Because the power failure, the company's financial department to buy two Hills 500i UPS
Do you need to turn off the UPS after work? The
Thank you
Also after the power outage, the computer and other equipment is turned off, need to shut down the UPS?
UPS backup power supply.
Is required to be closed.
The effect of the UPS is that after a power outage, there is a short power supply time that allows the user to store data and safely shut down the computer.
If you do not turn off the UPS. If the power outage at night will consume UPS power.
The next day to work and then open.
UPS does not need to be closed every day.
UPS uninterruptible power supply works as follows:
AC-DC conversion: the grid to the AC power by the autotransformer step-down, full-wave rectifier, filter into a DC voltage, the inverter circuit.
DC-AC inverter circuit: the use of high-power IGBT module full-bridge inverter circuit, with a large power margin, the output dynamic range of the output impedance is particularly small, with fast response characteristics. Due to the use of high-frequency modulation current limiting technology, and fast short-circuit protection technology, so that the inverter regardless of the supply voltage transient or load impact or short circuit, can be safe and reliable work.
There are two kinds of UPS, one is open charging, the other is inserted can be charged.
If it is the former, then shut the computer when you can.
If it is the latter, and the computer together off the line.
Some other considerations:
?1) UPS use of the environment should pay attention to good ventilation, conducive to heat, and keep the environment clean.
?2) Do not carry emotional load, such as Dianchao Ji, fluorescent, air conditioning, etc., so as to avoid damage.
?3) UPS output load control in about 60% for the best, the highest reliability.
?4) UPS with light (such as 1000VA UPS with 100VA load) may cause the battery depth of discharge, will reduce the battery life, should be avoided.
?5) the appropriate discharge, contribute to the activation of the battery, such as long-term non-stop electricity, every three months should be cut off the mains with UPS with a load discharge time, this can extend the battery life.
?6) for most small UPS, work and then open the UPS, boot to avoid the boot start, get off work should be shut down UPS; UPS for the network room, because most of the network is 24 hours of work, so UPS must also run around the clock.
?7) UPS discharge should be promptly charged to avoid the battery due to excessive self-discharge and damage.
