Pay attention to the switch to avoid internal injuries. For more information on power supply and battery, please call Mr. Jiao on your mobile phone
What, is there a mystery in the opening and closing operation of the power supply? I believe many friends will be surprised like this! Indeed, the power supply is very particular about the opening and closing operations of the power supply. We must strictly follow a certain sequence of operations, otherwise it is easy to cause internal injuries to the power supply, and in serious cases, it can damage the power supply. Under normal circumstances, the correct sequence for turning on the power supply is to first check whether the power polarity of the input terminal of the power supply is consistent with that of the mains power supply line, and then check whether the total power of the load connected to the output terminal of the power supply is within the range of the power supply. After the above conditions are met within the rated power, turn on the power switch on the power control cabinet to allow the mains to supply power to the battery pack inside. After a period of time, turn on the power switches of the load one by one, so as to ensure that the load The current will not cause excessive impact on the internal power supply circuit of the power supply, thus effectively ensuring that the power supply is not damaged internally. The correct sequence for turning off the power supply should be to first turn off the loads connected to the output of the power supply one by one, and then turn off the power switch on the power control cabinet. If the power supply is not used for a long time, you can consider connecting it to the mains socket. Unplug the power cable on the computer to avoid lightning strikes during thunderstorm seasons, which may cause lightning strikes.
Pay attention to switching to avoid impacts
Since the power supply contains electronic working circuits, the various electrical components that make up the working circuits have very limited power and cannot withstand the frequent impact of strong currents. If we change the power supply If the switching operation is frequent, then the electronic working circuit in the power supply will have cutting-edge current flowing frequently, and various electrical components will easily generate heat and affect the work of the electrical components under the constant impact of the cutting-edge current. Performance, in severe cases, it can break down or burn out electronic components, such as fuses, transistors, two-section tubes, etc., which are particularly vulnerable to damage under the impact of large currents. In this case, the probability of power supply failure will greatly increase. In order to improve the working efficiency and stability of the power supply, we must not ignore the switching operation of the power supply. The author recommends that after the power is turned off, wait at least a few minutes before turning it back on
