Electrical & Performance

Parameter Value
Rated Capacity 3,000 VA / 2,700 W
Input Nominal Voltage Options 110 / 115 / 120 / 127 VAC OR 208 / 220 / 230 / 240 VAC (depending on your region/model)
Input Voltage Range • At ~50% load: ~110-300 VAC
• At 100% load: ~176-300 VAC (for higher nominal settings), or equivalently narrower depending on lower nominal settings.
Input Frequency Range 40 Hz to 70 Hz
Input Power Factor ≥ 0.99 at full load nominal voltage
Output Value
Output Voltage Same as nominal setting: e.g. 208/220/230/240 VAC or other as set per unit.
Voltage Regulation ±1% when in battery mode.
Output Frequency • In line mode (synchronized): ~47-53 Hz or ~57-63 Hz depending on region.
• Battery mode: 50 Hz or 60 Hz ±0.5% or ±0.1 Hz depending on exact variant.
Waveform (Battery Mode) Pure sine wave
Crest Factor 3:1
Harmonic Distortion (THD) • ≤ ~3% for linear loads
• ≤ ~5‐6% for non-linear loads

Efficiency & Transfer

Mode Efficiency
AC (mains) mode ~ 90% ‒ around that (the chart shows AC mode efficiency rising with capacity; for 3kVA it’s higher than 1‐2kVA)
Battery mode Slightly lower, in the mid/high 80% range depending on load and battery configuration
  • Transfer Time (from AC mains → battery): essentially zero milliseconds (because it’s online/double conversion)

  • Transfer for Inverter ↔ Bypass: ~ 4 ms typical

Battery & Charging

Parameter Value
Standard Battery Type 12 V, 9 Ah sealed lead-acid (Valve Regulated Lead Acid, VRLA) batteries
Number of Batteries Standard model uses 4 batteries (12 V / 9 Ah each) to achieve the required DC bus voltage.
Charging Current (Max) Adjustable; values up to 4 A in some configurations for the 3 kVA model.
Recharge Time Approx ~4 hours to recover to 90% capacity in standard model under nominal conditions.

There is also a “Long-run” model variant (if fitted with more batteries / external battery packs) which changes battery count and charging current.

Mechanical / Physical

Parameter Value
Dimensions (UPS unit) ~ 630 × 438 × 88 mm (Depth × Width × Height), 3U form factor in many configurations.
Weight (UPS unit only) ~ 19 kg
Battery Pack (if external / long-run variant) Larger/heavier; for example external battery pack weight ~ 51 kg in some specs.

Environment & Other Features

Feature Specification
Operating Temperature Range 0-40 °C typical
Humidity 20-90 % RH non-condensing
Noise Level < ~58 dB at 1 meter for the 3 kVA model in many cases; standard model is “less than 50-55 dB” depending on battery/internals.
Display / Indicators LCD showing load, battery level, AC mode / battery mode / bypass mode / faults; LED indicators; audible alarms for battery low, overload, fault, etc.
Communications USB, RS-232; optional SNMP card / intelligent slot for network/web based monitoring.

Protections & Misc Features

  • Input Power Factor Correction (PFC) to reduce input current distortion.

  • ECO mode for energy saving (when mains input is stable) is available in 1-3 kVA models including 3kVA.

  • Generator compatibility — can be used with generator input, assuming the generator produces stable sine wave and meets input voltage/frequency requirements.

  • Overload behaviour: the unit will transfer to bypass or shutdown under overload depending on how much and how long. Battery low / over temp / short circuit protections built-in.
