How much mA is the safe current as follows:
The amount of safe current depends on the specific application scenario and type of equipment. Below are some common application scenarios and corresponding safety current ranges, but please note that this is only a general recommendation and the specific safety current should be determined according to relevant industry standards and specifications.
A safe range of current for human contact:
1, Direct contact: According to the International Electrotechnical Commission (IEC) standards, the safe range of current for direct contact with the human body is 1-5mA. currents exceeding 5mA may be dangerous to the human body, while currents lower than 1mA are considered to be relatively safer.
2. Indirect contact: When the human body is connected to the power supply through a grounded or conductive object, the safe current range should be controlled below 10mA. More than 10mA current may cause human electric shock injury.
Second, the safe current range of electronic equipment:
1, low-voltage equipment: for household appliances, office equipment and other low-voltage equipment, the general requirements of the current does not exceed 10mA to ensure the safety of users. Standards and regulations may vary from country to country, so please follow local regulations and codes to determine the specific safe current range.
2. Medical equipment: Medical equipment has more stringent requirements for safe current, according to the relevant standards of the International Electrotechnical Commission (IEC), the safety current of medical equipment should not exceed 10μA (0.01mA).
Other special application scenarios:
1, automotive electrical system: the safety current standard in the automotive electrical system may vary from region to region, but usually the current range should be between several tens and hundreds of milliamperes.
2. Industrial equipment: The safe current range for industrial equipment may vary according to relevant industry standards and codes. When designing and using industrial equipment, it is necessary to consider the direct or indirect effects of current on the human body to ensure that the current is within an acceptable range.
In summary, the amount of safe current depends on the specific application scenario and type of equipment. To ensure personal safety and proper operation of the equipment, it is recommended to refer to relevant industry standards and codes to determine the appropriate safe current range.
