Pure sinewave 1100VA UPS with critical load banking for smarter backup

The WattBox WB-UPS-1100-8 is an 8-outlet 1100VA UPS (900W max) designed to protect critical AV, IT, and networking equipment with clean, stable pure sinewave backup power. It is a strong choice for racks and workstations where you want voltage stability every day, plus enough runtime during outages to safely shut down or switch to generator power.

Why it fits AV, networking, and IT setups

• Pure sinewave output: Cleaner backup power for sensitive electronics and modern power supplies.
• 1100VA capacity (900W max): Solid headroom for typical rack and network stacks.
• Automatic Voltage Regulation (AVR): Stabilizes voltage without always switching to battery, helping extend battery life.
• Critical load bank: 4-outlet prioritized group helps keep the most important gear online longer.
• USB graceful shutdown: Supports automatic safe shutdown for PCs to reduce data loss risk.
• LCD status display: Quick visibility into battery, voltage, and load at a glance.
• EMI/RFI noise filtering: Helps reduce line noise that can affect AV and network stability.
• User-replaceable batteries: Extends product lifespan and simplifies maintenance.

Runtime reference

• Up to 3 minutes at full load
• Up to 9 minutes at half load

1. What should I plug into this UPS?
   Use it for essentials like modem, router, Wi Fi, network switch, NVR, and a streaming box. Avoid high-draw devices like large amps, heaters, and laser printers.
   
2. How long will it run during an outage?
   Runtime depends on load. A light network setup can run much longer than a fully loaded UPS. Keep only critical gear on battery to maximize runtime.
   
3. Does it support safe shutdown for a PC?
   Many UPS models support USB shutdown. If you plan to protect a PC or server, connect the USB cable and enable shutdown in your OS for cleaner power-off.
