First, we introduce the protection characteristics of the varistor. The protection characteristics of the varistor are as the name implies.
When the value is not exceeded, the impact withstand voltage of the protected object cannot exceed our varistor.
The limit voltage.
The second one is the impact resistance. The so-called impact resistance is the already specified surge current and the varistor itself.
Relatively equal impact energy, there is one that is the average power that has been repeatedly impacted.
The third is about the life characteristics of varistor. There are two total varistor lifes. One is the continuous use of varistor.
For voltage life, the so-called continuous working life is the varistor under the specified ambient operating temperature and system voltage conditions can
One of the time of work, one is the impact life of the varistor, that is, the number of times the varistor can withstand the specified impact.
The fourth is that when the varistor is installed on the system, in addition to the protection of a "safety valve", there will be a
These additional related influences are what we often call "secondary effects." Here we need to consider the following three aspects, one is
The current capacity of the varistor itself; there is also a leakage current at the operating voltage of the system; the last one is the varistor
The nonlinear current of the device affects other circuits.
LED ceiling track light with CRI 90 shows the true color of the object and gets a vivid lighting experience that is suitable for art studio lighting. Modern lighting fixture's direction can 350° horizontal and 90° vertical rotation so that the LED lighting can be easy to install and use. Wall track lighting fixtures ceiling spotlight uses die cast aluminium material with great heat dissipation. We promise a 3-year warranty, no worry about using in commercial lighting.
