$90 · line regulator / inverter / backup, Powerware true sine 1500VA

Powerware Prestige EXT true sine wave 1500VA inverter / regulator / uninterruptible backup unit. It will work as an excellent line voltage regulator with constant output for input variations from 85v to 130v - with or without batteries. If used as a power fail backup, it has internal space for qty 5 of NP5-12 type (or equivalent 12v 5ah) sealed lead acid batteries, or it can be used with any 60v external rechargeable battery. The unit will charge external batteries. The batteries are gone but the original jumpers are supplied. I kept two for general use as line voltage regulators / conditioners and emergency power backup, but now only need one. It has been fully tested. Also shown is a separate companion battery module (available for an extra $10) that holds qty 10 of the same batteries.
