1) When the audio system does not turn on the equipment in the normal order, the system may amplify the introduced noise signal at the moment of power-on, resulting in a strong whistling sound, which may damage the power amplifier or the speaker in severe cases；

     2) When a large number of electrical equipment is powered on at the same time, due to the superposition effect of the current, a strong instantaneous surge current will be generated, which will seriously threaten the safety of the electrical equipment, and may damage the electrical equipment in serious cases.

 8) It is applied to centralized power management and control of electrical equipment, and its standard cabinet installation features are more suitable for unified management of the power supply of equipment in the cabinet.。

 1) Two working modes: sequential mode + pure pass-through mode, the working mode can be switched through the pass-through lock switch;

 2) 2-channel straight-through output + 8-channel timing output;

 3) The timing switch can control the 8-channel timing output power supply to be turned on and off in sequence, and the timing interval of each channel is 1 second;

 4) 8 single-control buttons, which can manually control the opening and closing of each sequential output power supply;

 5) Digital voltmeter, which can monitor the field voltage changes in real time;

 6) The carrying power of each channel is 2KW, and the maximum carrying power of the whole machine is 13KW;

 7) 10 universal power output sockets made of phosphor bronze;
