• Rated power (continuous): 1250 W • Overload power (instantaneous): 2000 VA • Battery voltage: 12 V • Rectifier (charging current): 20 A • Automatic mains voltage regulator - AVR: 170 - 270 VAC • No-load current (no load): 0.3 A ≤ No-load current ≤ 1.5 A • Acceptable range of supply voltage: Switching to battery supply takes place when the mains voltage is lower than 160 V (+ - 5 V) or higher than 260 V (+ - 5 V) • Mains frequency: 45 Hz ~ 65 Hz • UPS output voltage frequency: 50 Hz (+ - 0.5 Hz) • Range of output voltages: Voltage regulator AVR: 216 - 245 V, UPS - battery: 230 V (+ - 3%) • Overload protection (battery powered): In the event of an overload of 110% - 130%, the power is disconnected after 30 seconds. If the overload is higher than 130%, the power is disconnected immediately. • Overload protection (mains supply): The device gives an overload warning until the fuses trip. • Operating humidity: 10% RH ~ 90% RH • Permissible operating temperature: 0 ~ 40 ° C • Weight: 12 Kg
