What about KELONG UPS power without output?

Our God KELONG equipment protection UPS power output not how to do? When we are in urgent need of electricity transmission when it is not how to do it! Now Xiaobian to introduce some tips, I hope everyone can give in the emergency treatment equipment in convenience.
KELONG UPS power transmission is not how to do? If this is the case in daily life, I think everyone's first reaction is: This is not simple, for professional maintenance do not go! Yes, not what is professional personnel to solve things, but in this period was a waste of time. So, our own are always good, isn't it?
First, in the face of this situation, we should check the KELONG battery power line, to see if there is any problem, especially pay attention to check the current limiting resistor that together.
Two, if there is no problem, then we go to see if there is charred original electrical appliances, if there is, we have to be measured, replaced.
Three, assuming the above are no problem, at this point we are going to measure the AC output tube, we have to compare measurements to observe whether there is damage.
If, after the above three steps, we did not find any problems, we do not rush, we in the next step, that is we need to measure the pin voltage control module, and then to compare the fast voltage analysis.
KELONG UPS power, if there is no transmission, then these small skills are generally able to solve, and if it still can not solve it, you need to ask professional staff pull, I hope Xiaobian common sense to help you.
