Home UPS power insurance burned, ready to change their own insurance, open a look, put the insurance of the plastic have been burned, so they put the insurance shock point line re connected, and replaced with new insurance. The UPS is inserted in the socket by pressing the switch socket UPS back with a pencil, two empty are charged, plug in the appliance does not work. But if you unplug the ups from the mains and plug the socket with the light onto the ups, the lights on the socket are still on. I do not know the electricity, I do not know, I do not understand, I hope that an expert to help answer the question is where, thank you
Poorly described or poorly judged.First of all, don't know your UPS brand and model, anyway, the most effective way is to find the seller, it can be solved.To write you a UPS troubleshooting instructions, "UPS uninterruptible power supply common faults and how to troubleshoot."
Have power output of UPS is normal, and no power when the buzzer ringing, no output.Fault analysis: judging from the phenomenon of the battery and inverter part of the fault, the following procedures can be checked:Check the battery voltage to see if the battery is charged enough. If the battery is not charged enough, check the battery itself or the charging circuit fault.If the battery operating voltage is normal, check whether the inverter drive circuit is working properly. If the output of the drive circuit is normal, the inverter is damaged.If the inverter drive circuit is not working properly, then check the waveform generation circuit, whether there is PWM control signal output, if there is a control signal output, indicating the fault in the inverter drive circuit.If the waveform generator circuit does not have the PWM control signal output, it will check whether the output is blocked due to the protection of the circuit. If so, the cause of the protection will be found out;If the protection circuit is not working and the working voltage is normal, and the waveform generating circuit has no PWM waveform output, the waveform generation circuit is damaged.The sequence can also be reversed, and sometimes faults can be detected more quickly.
The 2 hole refers to the zero fire flower, it is estimated that the short circuit, it is best not to use, and the general equipment inside the zero line is straight through, it can not be as you say are chargedAgain, I don't understand how you measure the live current. Specifically, what do you use and where do you wait?
