Reliable Backup for Short, Frequent Outages

For many ONT, ONU, router and modem setups, the real problem isn’t long-duration outages, it’s the internet dropping every time there’s a short, frequent power cut. Even a brief interruption breaks home and small office connectivity, and most projects don’t need an oversized backup system to solve that. The NBS-MU26 is a compact 12V 3A mini UPS built for exactly this gap, switching to battery automatically with zero transfer time so devices stay online without a reboot.

A Compact 12V 3A Backup Solution

The NBS-MU26 is designed for low-to-medium power broadband devices such as ONT, ONU, router, modem and selected CPE equipment. Setup is plug and play: connect the 12V adapter to the input port, plug your device into the output port, and flip the switch. The case measures 112 x 70 x 60mm and weighs just 235g, light enough to deploy quickly behind a router or in a small equipment cabinet.

Backup Time for Short-Outage Protection

The 19.24Wh battery holds approximately 4 to 5 hours at a light 6W load, 2 to 3 hours at a 12W load, and 1 to 1.5 hours at 18W. It’s built for customers who need compact, short-duration backup rather than oversized power capacity.

  • ONT and ONU backup
  • Router and modem backup
  • Low-power CPE backup

What kind of devices is the NBS-MU26 suitable for?

Standard 12V low-to-medium power devices such as ONT, ONU, router, modem and selected low-power CPE equipment.

Approximately 2 to 3 hours at a 12W load, longer at lighter loads. Actual runtime depends on the connected device’s power consumption
