| Topology | True Online / Double-Conversion (Rackmount or Tower format) |
| Phase | Single phase with ground |
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.
