直流稳压电源功能要求
Functional Requirements of DC Regulated Power Supply
1．输出电压值能够在额定输出电压值以下任意设定和正常工作。
1. Output voltage can be set and operated under rated output voltage.
2．输出电流的稳流值能在额定输出电流值以下任意设定和正常工作。
2. The steady current value of the output current can be set and operated arbitrarily below the rated output current value.
3．直流稳压电源的稳压与稳流状态能够自动转换并有相应的状态指示。
3. The steady-voltage and steady-current state of DC regulated power supply can be automatically changed and corresponding state indication is given.
4．对于输出的电压值和电流值要求精确的显示和识别。
4. Accurate display and identification of output voltage and current are required.
5．对于输出电压值和电流值有精准要求的直流稳压电源，一般要用多圈电位器和电压电流微调电位器，或者直接数字输入。
5. For DC regulated power supply with precise output voltage and current value, multi-loop potentiometer and voltage-current fine-tuning potentiometer or direct digital input are generally used.
6．要有完善的保护电路。直流稳压电源在输出端发生短路及异常工作状态时不应损坏，在异常情况消除后能立即正常工作。
6. We should have perfect protection circuit. DC regulated power supply should not be damaged when short circuit and abnormal working state occur at the output, and can work normally immediately after the abnormal situation is eliminated.
