Operation altitude: 0

Lightning
Arresting Function
When the power supply system operates independently, input should bare
simulated lightning strike impact current waveform of 8/20
μ
S,
±
5 times
for impacts of 5KA amplitude, and the interval time of each testing
impacting is not less than 1min. If the power system is hit by a lightning
surge current even stronger than what is specified above, it will be
damaged and put out of function.
If higher lightning arresting class (Class C) is wanted, the outside
single-phase AC Class-C lightning arrester box (SPD23SZ or SPD25SZ
lightning arrester box produced in our company is recommended) is
needed at the input of the power system. With the outside lightning
arrester box, the input of the system should bare simulated lightning strike
voltage waveform of 10/700
μ
S,
±
5 times for impacts of 5KA, lightning
strike impact current waveform of 8/20
μ
S,
±
5 times for impacts of 20KA
amplitude, and the interval time of each testing impacting is not less than
1min. Also the lightning arrester box has auto-disengaged and recovery
protection function for input over-voltage (>295V
～
305V) to avoid the
system damage due to over-voltage.
