recautions for the use of DC regulated power supply
1. According to the required voltage, first adjust the "coarse adjustment" knob, and then gradually adjust the "fine adjustment" knob to achieve correct coordination.
For example, when you need to output 12V voltage, you need to set the "coarse adjustment" knob to 15V, and then adjust the "fine adjustment" knob to 12V, and the "coarse" knob should not be set to 10V. Otherwise, the maximum output voltage cannot reach 12V.
2. After adjusting to the required voltage, connect the load.
3. During use, if you need to change the "coarse adjustment" gear, you should disconnect the load first, and then connect the load after the output voltage is adjusted to the required value.
4. During use, when the protection is caused by load short-circuit or overload, the load should be disconnected first, and then the "recovery" button should be pressed, or the power supply can be turned on again, and the voltage will resume normal operation. load.
5. When each power supply with different rated currents is used in series, the output current is the rated value of the one with the smallest rated value.
6. Each power supply has a meter, which indicates the output current or output voltage of this circuit when A/V is in different states. Usually placed in the voltage indicating state.
7. Each channel has two output terminals, red and black. The red terminal means "+", and the black terminal means "-". There is a black terminal connected to the "earth" symbol in the middle of the panel, which means that the terminal is connected to the chassis and is the same as each other. One output has no electrical connection and is only used as a safety line. Some people often take it for granted that the "earth" symbol indicates grounding, and "+" and "-" indicate that the positive and negative power supply outputs are used to supply power to the dual-power op amp.
8. Two voltages can be used in series. Parallel use is absolutely not allowed. The power supply is a supply instrument, so long-term short-circuiting of the output is not allowed.
