[rescue] help me find info on this UPS

[Patrick Giagnocavo +1.717.201.3366]

I have a number of what appear to be pretty hefty UPSes.

They take 8x 12V 7AH Yuasa sealed lead acid batteries.  By contrast,
the APC's seem to take only 4 of this kind of battery (RBC12), making
me think it would have a decent runtime were I to get it working.  

It also has 48VDC output on the back, so I could see this being useful
for those of you with Netras that use 48VDC (I have more of these than
I need and could part with 2 or 3 of them).

The batteries are obviously quite dead, the plastic casing on some of
the batts is even warped or bulging out in some cases.  On one UPS,
there is written in black marker "batteries replaced 3/21/00" so
obviously ...

www.upsonic.com.au (only URL I can find) is of no help.

Here is what I have:

Upsonic System 100 A-Series

on the back of the sheet metal case:

fan grill

below left outlet:
AUX AC OUTLET 120V/10A MAX

bottom left:
AUX DC OUTPUT 48VDC

middle:
two pullout fuses, lettering says: DC FUSE 32A/500VDC

middle at bottom:
screw-out fuse, lettering AC INPUT FUSE 10A/125V

right:
output terminals for 48VDC, lettering DC OUTPUT 48VDC

right bottom: cord that goes to normal AC outlet


ANY help greatly appreciated.

Cordially
