Electricity Saving |
When the power supply is normal, it is in a sleep state with power consumption less than0.1%; when there is no power supply, its efficiency is more than 92% |
When the electricity supply is normal, it is in work, with its efficiency only 85%~90%,and about10% to 15%electrical energy is consumed |
Noise |
When the power supply is normal, it is in a sleep state with no noise; when there is no power supply, its noiseis less that 55dB |
UPS work noise usually does not exceed55 to 65dB |
Life |
Only when the power supply is normal, does the inverter work. The motor life is relatively long, usually more than 15 years |
UPS will continuously work as long as it is turned on, so its life is relatively short, usually5 to 8 years |
Load Adaptability |
Adapted to electrical and other inductive loads and a variety of hybrid electric load |
UPS adapts to capacitive and resistive load (computer load) |
