Smart FAQs

How long will the QHM‑660 run my router?

Runtime depends on the router’s power draw. Typical routers (6–15 W) can run for several hours; high‑power modems and DVRs will reduce backup time. For combined loads, expect 1–3 hours depending on devices.

Can I use this UPS with a DVR or NVR for CCTV?

Yes — the QHM‑660 is designed for small DVR/NVR units and cameras. Ensure the total connected load does not exceed the UPS rated capacity (660 VA / 360 W).

Is the battery user‑replaceable?

The unit uses a sealed lead‑acid battery that is serviceable by qualified technicians. Vlebazaar can assist with battery replacement and warranty guidance.

Will this UPS protect against power surges?

Yes — the QHM‑660 includes surge‑protected outlets to safeguard connected devices from spikes. For high‑risk areas, consider additional surge protection at the mains.

How noisy is the UPS during operation?

The QHM‑660 operates quietly with only occasional fan or alarm sounds under heavy load or fault conditions — suitable for home and office environments.

What warranty and support are included?

The UPS carries a 12‑month manufacturer warranty (and 6 months for the battery) as specified in the package. Vlebazaar provides assistance with warranty claims and technical support.

Can I connect my set‑top box and router together?

Yes. Use the battery‑backup sockets for critical devices (router, ONT) and the surge‑only sockets for non‑essential peripherals to maximize backup duration.
