I can turn this off in the software. Power draw is 20-30 W while PC is on and UPS on full battery. Device can be turned off with 2(?) second button press so will do this after ive switched PC off. Very pleased with the purchase so far.

Ottimo ups acquistato in Black Friday con buono sconto. Qualità costruttiva indiscutibile.

Die Installation ist denkbar einfach, auspacken, gelben Akku-Verbindungsstecker umklappen und einstecken, einschalten, fertig.Das Gehäuse wird handwarm, das ist aber normal und liegt anscheinend an der verwendeten Akku-Technologie. Ca. 15W habe ich als Leerlaufverbrauch ohne angeschlossene Last gemessen.Die Kaltgeräte-Anschlüsse sind für meinen Zweck ideal, die Stromversorgung eines Synology-NAS soll damit hauptsächlich sichergestellt werden.Per beiliegendem USB-Kabel habe ich die USV mit dem NAS verbunden, sofort wurde sie erkannt, die von dem NAS geschätzte Batterielaufzeit ist fast eine Stunde. Bei sinkender Batteriekapazität der USV fährt der NAS automatisch herunter, Datenverlust wird somit vermieden.PC, Router, Switch, etc. können mit dieser USV natürlich auch noch einige Zeit betrieben werden.Für mich ist diese USV die ideale Vorsorge für Stromschwankungen oder kurzfristige Netzausfälle.
