Price reduced on clean used IBM Model 1500T 1500 volt-amp 120-volt AC uninterruptible power supply in good working order. Removed from light-duty backup service in November 2024 when alert came on to replace two batteries installed in September 2019. Uses two sealed lead-acid 12-volt batteries with 18 Ah rating, shown in photos but not included. Unit has eight three-prong 120-volt receptacles on rear as well as two Ethernet, one USB and one 9-pin COM jacks. This is a voltage-regulating sine-wave output heavy duty power supply suitable for running equipment with induction/synchronous motors and other 120-volt AC loads that won't work on chopper-based UPS power.

It is clean and very quiet, having been used for 14 years indoors as backup for the electrical needs of natural gas heaters.
