Description

EVI Power 1000VA / 900W Rack Mount Online UPS

EVI Power 1000VA / 900W Rack Mount Online UPS is priced at Kes 29,500  here at Novelty Tech Solution in Nairobi, Kenya

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.
