Supply voltage Protection class standard lightning impulse breakdown voltage peaks at rated discharge current Isn, the residual voltage of the protected side, in terms of the power system arrester according to overvoltage category (1 Xifeng LED power supply factory outlets, 2 Xifeng LED Power Supply Price 3, 4), to determine their level of protection installed; for information systems in terms of protection LED power supply, the level of protection to be protected must match compatibility with systems and equipment. Power motor protection when the protected line phase line directly or through unintended load of earth is turned on, and produce non-sinusoidal waveform and its instantaneous change RMS residual current, when the current is greater than a certain value, the protector off the line .
