I have a 20 AMP/120V circuit. The only device plugged into this circuit is a 1000 Watt Dell UPS. Right now several devices plug directly into the 1000 Watt UPS.
I wanted to order a PDU to help untangle my cabling a bit.
If I order a 16 amp PDU, it seems like I could accidentally overload the UPS (just as I could by plugging items into it directly).
I was wondering if one of the two things existed:
- A PDU suitable for use in a Dell full-height rack rated @ 120V/8 AMPS OR
- A PDU with a configurable shut off point. (One I could configure to shut down at 8 amps even though the PDU is rated much higher.)
I had a conference call with a Dell and APC rep, who suggested that no such thing exists and implied that it's unnecessary for my situation.
Why is this unnecessary for my situation? To me relying solely on whatever overload protection mechanism the UPS has seems a bit scary. Am I being overcautious and/or misunderstanding the situation? Also, does a PDU like the one described exist (even if not available through Dell)?
