Key Specifications
| Parameter | Value |
|---|---|
| Capacity | 1,000 VA / 900 W |
| Phase | Single phase with ground |
| Input | Nominal voltage: selectable among 110 /115 /120 /127 VAC or 208 /220 /230 /240 VAC depending on region/model. |
| Input voltage range | – At ~50% load: wider range (e.g. 60-145 VAC or 120-300 VAC) EVI – At 100% load: narrower range (e.g. 90-145 VAC or 180-300 VAC) depending on nominal voltage setting. |
| Input frequency range | 40 Hz ‒ 70 Hz |
| Power Factor (Input) | ≥ 0.99 at nominal voltage, full load |
Output
| Parameter | Value |
|---|---|
| Output voltage | Matches the selected nominal setting (110 /115 /120 /127 or 208 /220 /230 /240 VAC) |
| Voltage regulation | ±1% in battery mode |
| Output frequency range | – Synchronized (line mode): ≈ 47-53 Hz or 57-63 Hz (depending on nominal) – Battery mode: approx. 50 Hz or 60 Hz ±0.5% (varies by model/region) |
| Waveform | Pure sine wave on battery mode |
| Crest factor | 3:1 |
| Harmonic distortion (THD) | ≤ ~3% for linear loads; ≤ ~6% for non-linear loads |
Transfer & Modes of Operation
-
Transfer time (AC → battery / battery → AC) is essentially zero for AC to battery (“online/DC-conversion” design), and 4 ms typical for inverter-to-bypass transfers.
-
Supports bypass mode, ECO mode, converter mode depending on configuration.
Efficiency
| Mode | Typical Efficiency |
|---|---|
| AC (on mains) mode | ~ 88-90% |
| Battery mode | ~ 83-90% depending on model and load |
Battery
| Attribute | Value |
|---|---|
| Battery type | 12 V, 9 Ah batteries (sealed lead-acid) in typical units around this rating. Number of batteries depends on model to achieve rated DC voltage. |
| Standard battery config | Often 2 batteries (in smaller model) for ~27.4 VDC nominal, in some models more for higher output voltages or long-run variants. |
| Recharge time | Approximately 4 hours to recover to about 90% capacity under nominal charging conditions. |
| Maximum charging current | Varies; some models allow adjustable charging current (1 A, 2 A, up to higher depending on battery count). |
Physical / Mechanical
-
Form-factor: Rackmount, usually 2U in height for the UPS unit itself.
-
Dimensions: ~ 310 × 438 × 88 mm (D × W × H) for the standard 1KR (1kVA rack) model.
-
Weight: Approximately 12 kg for the UPS unit (excluding external battery packs when applicable).
Environment & Other Features
-
Operating Temperature: 0-40 °C typical.
-
Humidity: 20-90 % RH non-condensing (often ~0-95 % for rack version).
-
Noise Level: ≤ ~50 dBA @ 1 m typically.
-
Management & Communication: USB, RS-232 ports for PC/host communications; LCD panel showing load, battery status, voltage etc. SNMP support or card slot in many models.
Protections & Limits
-
Overload protection: thresholds for % overload and time to shut-down vary. For example: at 105-110% load, at battery mode or during voltage fluctuations, shutdown or bypass within some minutes; more severe overloads get faster shutdown.
-
Excess input voltage (“high line”) and low input thresholds defined; automatic transfer to bypass when outside limits.
