An “ITA series” quotation is incomplete unless it identifies the generation, kVA rating, input/output phase arrangement, battery version and exact model code. You will be able to compare capacity, wiring, battery autonomy, installation conditions and supplier documentation before approving a 5 kVA, 6 kVA, 10 kVA or 20 kVA system.
Key takeaways
- Match the exact ITA2 model code to its kVA, kW and phase arrangement.
- Confirm input and output connections before sizing cables, breakers and isolators.
- Compare battery voltage, required autonomy and long-run battery cabinet arrangements.
- Request commissioning, service coverage and compliance documents in the quotation.
Match the ITA2 model, kVA, kW and phase arrangement
A comparison table is incomplete without the exact ITA2 model code, rated kVA, rated kW, output power factor, phase arrangement, battery version and overload rating. ITA and ITA2 ratings are not interchangeable.
kVA is apparent power; kW is the real power your equipment consumes. Output power factor links them: kW equals kVA multiplied by power factor. A unity-power-factor unit therefore has approximately equal kVA and kW capability. Older ITA variants or differently configured units may have lower power factor, so use the nameplate kW rating.
| Model code | Rated kVA | Rated kW | Output power factor | Recommended continuous load range | Overload duration | Battery version |
|---|---|---|---|---|---|---|
| ITA2 5 kVA, exact suffix required | 5 | 5 | 1.0 | Confirm manufacturer value | Confirm datasheet value | Confirm internal or external |
| ITA2 6 kVA, exact suffix required | 6 | 6 | 1.0 | Confirm manufacturer value | Confirm datasheet value | Confirm internal or external |
| ITA2 10 kVA 3x1, exact suffix required | 10 | 10 | 1.0 | Confirm manufacturer value | Confirm datasheet value | Confirm internal or external |
Do not add 1, 2, 3 or 20 kVA rows unless the quoted ITA2 datasheet confirms them. Usable load range is the continuous operating band, not the short overload limit.
The notation 1x1 means single-phase input and output; 3x1 means three-phase input and single-phase output; 3x3 means three-phase input and output. A 10 kVA 3x1 unit needs a three-phase supply even though its protected output is single-phase.
Require this detail from any single phase ups distributor in mumbai for ita series capacity specifications, including a single phase ups distributor in mumbai.
Specify the electrical connection before selecting cables and breakers
At 230 V single-phase, estimate full-load current as kVA × 1,000 ÷ 230: about 21.7 A at 5 kVA, 26.1 A at 6 kVA and 43.5 A at 10 kVA. These figures exclude charger demand, losses, voltage tolerance and design margin.
- Input and output voltage, input and output frequency, acceptable voltage and frequency windows
- Input power factor, input-current THD, crest-factor capability, overload duration and bypass-transfer conditions
- Manufacturer-specified input and output current, terminal-block or socket arrangement, conductor cross-section, upstream breaker, output isolator and short-circuit rating
2. Treat 5–10 kVA units as fixed-wired equipment, not domestic plug-in loads. Specify dedicated upstream protection, protective earth, isolation and separate maintenance-bypass connections.
Ask the supplier to size cables and breakers from the installation manual, not kVA alone; this is information every single phase ups dealers in mumbai and ups systems distributor in mumbai should provide.
A static bypass transfers electronically when defined voltage, frequency or overload conditions occur. A maintenance bypass lets you isolate the UPS safely while the load remains energised. Confirm whether neutral is solid-through or switched, where neutral-to-earth bonding is located, and how the bypass source is bonded.
Do not add a second downstream neutral-earth bond: it can create circulating current or nuisance residual-current trips.
Compare battery voltage, autonomy and long-run arrangements
Do not accept “up to 30 minutes” without the test conditions. Whether you contact single phase ups traders in mumbai or a single phase ups distributor in mumbai for ita series capacity specifications, require this information in the quotation:
- DC battery voltage, blocks per string, chemistry, Ah rating, number of strings, end-of-discharge voltage and recharge time after a defined discharge
- Autonomy at 25%, 50%, 75% and 100% load in kW, with the assumptions for battery age, temperature and string count
- Cabinet or rack inclusion, battery-cable details and responsibility for installation
Battery runtime follows load in kW, battery age, temperature, discharge limit and string capacity, not the UPS kVA rating alone. Ask for a runtime curve showing how minutes change as load falls.
| Battery arrangement | What to verify | Main risk |
|---|---|---|
| Standard-battery model | Internal battery set, included cabinet or rack, string count and recharge time | A quoted runtime excludes ageing or charger limits |
| Long-run model | External cabinet part number, charger arrangement and permitted string capacity | The UPS cannot support the proposed cabinet or runtime |
For the 1 kVA long-run model, obtain compatible cabinet part numbers, permitted battery voltage, maximum cable length, conductor size, polarity protection, DC isolator or fuse rating and installation method. Confirm whether recharge assumes one string, multiple strings or a specified battery temperature.
Put battery-room ventilation, access clearance and battery replacement responsibility in the purchase specification. A generic autonomy figure is not a comparable offer.
Check the UPS footprint, environment and compliance evidence
1. Before approving an ITA unit, require the exact generation and model datasheet to identify rack, tower or rack/tower-convertible installation, dimensions, net weight, front, rear and side clearances, ventilation direction, heat dissipation, fan-replacement access, operating and storage temperatures, relative humidity, maximum operating altitude and altitude derating.
Do not publish or approve dimensions, weights, noise figures or cooling assumptions from another ITA variant.
2. For a Mumbai server room without dedicated cooling, calculate heat load from the manufacturer’s UPS losses plus battery charging and float losses, then verify the room’s temperature control against that load. Keep air inlets unobstructed and do not place the UPS beside a heat source.
Obtain the measured or declared noise level and test condition before locating it near occupied work areas.
3. Request evidence to IEC 62040-1 safety, IEC 62040-2 electromagnetic compatibility and IEC 62040-3 performance and test requirements, plus BIS-adopted requirements named by the tender. Confirm generator compatibility, bypass-source voltage and frequency limits, short-circuit level and charger-start behaviour.
Treat parallel operation, N+1 redundancy and capacity expansion as separate features: the exact model, approved kit, control cabling, bypass arrangement, battery configuration and permitted unit count must support each one; two separately purchased units cannot be assumed to parallel safely.
Ask a single phase ups distributor in mumbai, single phase ups dealers in mumbai or ups systems distributor in mumbai for this model-specific evidence, not a generic CE or ISO statement.
Use a Mumbai supplier quotation that can be commissioned and serviced
Do not compare prices until every single phase UPS distributor in Mumbai, single phase UPS dealers in Mumbai, UPS systems distributor in Mumbai and single phase UPS traders in Mumbai quote an identical specification. Require the exact model code and generation, not a generic “ITA series” description.
| Item | Require in the quotation |
|---|---|
| Model and rating | Generation, kVA, output kW, phase arrangement, battery voltage, internal or external battery configuration, autonomy test load, bypass design and installation accessories |
| Design evidence | Signed single-line diagram, terminal schedule, cable and breaker requirements, earthing arrangement, battery-cabinet details, dimensions, clearances, heat output and noise data |
| Delivery and start-up | State whether delivery, unloading, installation, battery interconnection, start-up, load-bank testing, operator training and replaced-battery disposal are included |
| After-sales scope | Warranty boundaries, commissioning-test records, preventive-maintenance tasks and service-response process |
Ask for autonomy at named loads such as 25%, 50%, 75% and 100% kW, not one unqualified runtime. The supplier must identify who owns defects discovered during installation, battery connection and commissioning.
For parallel systems, demand the manufacturer-approved parallel kit, control cabling, permitted unit count, common or separate bypass design and battery arrangement. Two independently purchased UPS units cannot be assumed safe to parallel.
Originate Power Solutions belongs in the comparison only when it supplies this model-specific evidence and accepts responsibility for installation and commissioning. Compare documented scope, not the seller label or the lowest kVA-only price.
