Precautions when using a DC stabilized power supply unit
1, according to the required voltage, first adjust the "coarse" knob, and then gradually adjust the "fine" knob, to achieve the correct cooperation. For example, if you need to output 12V, you need to set the "coarse" knob at 15V, and 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, adjusted to the required voltage, and then access the load.
3, in the process of application, if you need to change the "coarse" gear, you should first disconnect the load, until the output voltage to the required value, and then access the load.
4, in the application process, due to load short-circuit or overload caused by maintenance, should be the first to disconnect the load, and then press the "restore" button, you can also turn on the power supply from the beginning, the voltage can be restored to normal operation, to be troubleshooting and then access the load.
5, the extra current is not equal to the power supply in series, the output current for the extra value of the smallest extra value.
6, each power supply has a meter head, in different conditions of A/V, respectively, to indicate the output current or output voltage of the road. Generally placed in the voltage indication condition.
7, each road has red, black two output terminals, red terminal indicates "+", black terminal indicates "-", the center of the panel with a "earth" symbol of the black terminal, indicating that the Symbol of the black terminal, indicating that the terminal connected to the chassis, and each output has no electrical connection, only as a safety line to use. Often people take for granted that the "earth" symbol indicates grounding, "+" "-" indicates that the positive and negative two power outputs to the dual power op amp power supply. The two voltages can be connected in series.
8, the two voltages can be used in series. Absolutely do not allow parallel operation. Power supply is a kind of supply instrument, so it is not allowed to short-circuit the output for a long time.
