TVS Lite 1000

Performance. The TVS is average as far as performance is concerned. It qualified at 90 percent of its rated load. It’s output voltage to the load is acceptable, but the range could be further reduced. It’s upper and lower switchover voltages, though, were very good. The backup time is about 4 minutes, and the float voltage is also within the specs. It, of course, passes the droop voltage.

Features. This is the most feature-filled UPS we tested. It comes bundled with the control software, and plenty of LED indicators. Plus, it has many additional features like telephone surge protection jacks, one surge protection outlet for devices like printers, and even an indicator in the rear to indicate wiring fault if any. It’s highly compact and comes with good documentation.
