Online UPS for a Server Room, CCTV or Clinic in Delhi
Three real setups — server rack, CCTV/NVR and a clinic counter — sized properly, with runtime and install notes.
Quick answer
The three loads that most often justify an online UPS in Delhi are a small server/network rack, a CCTV/NVR system, and a clinic counter with sensitive equipment. Each needs zero transfer time so nothing reboots on a cut — a 1–2 kVA Microtek online UPS covers most, with an external battery bank added for real runtime.
When the load must never blink
These three loads share one thing: a momentary gap is not a nuisance, it is a failure. A server corrupts a write; an NVR drops the footage you needed; a patient monitor reboots mid-reading. A home inverter cannot close that gap, and even a line-interactive UPS has a few-millisecond switch. Online (double-conversion) gives zero transfer time, which is exactly what each of these needs.
What these setups have in common
- Small critical loads — usually 150 W to 1,200 W — so 1–3 kVA online UPS fits most.
- They need clean, zero-gap power far more than they need many hours of runtime.
- Internal batteries give minutes; an external VRLA bank buys the hour(s) you actually want.
- Single-phase supply is normal — Microtek's single-phase range (E²/MAX+/iMAXX) covers all three.
Setup 1: a small server / network rack
A tower or rack server, a switch, a router and an ONT typically total 350–600 W. After headroom that sits on a 1 kVA E² (800 W), or a 2 kVA if you run two servers or a NAS. On internal batteries you get a few minutes — enough for the server to shut down cleanly through its UPS software. If the business needs the rack to stay up through a longer cut, we add an external battery bank sized to that target. The win is no corrupted writes and no surprise reboots.
Setup 2: CCTV / NVR and cameras
An NVR, a PoE switch and a monitor for a typical small site draw roughly 80–200 W — the cameras themselves are usually powered over the PoE switch. That comfortably fits a 1 kVA online UPS, and because the load is small, a modest external battery bank can keep recording going for an hour or more during a cut — which is often when you most want the cameras live. An inverter's changeover can reboot the NVR and leave a gap in the footage; online power avoids that.
Setup 3: a clinic or diagnostic counter
A clinic billing PC, a patient monitor and a small analyser might total around 800–1,200 W, suiting a 2 kVA online UPS sized with runtime to ride out a typical outage. This protects only the sensitive, must-not-blink equipment; the fridge, lights and fans belong on a separate, larger inverter-and-battery setup, because powering all of that at online-grade is needlessly expensive. Our clinic power-backup guide explains that two-tier approach in detail.
| Use case | Typical load | Suggested unit | Runtime approach |
|---|---|---|---|
| Small server / network rack | ~350–600 W | 1 kVA E² (2 kVA if 2 servers) | Internal for shutdown; external bank to stay up |
| CCTV / NVR site | ~80–200 W | 1 kVA | Small external bank for an hour or more |
| Clinic / diagnostic counter | ~800–1,200 W | 2 kVA | External bank sized to ride out the cut |
Typical online UPS setups (single-phase)
Why not just a big inverter?
An inverter is the right, economical choice for endurance loads — a fridge, lights, fans, pumps — where a 10–20 ms changeover is harmless. It is the wrong choice for any of the three loads above, because that same gap reboots a server, drops NVR footage or glitches a monitor. The honest answer is usually both: an online UPS for the handful of devices that must not blink, and an ordinary inverter and battery for everything else.

Frequently Asked Questions
What size UPS do I need for a CCTV / NVR system?
A typical small site (NVR, PoE switch, monitor) draws ~80–200 W, which fits a 1 kVA online UPS. Cameras are usually powered from the PoE switch. Add a modest external battery bank if you want the recording to keep going for an hour or more during a cut.
Can one online UPS protect a whole clinic?
It can, but it is rarely the economical choice. Put only the sensitive, must-not-blink equipment (monitor, ECG, analyser, billing PC) on a small online UPS, and run the fridge, lights and fans on a separate, larger inverter and battery. That two-tier setup costs far less than sizing everything at online grade.
