Line Interactive UPSLine Interactive UPS 800w 1KVA with Battery Backup Power Supply System
Tips:
Higher Efficiency
View DetailsCompare the three displayed Techfine CYE UPS pages
Open the exact 1, 2 or 3 kVA table, resolve any title/table mismatch, then confirm topology, load, transfer, battery/runtime, controls, files, warranty and supply.
Displayed CYE routes
Separate the current 1, 2 and 3 kVA tables before comparing backup time
The three pages share many feature lines, but rating, battery arrangement, charger and source consistency still need model-level review.
CYE1K(S) table
The displayed table states 1000 VA/800 W, up to 8 ms transfer and a 24 V standard battery route using two 12 V/7 Ah units; confirm the full suffix, included batteries, outlets and current manual.
CYE2K(S) table
The source table states 2000 VA/1600 W and shows alternative standard battery quantities/DC voltages plus a long-run route. Freeze the exact battery configuration and charger before quoting runtime.
CYE3K(S) table
The parameter table states 3000 VA/2400 W with six standard 12 V/7 Ah batteries, while the page title says 6 kVA/4800 W. Request a corrected model sheet and nameplate evidence.
Standard, long-run and optional routes
Standard and long-run descriptions use different battery quantities, DC buses and charging currents; RS-232/USB and SNMP wording also varies between standard and optional scope.
Line-interactive UPS RFQ checks
Six checks before shortlisting a Techfine CYE UPS
A useful comparison starts with the protected load and required continuity, then fixes one exact UPS and battery configuration.
Load and continuity objective
List continuous W/VA, power factor, nonlinear crest demand, motor or compressor starts, medical/IT sensitivity, acceptable interruption and required autonomy at normal and peak load.
Topology, transfer and waveform
Confirm the exact line-interactive operating path, AVR/bypass behavior, transfer test conditions, pure-sine-wave output, voltage/frequency regulation and THD for the actual linear or nonlinear load.
AC and regional version
Confirm input range, output voltage/frequency, plug/outlet or terminal type, neutral/grounding, generator source characteristics, protection coordination and destination electrical evidence.
Battery and runtime
Fix standard or long-run suffix, battery chemistry/model, series quantity, DC voltage, Ah, charger current, cutoff, cabinet/cables and runtime curve at the stated W load and temperature.
Controls, alarm and bypass
Confirm display, audible alarms, RS-232/USB, optional SNMP, shutdown software/OS support, dry contacts if needed, bypass mode/rating and behavior after battery or internal failure.
Evidence and order scope
Request corrected datasheet/nameplate, manual, safety/EMC and surge evidence, battery files, warranty, included accessories and software; confirm quantity, sample, lead time and substitution control.
Rating and continuity boundaries
A UPS title, VA label or long-backup claim is not a runtime guarantee
Continuity depends on exact rating, load waveform, battery configuration, temperature, transfer path, protection and maintenance.
Resolve the 6 kVA versus 3 kVA conflict
Do not quote the third page from its headline alone. Its current table identifies CYE3K(S), 3000 VA/2400 W. Require a corrected, signed model document and matching nameplate.
W, VA and surge are different limits
An 0.8 W/VA ratio or 3:1 surge line does not approve every motor, transformer, PSU or medical load. Confirm crest factor, start current, duration, waveform and overload curve.
Up to 24 hours needs a declared load
Runtime changes with load, battery Ah/chemistry/age, DC losses, cutoff, charger, temperature and reserve. Quote autonomy only from an exact configuration and documented runtime basis.
Feature wording is not system approval
Lightning protection, generator compatibility, low leakage or B-ultrasound wording does not establish destination compliance or equipment compatibility without exact tests, installation and responsible approval.
Continue the UPS review
Connect the model shortlist to load priority and autonomy sizing
Use the backup solution to define protected circuits and the sizing guide to document load and battery assumptions.
Small-business backup solution
Use its critical-load method to separate essential IT, communications, refrigeration or service loads from equipment that need not sit behind the UPS.
Review load priorities
Backup and battery sizing guide
Document continuous and peak loads, usable energy, reserve, temperature and inverter limits before presenting an autonomy figure.

Techfine line-interactive UPS FAQ
Questions to close before fixing a CYE configuration
These answers organize procurement; final load compatibility, runtime and continuity remain exact-model and installation questions.
Is the third Techfine line-interactive UPS page 6 kVA or 3 kVA?
The displayed title says 6 kVA/4800 W, but its current parameter table says CYE3K(S), 3000 VA/2400 W. Treat the rating as unresolved until a corrected datasheet and matching nameplate are supplied.
Does the long-backup wording guarantee 24 hours?
No. Runtime requires an exact W load, battery chemistry, series quantity, DC voltage/Ah, cutoff, charger, temperature, age and reserve. Request a configuration-specific runtime table or calculation.
Can a line-interactive UPS protect any motor, server or medical device?
Do not assume so. Confirm continuous W/VA, power factor, crest and start demand, waveform/THD, transfer tolerance, leakage/EMC needs, grounding and the load manufacturer's requirements.
What should a Techfine CYE UPS RFQ include?
Include exact model/suffix, destination AC and outlets, protected loads and start demand, required transfer/autonomy, battery and charger, bypass/communications, evidence, quantity, sample and delivery target.

Techfine CYE Line-Interactive UPS Pages for Backup-Load RFQs
Compare three displayed CYE source pages whose current parameter tables describe 1000 VA/800 W, 2000 VA/1600 W and 3000 VA/2400 W single-phase routes. The third page title says 6 kVA/4800 W while its table says CYE3K(S), 3000 VA/2400 W; treat that as an unresolved source conflict, not a specification. Preserve the exact model and standard or long-run suffix, then confirm topology, continuous W and VA, load type and crest/start demand, input/output, transfer and bypass behavior, waveform/THD, battery quantity and DC bus, charger, autonomy calculation, communications, options, safety/EMC evidence, warranty and current supply terms.
