UPS uninterruptible power supply manufacturers introduce the cause of the UPS power indicator flashing. The UPS power supply occupies a large part of the market in the market, and each product has different characteristics from other products. This is also a market that meets a variety of customer needs.
However, in the process of using UPS for a long time, if we don't care about it, go to maintain it, it will be aging in the pressure of frequent work. When in use, the indicator of the UPS power supply has been flashing. What is the representative? How to deal with it? The reason for the blinking of the UPS power indicator 1.
In the main mode: a. Green 1 light flashes, see the zero-fire line of the mains input, the UPS power supply can still work in the mains mode, the mains input should be input Two lines. b.
Green 1 light flashes, and yellow 1 light is on, indicating that the voltage or frequency of the main electricity or generator exceeds the normal range, and the UPS power is operated in battery mode. c. The yellow 1 indicator flashes, indicating that the UPS power is not connected to the battery or the battery voltage is too low.
At this time, check whether the battery is connected, determine whether the connection is correct, then the battery pack failure or battery aging should be excluded or replaced. d. If the load exceeds more than 96%, the buzzer will be screened once, and the load should be reduced, and the useless device should be lowered or canceled.
2, in battery mode: in battery supply, battery loss, load / battery 2, yellow 1 light is on, the buzzer will gradually become a long-lasting state, the output will automatically cut off, the UPS power is automatically shut down. 3, exception mode: During the operation, the fault indicator is on, indicating that the UPS power supply is in an abnormal mode. At this time, the load should be broken, and the device will be first connected to other power supply lines, turn off the UPS power supply, and the fault phenomenon is automatically station maintenance personnel , Waiting for professional processing, no failure continues to power.
The common fault of the UPS power supply, the UPS output is normal when there is time, and the buzzer is long, no output. Second, the battery voltage is low, but the boot charging is more than ten hours, the battery voltage is still can't be. Third, the inverter power level pair of power amplifier transistors are damaged, after replacing the same type of transistor, the reason for running for a period of time and burning is too large, and the current is too large.
The fourth, in the case of accessing the mains, each time the UPS is opened, he will hear the repeated action sound repeatedly, the UPS panel battery voltage is too low, and the buzzer is long. The fifth, the UPS is turned on when the power supply is normal, the inverter works indicator flashes, the buzzer makes an intermittent call, and the UPS can only work in the inverter, and cannot be converted to the main state of the mains. The above is the reason why the UPS power indicator flashes.
The UPS power supply sets a prompt light blinking effect to inform the user, so that the user uses the UPS power supply correctly to continuously power for the electronic product.
