IEC 62368-1 Classification and limits of electrical energy sources - 能量源分类和限制
对于任何达到电压限制的电压，电流没有限制。同样，对于任何达到电流限制的电流，电压也没有限制，见上图。
For any voltage up to the voltage limit, there is no limit for the current. Likewise for any current up to the current limit, there is no limit for the voltage, see Figure above.

ES1
ES1是具有电流或电压等级的1类电能源
ot exceeding ES1 limits under
• normal operating conditions, and
• abnormal operating conditions, and
• single fault conditions of a component, device or insulation not serving as a safeguard; and
– not exceeding ES2 limits under single fault conditions of a basic safeguard or of a supplementary safeguard.
不超过ES1能量源限制
•正常操作条件，以及
•异常操作条件，以及
•不起保护作用的部件、装置或绝缘的单一故障条件；和
–在基本保障或补充保障的单一故障条件下，不超过ES2限值。

ES2
ES2是具有2类电能源，其中
– both the voltage and the current exceed the limits for ES1 ; and
– under
• normal operating conditions, and
• abnormal operating conditions, and
• single fault conditions,
either the voltage or the current does not exceed the limit for ES2.

ES2是2类电能源，其中：
–电压和电流均超过ES1的限值；和
–低于
•正常操作条件，以及
•异常操作条件，以及
•单一故障条件，
电压或电流不超过ES2的限制。

ES3
ES3 is a class 3 electrical energy source where both the voltage and current exceed the limit for ES2.
ES3是一种3级电源，电压和电流均超过ES2的限制。
