APC-ES500, the sound of electricity and beep. Just pick up a notebook and a cat, please. Is there any way to adjust his voltage range?. Loud discomfort.
You are very experienced, must be the city power input range exceeds the use of UPS, which led to UPS constantly in the city power and battery status switch back and forth, the relay does not stop sounding.The power input range of the APC UPS is adjustable, but the rated load will be lowered when the city power range is increased, but there is no problem with your notebook and cat. Adjust the input voltage range, the need to UPS and computer through the communication port (such as RS232) connection, use brand specific software for adjustment, this need you contact APC customer service personnel to deal with, they will help you.PS: brother, I just want to ask, why does your notebook have to be brought with UPS? Doesn't it have its own batteries?
Check the battery voltage, it is estimated that the UPS battery is not working. And you make sure the city power is normal See if the power line is connected
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, and so on.UPS (Uninterruptible, Power, System), that is, uninterruptible power supply, is a kind of energy storage device, inverter as the main component of constant voltage constant frequency uninterruptible power supply. 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.
UPS power is always ringing:1, UPS is in the battery power supply status, please check the power supply is normal.2, UPS in the battery power supply, the machine shows that the power supply time is 0, please check the battery voltage is normal.
