Techfine 650 VA / 360 W Offline UPS Table Within a 650–2000 VA Source Title
The source title lists 650, 800, 1000, 1200, 1500 and 2000 VA, but the embedded parameter table specifies only a 650 VA/360 W offline UPS. That table describes 220 VAC input, 145–280 VAC mains range, modified-sine-wave battery output, less-than-6 ms transfer, one 12 V/7.2 Ah battery and six-hour charging to 90% under its stated condition. Separate current model sheets are required for every other rating named in the title.

Current document status
The current source record has one embedded 650 VA table and no downloadable model-specific datasheet. Request the full model code, nameplate and a separate current data sheet for each rating proposed in a quotation.
Current 650 VA table
Use the embedded 650 VA data only for the corresponding exact model
The broad source title does not create verified specifications for the other listed VA classes.
Displayed capacity
The embedded table states 650 VA/360 W. It does not show model-specific electrical or battery rows for 800, 1000, 1200, 1500 or 2000 VA.
Displayed AC behavior
The table shows 220 VAC, 145–280 VAC input range, 50 Hz battery output, ±10% battery-mode voltage and less-than-6 ms transfer. Confirm the regional version and test condition.
Modified-sine battery output
Load compatibility must be checked with the actual PSU, transformer, motor or peripheral; a PC-oriented title does not approve every office device.
Displayed battery
One 12 V/7.2 Ah battery and six hours to 90% charge are listed. Confirm included battery make/model, charger, cutoff, replacement route and runtime at the real combined load.
650 VA offline UPS RFQ checks
Six checks before selecting this record for PC or office backup
The final quotation must identify one exact model and the devices expected to ride through its transfer event.
Exact model and rating
Request the complete model code, nameplate, 650 VA/360 W confirmation and separate data for any alternate rating; prohibit silent substitution between title variants.
Protected equipment
List PC, monitor, router, POS and peripherals with normal/peak W and VA, active-PFC or transformer details, inrush and equipment excluded from the UPS.
Waveform acceptance
Confirm that each powered device accepts modified-sine-wave battery output and document any manufacturer requirement for pure sine wave or maximum transfer duration.
AC and outlets
Confirm destination voltage/frequency, plug and outlet count/type, grounding, input window, cold start, restart, return-to-mains behavior and local electrical evidence.
Battery and runtime
Confirm exact battery, Ah, inclusion, charger and cutoff; request runtime at the stated total W load and temperature rather than treating VA as operating time.
Generator, evidence and terms
Provide generator voltage/frequency/THD if used; request manual, safety/EMC evidence, warranty, accessories, sample, quantity, lead time and substitution control.
Range and load boundaries
A 650–2000 VA title does not establish six validated UPS models
Only the 650 VA table is currently visible, and even that table needs a complete model identity.
Do not extrapolate the range
Battery quantity, W rating, charger, size, outlets and transfer behavior for other VA classes must come from their own current model sheets.
Modified sine wave is not universal
Active-PFC supplies, transformers, motors, audio and medical equipment can have additional waveform requirements. Obtain load acceptance and test where needed.
Less than 6 ms is not zero transfer
Confirm whether every target device rides through the actual event, including low battery, overload, cold start and return-to-mains conditions.
Generator compatibility is conditional
Generator size, voltage/frequency regulation, waveform THD, neutral/grounding and the UPS input window determine whether the pairing operates correctly.

Questions created by the broad title and single parameter table
The answers prevent the 650 VA table from being copied across unverified models.
Does this page verify 650–2000 VA Techfine UPS models?
No. Its current embedded table specifies only 650 VA/360 W. Request separate current data sheets and exact model codes for any other VA rating.
Will the modified-sine output work with every PC?
Do not assume so. Confirm the PSU and active-PFC requirements, normal/inrush demand, waveform tolerance and transfer ride-through for every powered device.
Does less-than-6 ms mean no interruption?
No. It is a source value without full test detail, not zero transfer. Confirm the condition and test the target equipment where continuity matters.
What should be requested before ordering?
Obtain the exact model/nameplate, current datasheet/manual, output and outlet version, battery/charger/runtime data, waveform and transfer evidence, safety/EMC documents, warranty and terms.
Request an exact 650 VA offline UPS quotation
Send the protected devices, W/VA/inrush, waveform and transfer tolerance, destination AC/outlets, runtime target and generator details. Require an exact model sheet and nameplate.
