Offline UPSCompare the three displayed Techfine offline UPS pages
Open the exact 650, 1200 or 1500 VA table, resolve title/topology ambiguity, then confirm load compatibility, battery/runtime, outlets, files, warranty and supply.
Displayed offline UPS tables
Compare the 650, 1200 and 1500 VA records by exact table
The three tables share 220 V, modified-sine-wave and battery-protection wording, but their W rating, battery quantity and enclosure differ.
650 VA / 360 W table
The current table lists one 12 V/7.2 Ah battery, less-than-6 ms transfer and about six hours to 90% charge. The broader title also names 800–2000 VA, which are not established by this table.
1200 VA / 720 W table
This source page lists two 12 V/7.2 Ah batteries and the same modified-sine-wave output route. Confirm the exact model, battery inclusion, outlets and runtime curve.
1500 VA / 900 W table
The current table lists two 12 V/9 Ah batteries, although the page headline uses line-interactive wording. Require the exact topology/model document before classification or quotation.
Shared PC/office route
All three tables show 220 VAC, 50 Hz and offline transfer behavior. Do not infer a 110 V, 60 Hz, pure-sine, universal generator or other regional variant without exact evidence.
Offline UPS RFQ checks
Six checks before shortlisting an offline UPS
Start with the PC, monitor, network or office load and its tolerance for modified sine wave and transfer interruption.
Protected equipment and load
List every PC, monitor, router, POS or peripheral, normal/peak W and VA, PSU type/power factor, inrush and whether printers, motors, transformers or other sensitive loads are excluded.
Waveform and transfer tolerance
Confirm modified-sine-wave acceptance with the equipment supplier, plus transfer duration/test condition, voltage/frequency regulation, cold start and restart behavior.
AC, outlets and generator
Confirm destination voltage/frequency, plug/outlet count and type, grounding, input range, generator voltage/frequency/THD stability, protection coordination and regional evidence.
Battery and autonomy
Fix battery model, chemistry, quantity, Ah, inclusion, charger and recharge condition; request a runtime curve at the stated combined load rather than using VA as time.
Alarms, protection and service
Confirm LED/alarm behavior, overload and short-circuit handling, deep-discharge/overcharge protection, replaceable battery procedure, spares and service access.
Documents and supply
Request exact datasheet/nameplate, topology statement, manual, safety/EMC and battery evidence, warranty and accessories; confirm quantity, sample, lead time and substitutions.
Waveform and rating boundaries
Offline UPS and modified sine wave require load-specific approval
A PC-oriented title is not proof for every power supply, peripheral, motor or generator.
The table controls the current comparison
A title listing 650–2000 VA does not provide six verified configurations when the embedded table only specifies 650 VA. Freeze the exact table and model supplied.
Modified sine wave is not universal
Some active-PFC supplies, transformers, motors, audio or medical equipment may have additional waveform requirements. Obtain load-manufacturer acceptance and test the proposed combination.
Less than 6 ms is not zero interruption
Confirm whether the target device rides through the actual transfer event, including low battery, overload, cold start and return-to-mains behavior.
Generator-compatible wording is conditional
Generator size, voltage/frequency regulation, waveform THD, neutral/grounding and input-window behavior determine acceptance; a feature line is not a tested universal pairing.

Techfine offline UPS FAQ
Questions to close before selecting a PC or office UPS
These answers support procurement; the exact load, model table and regional version remain decisive.
Does the first page prove Techfine 650–2000 VA offline UPS specifications?
No. Its current embedded parameter table specifies a 650 VA/360 W unit. Request separate current tables and model identifiers for any 800, 1000, 1200, 1500 or 2000 VA quotation.
Will modified sine wave work with every PC and office device?
Do not assume so. Confirm the PSU, active-PFC, transformer, motor or peripheral requirements, normal/inrush demand and ride-through tolerance; test the exact combination where necessary.
Does less-than-6 ms transfer mean no interruption?
No. It is a source specification under unstated test detail, not zero transfer. Confirm the exact test condition and whether the target equipment remains operating through the event.
What should an offline UPS RFQ include?
Include exact model/table, destination AC and outlets, every protected load with W/VA/inrush, waveform acceptance, transfer/autonomy target, battery, generator details, evidence, quantity and schedule.

Techfine Offline UPS Pages for PC and Office Backup RFQs
Compare three current source pages whose parameter tables describe 650 VA/360 W, 1200 VA/720 W and 1500 VA/900 W, 220 VAC offline UPS routes with modified-sine-wave battery output and less-than-6 ms transfer wording. Some page headlines list broader 650–2000 VA families or call a 1500 VA item line-interactive, so category labels and titles must not replace the exact parameter table. Confirm the full model, real and apparent power, load PSU/motor compatibility, input/output and transfer behavior, battery quantity, runtime, charger, generator source, outlets, protection, safety/EMC evidence, warranty and current supply.
