UPS power sounds, what's the matter?
The landlord's description is not clear enough.1, UPS itself in the work is, fans, inductors, transformers will have a sound, as long as it is not very sharp, it should be no problem.2, UPS work, as long as there are alarm (general time, major failures), etc., there will be a buzzer called. General corrosion Ming is a small fault (automatic recovery), is a large fault (recovery), anxious Ming long only a major fault.
UPS is an uninterruptible power supply, including an energy storage device and an uninterruptible power supply with constant frequency and constant frequency as the main component. Used primarily to provide uninterrupted power supply to a single computer, computer network system, or other power electronic equipment. When the power input is normal, UPS electric voltage supplied to the load, the UPS is an AC power regulator, it is also the built-in battery; when the power interruption (outage), UPS will immediately machine battery power through the inverter conversion method continue to supply 220V AC power to the load, the load to maintain normal working load and protection of software and hardware is not damaged. UPS devices usually provide protection against too large voltages and too low voltages.
The reasons are as follows:The machine itself has a certain noise, clean environment, maintenance of good noise points. If there is alarm, there are many cases, after the power failure, the battery power supply, voltage instability, resulting in battery power, as well as machine failure, there will be an alarm.
