Tripp Lite SMART1500LCD 1500VA Rack Mount UPS Battery Backup, 900W, 8 Outlets, PWM Sine Wave, Short Depth 2U Rackmount UPS, AVR, LCD Screen

I bought the 1500VA (non expandable) unit to maintain two Ubuntu home servers during brownouts, short blackouts, and if necessary properly shut down the servers to protect the RAID array data.So far the unit performs as expected. My twin servers draw about 200W average load which gets me 20 minutes run time plus 3+ minutes reserve for shutdown.My only disappointment is in the software. Tripp Lite only provides power management software for Fedora and OpenSUSE Linux Distro's. However, I seem to have found a replacement with Gnome Power Manager which makes the Server think its got a laptop battery. However, there is a delayed response time when the critical battery level is reached and when the Server actually shuts down. For me, the ~30 second delay is no issue, but if your running 900W and only getting 3 minutes out of the UPS, then that could be a problem. I don't think this justifies docking stars as I'm a specific case, but I just want people to know who may find themselves in the same boat as me.Best,Austin

Súper servicio el de PCEL, me llegó rápido y son muy atentos. Un excelente precio, el equipo cumple con lo detallado. Me agrada que a través del display se conozca el estado y rendimiento del equipo. Lo uso en casa para el centro de entretenimiento y ha ido muy bien. En posición vertical luce perfecto.Actualización: es 2021 y no ha requerido mantenimiento ni cambio en la batería. Entra exacto al momento de corte eléctrico. Para que tengamos una idea, están conectados a este UPS, pantalla 55”, home theater 5.1, subwoofer adicional de piso, PS4, blu-ray player, teléfono inalámbrico, disco duro externo. Todo ello probado y funcionando al mismo tiempo. A veces con un portátil también. Sigo muy satisfecho con el producto.
