Precautions when using DC regulated power supplies
1, according to the required voltage, first adjust the "coarse" knob, and then gradually adjust the "fine" knob, to achieve the correct fit. For example, if you need to output 12V, you need to set the "coarse" knob at 15V, then adjust the "fine" knob to set 12V, and the "coarse" knob should not be set at 10V. Otherwise, the maximum output voltage will not reach 12V. Otherwise, the maximum output voltage will not reach 12V.
2、Adjust to the required voltage, and then access the load.
3, in the process of use, if you need to change the "coarse" gear, you should first disconnect the load, and then access the load after the output voltage is adjusted to the desired value.
4, in the process of use, due to load short-circuit or overload caused by the protection, should first disconnect the load, and then press the "recovery" button, you can also re-open the power supply, the voltage can be restored to normal operation, to be eliminated after the fault and then access the load.
5, the rated current is not equal to the power supply used in series, the output current for which the rated value of the smallest all the way to the rated value.
6, each power supply has a meter head, in different states of A/V, respectively, to indicate the output current or output voltage of the road. Usually placed in the voltage indication state.
7, each road has red, black two output terminals, red terminal that "+", black terminal that "-", the panel with the middle of the "earth" symbol of the black terminal, that is the "earth" Symbol of the black terminal in the middle of the panel with the "earth" symbol, that the terminal connected to the chassis, and each output has no electrical connection, only as a safety line to use. Often people take it for granted that the "earth" symbol means ground, "+" "-" means that the positive and negative power outputs go to the dual power op amp power supply. The "earth" symbol means ground.
8, the two voltages can be used in series. Absolutely do not allow parallel use. Power supply is a kind of supply instrument, so it is not allowed to short-circuit the output for a long time.
