UPS Systems Dealers Mumbai ita2 Long Run Specifications and Battery Conditions

A long-run UPS quotation is incomplete when it gives only kVA and backup minutes. You need to verify the exact ITA2 configuration, watt capacity, battery-string design, runtime assumptions, installation requirements and acceptance tests before comparing offers from Mumbai suppliers.

Key takeaways

Verify the exact ITA2 order code against the manufacturer’s datasheet.
Compare measured running watts and startup current with usable UPS capacity.
Match battery strings to the UPS DC bus before calculating autonomy.
Require installation controls, battery condition records and acceptance terms.

Confirm the ITA2 model, usable watt capacity and electrical fit

A 1 kVA, 2 kVA or 3 kVA label does not prove that the UPS suits your load. Confirm the exact ITA2 order code against the manufacturer’s datasheet, then compare your measured running watts and startup current with the UPS’s usable watt rating.

A 3 kVA unit rated at 2.7 kW is not a 3 kW supply.

Quoted size	Published usable output	Basic sizing check
1 kVA	900 W	Keep measured demand below 900 W
2 kVA	1,800 W	Keep measured demand below 1,800 W
3 kVA	2,700 W	Keep measured demand below 2,700 W

Ask UPS systems dealers in Mumbai for ITA2 long-run specifications, not only a “long backup” description. Before accepting the offer, confirm:

The exact ITA2 order code and whether the package includes internal batteries, an external cabinet or rack, DC protection, cables and a commissioned battery string.
Input voltage range, output voltage, frequency, bypass arrangement, frequency-conversion mode and waveform.
Earthing and neutral treatment, upstream breaker type, available short-circuit current and compatibility with high-inrush equipment.
Your connected watts at normal and peak load, rather than VA alone; include servers, motors, printers and other devices that start suddenly.
Battery make, model, date code, string arrangement and warranty boundaries, because a nominally correct UPS can still be an unsuitable installation.

Require a complete technical specification instead of a long-run label

A long-run label is not a specification. Require the quotation to identify the exact ITA2 order code and provide these electrical and performance fields:

Field	What the quotation must state	Why it matters
Input and output	Input-voltage range, output voltage, frequency, frequency-conversion capability, phase and waveform	A nominally suitable UPS can fail if site voltage or frequency falls outside its limits
Capacity and performance	Rated kVA and usable watts, output power factor, efficiency, transfer time, bypass arrangement and overload capacity at defined durations	Two 2 kVA units can support different loads and ride through overloads differently
Battery system	DC-bus voltage, 12 V blocks per string, total blocks, number of strings, Ah rating, chemistry, connector, charger current and supported external cabinet	The wrong series count can damage the UPS; extra strings need approved fusing, cables and charger capacity
Evidence and conditions	IEC 62040-1 safety, IEC 62040-2 EMC and IEC 62040-3 performance evidence, plus test conditions for any runtime claim	A generic CE or ISO certificate does not prove UPS performance

Ask an ups systems distributor in mumbai to itemise whether the price includes internal batteries, cabinet or rack, DC isolator, string fuses, cables and commissioning. Require the battery make, model, date code, cabinet dimensions, weight, warranty boundaries, replacement-battery price and service response time.

Reject “long backup” unless the offer gives runtime in minutes at 25%, 50%, 75% and 100% load, with connected watts, power factor, battery age and ambient temperature stated.

Match battery strings to the UPS DC bus and calculate real autonomy

A battery string is compatible only when its series count and nominal voltage match the ITA2 UPS DC bus. Ask single phase UPS dealers in Mumbai for the UPS battery voltage, allowable voltage range, required 12 V block count per string, connector type and approved external cabinet list.

A wrong series count can damage the DC stage.

For each quotation, verify these battery details:

Battery make, model, chemistry, Ah rating and date code
Blocks per string, number of parallel strings and total Ah
Manufacturer approval for parallel strings, including fuses, cable sizes and charger current
Cabinet dimensions, ventilation provisions and total loaded weight
Battery warranty, replacement interval and replacement-battery price

A runtime claim is incomplete without its test conditions. Nominal energy is bus voltage multiplied by Ah, but usable energy falls with inverter losses, discharge rate, end voltage, battery age and temperature. A 100 Ah VRLA battery rated at 10 hours is not equivalent to one rated at 20 hours.

Require a runtime table showing minutes at 25%, 50%, 75% and 100% of the connected watt load, with the power factor, end-of-discharge voltage, battery temperature and battery condition stated. Check whether the figures come from IEC 62040-3 performance testing or the manufacturer’s published discharge curves; a generic CE or ISO certificate does not validate autonomy.

Recalculate using actual watts, not the UPS kVA label. A battery room above the reference temperature, commonly 25 °C, will shorten real runtime and battery life.

Specify installation controls and battery health conditions

An external battery bank stays reliable only when the room, DC protection, charger and acceptance test are specified—not inferred from “long-run.” Keep the UPS and batteries in an air-conditioned room near the manufacturer’s reference temperature, commonly 25°C, and log room and battery temperature. Heat shortens VRLA life, so adding Ah does not repair poor cooling.

Record input-voltage range, output voltage and frequency, bypass arrangement, earthing, neutral treatment, upstream breaker, available short-circuit current and high-inrush loads.
Obtain input-current, breaker, cable and charger-current data for charging mode; output kVA alone cannot size the feeder.
Install the external cabinet or rack on a level, non-combustible surface with access clearances, protected DC fuse or breaker, covered terminals and correctly torqued connections.
Use insulated tools and battery-rated PPE, verify polarity before energising, and provide ventilation required by the battery manufacturer.

Before handover, require a documented commissioning check covering string voltage, polarity, charger current, cable heating, alarms, bypass operation and protective-device coordination. The quotation should identify the external cabinet or rack, DC interconnects and commissioned battery string, plus compliance evidence for IEC 62040-1 safety, IEC 62040-2 EMC and IEC 62040-3 performance.

Ask a single-phase UPS distributor in Mumbai to perform an autonomy test at the agreed kW load, recording battery voltage, current, ambient temperature and cutoff voltage. Acceptance must state the minimum runtime and whether it applies to new batteries or end-of-life performance.

Compare Mumbai dealer quotations using evidence and acceptance terms

A “long backup” price is not comparable until every dealer prices the same battery system and acceptance test. Ask UPS systems dealers in Mumbai for the exact ITA2 order code, then compare the quoted equipment line by line.

Originate Power Solutions, for example, should be asked to identify what is included rather than relying on the long-run label.

Require these items in writing:

UPS order code, input-current and charger data, feeder breaker, cable size, and IEC 62040-1, IEC 62040-2 and IEC 62040-3 evidence.
Battery make, model, chemistry, Ah rating, date code, blocks per string, number of strings, DC voltage, cabinet or rack dimensions, and shipping weight.
Internal batteries, external cabinet, rack, DC isolator, string fuses, cables, guarded terminals, earthing and commissioning: mark each as included, excluded or optional.
Warranty boundaries, battery replacement price, service response time, exclusions, and the load and temperature used for the runtime promise.

Quote feature	Evidence to compare	Acceptance term
Runtime	Minutes at 25%, 50%, 75% and 100% load, with wattage and temperature	Witness a discharge test at the agreed load
Compliance	Declaration or test report tied to the quoted model	Reject generic CE or ISO certificates alone
Installation	Survey covering voltage, neutral, earthing, bypass, inrush and short-circuit current	Approve only after written site-fit confirmation
Service	Named response window and battery replacement scope	Record escalation contact and remedy for missed terms

A UPS systems distributor in Mumbai that refuses these details has not supplied an equivalent offer; compare the missing fields as exclusions, not savings.
