Precautions for using DC stabilized power supply
1. According to the voltage that the equipment needs to operate, adjust the thickness adjustment knob to achieve correct and effective coordination. For example, if you want to output 12 volts, set the coarse adjustment knob to 15 volts, and then adjust the fine adjustment knob to 12 volts. The coarse adjustment knob setting must be higher than the required output voltage, otherwise, the maximum output The voltage will not reach the corresponding value.
2. After adjusting to the required voltage, connect the load again.
3. When using a DC regulated power supply, when it is necessary to change the "coarse adjustment" gear operation, be sure to disconnect the load first and adjust the output voltage to the required index before connecting to the load.
4. During use, when the protection is caused by a load short circuit or overload, the load should be disconnected first, and then the "Reset" button should be disconnected. Of course, the power can also be restarted, and the load can be connected after the fault is eliminated.
5. When all power supplies with different rated currents are used in series, the output current is the rating of the power supply with the lowest rating.
6. Each power supply has an ammeter that indicates the output current or output voltage of the circuit under different AC voltage states. Usually placed in the voltage indication state.
7. Each circuit has two output terminals, red and black. The red terminal device is positive, and the black terminal is negative. Of course, there is a black terminal in the middle of the panel that serves as a ground for protecting life and property.
8. These two voltages can be used in series. Parallel connections are absolutely not allowed. The power supply is a power instrument, so the output terminal is not allowed to be short-circuited for a long time.
