Introduction to the components and functions of Schneider apcups power supply

Analysis of common faults of apcups power supply:

There is mains power supply and UPS has mains power cut off alarm

Possible causes: mains input control trip - poor contact of input AC line - mains input voltage too high, too low or abnormal frequency. -The ups input control is on or the switch is damaged or the fuse is blown. -UPS internal power supply detection circuit failure.

Handling method: check the input control switch - check the input circuit - if the power supply is abnormal, do not handle or start the power supply of the generator. -Replace the damaged switch, switch or fuse. -Check ups power supply detection circuit.

When the power supply is normal, the ups output is normal. After the power supply is cut off, the load is also cut off

Possible cause: the battery is under voltage due to the low voltage of the mains supply. -The ups charger is damaged and the battery cannot be charged. -Battery aging damage - load overload, UPS bypass output - load not connected to UPS output - battery pack of long time delay model not connected or poor contact - inverter damage, UPS bypass output.

Treatment: when the mains voltage is normal, fully charge the battery - start the generator to charge the battery - add a voltage regulator at the ups input - check the charger - replace the battery - reduce the load - connect the load to the ups output. Check whether the battery pack is connected properly. -Check the inverter

What should be paid attention to in the transformation of APC UPS power room

No matter what kind of machine room you put, you have to consider the following factors. For example, how about the temperature and air humidity of the local environment, whether the noise of this kind of machine is great, whether the height and width of the machine room are easy to make the machine work smoothly, etc. The transformation of computer room is a tedious project. In order to make the space more perfect to accommodate the machine, we must consider carefully and comprehensively. Take the above points for example, in the reconstruction of computer room, the room space should not be too small, too large, too waste, too small will lead to the machine can not be good heat dissipation, so that the machine is damaged, the humidity of the space should not be too large, not too hot, so when selecting the room, we should try to choose a middle-level geographical location, too high will make the space temperature too high, too low It will be cold and humid, and prone to insect and mouse disasters. For some noisy equipment, sound insulation should be done well under necessary conditions when the machine room is rebuilt. In addition, we need to do some dust prevention and ash control, cost control and other work. So it is a tedious project to reconstruct the computer room.
