Needing a new UPS to protect my video edit workstation, I decided to upgrade to a higher power unit that included a pure sine wave output. A search led me to the CST1500S which while a bit more expensive then some of the other units provided me with to advantages I was looking for; one it had enough battery capacity to allow me to continue working threw an outage. Lessor systems only give you enough time to shut down, and I wanted to be able to complete a render or an upload. Two because it would have to power my workstation for more then a few minutes a stepped sinewave was not acceptable. The cpu power supply needed a clean power source and this unit ensured that.
Watch as we unbox and run threw all the buttons and features, plus a real world test of trying to render when the utility power goes out.
