IT / ITES & data centres
SOHO & branch desks
One Numeric portfolio runs from a finance desk to a three-phase data centre. We size every step, and say so when another brand fits better.
Numeric UPS lines we resell across India
The Numeric catalog is wide. Most buyers need one of these four modules. We size the rest case by case.
Digital line-interactive, 600 VA to 2.2 kVA
The desk and small-rack workhorse. Sine-wave output. AVR rides the typical grid dip. One server, a switch, and an NVR ride out their ten minutes.
Single-phase online, 1 to 10 kVA
The proper server-room UPS. Online double-conversion keeps the load behind clean inverter power the whole time. No transfer beat. No glitch on DG handover.
Keor HP three-phase online, 100 to 800 kVA
VFI three-phase double-conversion for the data centre. Rated bands run 100 to 800 kVA. Built for a real three-phase load with parallel redundancy.
Keor MP modular three-phase
Module-based architecture with three-level IGBT inverters. Efficiency up to 96 percent. Footprint up to 43 percent smaller. Scalable to 1.2 MW with hot-swap modules and N+1.
Where Numeric earns its place on the floor
Deep India service footprint
Numeric is a Legrand brand with a service network that reaches well past the metros. For a branch bank in a tier-3 town, that local reach beats an imported alternative on response time. We have seen a Pune plant get a same-week swap where an import meant a two-week wait.
One portfolio, desk to data centre
Run a finance desk on a Digital unit and the plant data centre on a Keor MP. One brand. One AMC conversation. One vendor on the call. See our Enterprise UPS and Power India guide.

A single unprotected power event can corrupt a database mid-write or down a backup appliance. The hardware is cheap next to the recovery.
When APC, Vertiv or Eaton is the better call
Honest answer. Numeric does not win every quote. Two scenes where we route you elsewhere.
A single global standard across many countries
If your group standardises one UPS brand across several countries, a global platform like APC Smart-UPS can be the cleaner fit. The published APC Smart-UPS datasheets make the spec match easy.
A large modular data centre with matched cooling
For a forty-rack pod that wants modular UPS plus matched precision cooling, Vertiv Liebert is a strong answer. Eaton wins plenty of mid-size server rooms. We sell all three. Pick what fits the room.
Numeric wins where India service depth and a single desk-to-floor portfolio matter most.
Numeric online vs APC Smart-UPS SRT vs Vertiv Liebert GXT5
The single-phase online tier, 1 to 10 kVA, is the most common server-room buy.
| What matters | Numeric single-phase online | APC Smart-UPS SRT | Vertiv Liebert GXT5 |
|---|---|---|---|
| India service depth | Very deep, metros to tier-3 | Deep, dealer-led | Strong in metros |
| Best fit | Branch and plant server rooms | Multi-country estates | Rooms with Liebert cooling |
All three are sound online units. The deciding factor is usually service reach and whether matched cooling is in scope.
Indicative Numeric pricing in India
Starting bands to help you budget. The real number lands on the quote once we size the load.
| Numeric line | Typical size | Topology | Indicative band (ex-GST) | Best fit |
|---|---|---|---|---|
| Digital line-interactive | 600 VA to 2.2 kVA | Line-interactive | ₹3,500 to ₹22,000 | Desk, comms cupboard, single server |
| Single-phase online | 1 to 10 kVA | Online double-conversion | ₹18,000 to ₹2,40,000 | Server rooms, BFSI branches |
| Keor HP | 100 to 800 kVA | Three-phase online | ₹6,50,000 onwards | Data-centre floor, real three-phase load |
| Keor MP modular | Scalable to 1.2 MW | Modular three-phase | Project-quoted | Large rooms, hot-swap modules, N+1 |
| External battery bank | Runtime add-on | VRLA or lithium-ion | ₹15,000 onwards | Extended hold time on any online unit |
Indicative starting bands in INR, ex-GST. The final price moves with kVA rating, battery chemistry, and runtime target. GST at 18 percent applies. We firm the number on the quote.
VRLA or lithium on the online line
This decision moves the ten-year ledger.
Standard VRLA, sealed lead-acid
Three to five years of design life. In a hot Indian closet, plan to replace nearer the four-year mark. Cheaper up front. Heavier. Disposal is a regulated waste item we handle properly.
Lithium-ion battery option
Longer design life. It tolerates heat far better than VRLA. Lighter. Higher up-front cost, lower cost across ten years. Worth modelling when the room runs warm.
We run both options on the quote. The CFO usually picks lithium once the ten-year number is on the table. Refreshing desktops too? Ask about Dell business laptops and Lenovo workstations on the same PO.
Modelling VRLA against the lithium ten-year ledger? We will run both options on your quote so the CFO sees the real number.
Refreshing the floor along with the rack? Buying fifty or more laptops in the same cycle? Ask about Device-as-a-Service and put the hardware on one monthly line with laptop leasing for business. Securing the data on those machines is a separate talk through Secure Data Guard and our cloud solutions team.
Numeric questions buyers actually ask
Is Numeric a good UPS brand for an Indian server room?
Yes, for most rooms. Numeric is a Legrand brand and one of the most widely deployed UPS lines in India. The online tier from 1 to 10 kVA gives full double-conversion power. The deep India service network is the real edge outside the metros.
What is the difference between Digital line-interactive and the online Numeric units?
Line-interactive units use AVR to correct grid dips and switch to battery only when supply fails, which suits desks and small loads. Online units keep the load behind clean inverter power at all times. Server rooms should use the online tier.
Who services Numeric UPS units across India?
Service runs through the Numeric and Legrand authorized partner network, which reaches well past the metros. Sirius Star coordinates the ticket. Metro response is usually same-day. Tier-2 and tier-3 SLA depends on the local partner footprint, shared on the quote.
How long does a Numeric UPS battery last in India?
VRLA batteries typically last three to five years in India, and heat is the biggest factor. The lithium-ion option runs much longer and tolerates heat better. We log the install date and send a battery reminder before end-of-life.
How do you size a Numeric UPS for my load?
We start with a free load assessment. We add real wattage, not the nameplate, pulled from the server vendor datasheet such as a Dell PowerEdge server, an HPE ProLiant node, or the Cisco switch stack. Add fifteen percent headroom. Map runtime to your longest logged outage. The quote lands in eight hours.
Related Hardware brands we resell

P.S. The day the grid dropped for ninety seconds and the plant data centre never noticed, the manager messaged us. Not to complain. To ask what we had changed. Arre, nothing dramatic. The right Numeric unit, sized right, with the battery bank we argued for. The win was that nobody noticed.
Who is Numeric UPS India a good fit for in India?
Numeric UPS India works best for Indian businesses that already have established workflows around the related platforms, need DPDP-compliant data residency, and want a single accountable partner for deployment plus quarterly tuning. Sirius Star runs the entire lifecycle — scoping, deployment, training, and renewal — from a Navi Mumbai engineering team.
How long does Numeric UPS India deployment take?
A typical Numeric UPS India rollout in India takes 2-6 weeks from purchase order to production cutover, depending on scope. Sirius Star follows a phased plan: scoping call within 8 working hours of enquiry, design review within 5 days, deployment waves, then a 30-day stabilisation window before handing over to your team or our managed retainer.
