One Delta UPS India standard for every rack and floor.
How a tier-2 diagnostic hospital stopped losing its lab analysers to power dips by sizing Delta Amplon and Ultron to the real load. Story below.
Delta UPS at a glance
Why Delta anchors most Indian ups estates.
- OEM
- Delta Electronics, a power-electronics maker that builds its own inverters, with a local arm in Delta Electronics India that manufactures and services inside the country. Sirius Star sizes, supplies, installs and services Delta UPS for Indian businesses from Vashi, Navi Mumbai.
- What it is
- A full UPS range from a desk unit to a multi-megawatt data-centre plant, in single-phase and three-phase, backed by cooling and power distribution from the same vendor.
- Why teams pick it
- Because Delta builds the power stage itself, the efficiency is measurable on the meter, not just on the brochure. On a large load, the gap between 92 and 96 percent shows up on the power bill every month.
- Core range
- Agilon line-interactive for desks and edge, Amplon single-phase online for server rooms, Ultron three-phase online for plant floors, and Modulon DPH modular for the data centre.
- Efficiency
- The Modulon DPH runs up to 96 percent in normal mode and up to 99 percent in ECO mode. The Amplon RT series holds up to 96.5 percent AC to AC. Higher efficiency means a lower bill and less heat.
- India reach
- Delta Electronics India manufactures locally and runs a service network across the country, so spares and engineers are not stuck in a customs queue for a buyer past the metros. Delta UPS is listed with authorised dealers on IndiaMART at Indian prices.
- Sirius Star role
- We study the load, size the right Delta line, calculate the runtime, deliver and commission, and stand behind the service. When APC, Vertiv or Eaton is the cleaner answer for your site, we tell you.

Delta Amplon single-phase online
The server-room workhorse. Online double-conversion holds the load behind clean inverter power, so there is no transfer beat when the DG takes over. Rack or tower.
- Online double-conversion, 1 to 20 kVA
- Up to 96.5 percent AC to AC efficiency
- Optional lithium-ion external battery cabinet
- From about INR 69,000 per unit*
Delta Ultron three-phase online
The proper three-phase room UPS. VFI double-conversion for plant floors and mid data centres, with parallel redundancy when one unit cannot carry the risk alone.
- Three-phase online, 20 kVA into the megawatt band
- Parallel redundancy for load-critical rooms
- Wide input window for a weak or DG grid
- Sized against your real load, not the nameplate
Delta Modulon DPH modular
Module-based architecture rated at 50 kW per power module. You add modules as the load grows, and a failed module hot-swaps without dropping the room.
- Hot-swap power modules with N+1 redundancy
- Up to 96 percent normal, up to 99 percent ECO
- Scales from one rack row to multi-megawatt
- Pay for capacity as the load actually grows
Delta Agilon and InfraSuite
Agilon line-interactive for a single PC, a billing counter or a small NVR. InfraSuite adds row and rack cooling, busway and rack PDU, so one vendor covers the whole white space.
- Line-interactive AVR for desk and edge loads
- Row and rack cooling from the same vendor
- Busway and metered rack PDU
- One matched design, one point of service
Delta UPS vs APC, Vertiv, Eaton
All four are honest choices. Most Indian buyers land on the first option for service depth and ecosystem fit.
| Brand | Where it wins | Best fit |
|---|---|---|
| Delta | Builds its own power electronics, so the efficiency is measurable on the meter. Strong three-phase and modular range, local India manufacturing, and cooling plus power distribution from one vendor. | Buyers who care about running cost and runtime, and who want one vendor for the UPS and the white space around it. |
| APC by Schneider | The default single-phase brand with a huge install base, mature PowerChute software and easy availability down to the smallest site. | Standard server rooms and small offices that want the most common brand and simple management. |
| Vertiv | Deep data-centre pedigree through the Liebert line, with heavyweight large three-phase systems and a wide service arm. | Large data centres that want a dedicated critical-power specialist across the whole facility. |
| Eaton | A broad range with good lithium options and strong distribution across small and mid loads. | Mixed estates that want one brand spanning desk units up to mid three-phase rooms. |

Delta UPS India FAQ
Common questions about this brand for Indian buyers. Hover any underlined term for a plain-English definition.
What are the Delta UPS families, and which one fits my load?
Delta covers four UPS families in India. Agilon is line-interactive for desks and edge loads up to about 3 kVA. Amplon is single-phase online double-conversion from 1 to 20 kVA for server rooms. Ultron is three-phase online from 20 kVA into the megawatt band for plant floors and mid data centres. Modulon DPH is a modular three-phase system rated at 50 kW per module that scales as the load grows. The right choice depends on your load, your phase and the runtime you need. Send Sirius Star the load and we return a sized quote in 24 working hours.
Is Delta UPS available and serviced across India?
Yes. Delta Electronics India manufactures locally and runs a service network across the country, so parts and engineers reach a site past the metros without waiting in a customs queue. Delta UPS models are listed with authorised dealers on IndiaMART at Indian prices, for example the Amplon RT 6 kVA rack UPS around INR 69,000. Sirius Star procures against that channel, commissions on site, and coordinates AMC and battery replacement through the Delta service network.
What does a Delta UPS cost in India in 2026?
An Amplon RT 6 kVA online rack UPS runs around INR 69,000*, and the RT 10 kVA around INR 1,07,500*, from authorised dealers. Small Agilon units cost less and three-phase Ultron and Modulon systems cost more, priced by capacity, battery runtime and redundancy. Delta does not publish a single public price list, so the honest number comes from a quote sized to your load. After the load study, Sirius Star returns a written quote in 24 working hours.
Which Delta line fits a server room, a plant and a data centre?
For a server room, the Amplon single-phase online range holds the load with no transfer beat when the DG takes over. For a plant floor or a mid data centre, the Ultron three-phase online range carries the bigger load with parallel redundancy. For a data centre that will grow, the Modulon DPH modular system lets you add power modules as the load rises and hot-swap a failed module without dropping the room. Sirius Star helps you match the line to the load and proves the runtime before handover.
What does Sirius Star do beyond supplying the UPS?
We do the work around the box. We study the load, size the right Delta line, calculate the runtime and the battery, deliver and commission on site, and prove the hold time before we hand over. We coordinate AMC, battery health checks and replacement through the Delta India service network, and we tell you when APC, Vertiv or Eaton is the cleaner answer for your site. The work runs from Vashi, Navi Mumbai, with a written 24 working hours quote SLA.
