What is the cause of UPS uninterruptible power supply failure? In the process of daily handling UPS repair application, we have found that there are many UPS failures due to factors such as batteries, main electricity, use environments and methods, and have a fault of the UPS itself, if they can make these factors It is not found that it is not due to the failure caused by UPS, and the customer can solve the problem faster. UPS uninterruptible power supply failure is the most reasonable reason, the common faults of the UPS motherboard are important, unstable, not charging, can not use several markets, cranes, etc. When repairing UPS, you should first check the battery, followed by the motherboard circuit: When it is determined that the main board circuit is faulty, you should check the market power regulatory power supply circuit, and then check the inverter circuit.
If the UPS uninterruptible power supply fails, we should check if the battery powered line has a problem. Pay special attention to check the current limiting resistance; if there is no problem here, let's take a look at whether there is a charred electrical component, If there is a measurement replacement. Suppose there is no problem, at this time we have to measure the exchange output, we have to compare measurements, observe if there is damaged place.
UPS uninterruptible power supply FAQ 1, rear-columering UPS When the load is close to full load, the power supply is normal, and the battery fuse is fuck in the battery-powered battery fuse, and the battery fuse is blown, indicating that the battery supply is too large. 2, UPS uninterrupted After the power is turned on, there is no display on the panel, and the UPS does not work fault analysis: in the mains input, battery and main electricity detecting part and battery voltage detection circuit 3, there is a market time UPS output normal, without market speed buzzer Changming, no output fault analysis: the battery and inverter partial fault can be inspected: check the battery voltage, see if the battery is insufficient, if the battery is insufficient, then check the battery itself or the charging circuit fault. 4, can not use the main electricity: the inverter output is normal, and when the mains input, there is no output to encounter such a fault, the mains detection circuit should first be checked.
At 260V, the corresponding signal will be issued to the control circuit, cut off the mains input path, and make the UPS in the inverting state. If the detection circuit is normal, check the relay conversion circuit. UPS uninterruptible power supply Daily Maintenance Method (1) Region to place UPS must have good ventilation, away from water, combustible gases and corrosive agents; should not be measured, keep the front panel to enter the wind hole rear cover fan outlet and box The surface of the wind is smooth; (2) check the cleanliness of the battery, the pole state, the outer casing or overheating traces of the battery, and the connection joint is strong, preventing the temperature change during the battery charge and discharge process.
Or too large contact resistance; (3) Pay attention to the load and characteristics of the UPS, the rated power of the device determines the size of the load, in order to ensure the service life of the UPS uninterruptible power supply, do not run in a full load in the full load, different The species requirements are different; (4) Strictly use the correct boot and shutdown operation procedures, it is strictly forbidden to automatically turn on and close the UPS power supply, and the overload use is prohibited. When the battery is used to protect the shutdown, it must be charged again. Can't boot directly.
The UPS uninterrupted power supply is a uninterruptible power supply containing the energy storage device, which is capable of protecting its soft, hardware during the operation of the device, and protects the device when the voltage is too high or too low. The uninterruptible power supply of the UPS is an important device for protecting power. Maintenance is an important task in the process of use, which can prevent machine failure.
