Precautions for use of DC plug mold

1. According to the required voltage, first adjust the "coarse adjustment" knob, and then gradually adjust the "fine adjustment" knob to achieve correct cooperation. 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 set 12V, and the "coarse adjustment" knob should not be set to 10V. Otherwise, the output voltage cannot reach 12V.

2. After adjusting to the required voltage, the DC plug mold is connected to the load.

   3. During operation, if the demand changes to "coarse adjustment", the load should be disconnected first, and then the load should be connected after the output voltage is adjusted to the required value.

4. During the operation, when the maintenance is caused by the short circuit or overload of the load, the load should be disconnected first, and then the "Rehabilitation" button can be pressed, and the power can be turned on again. The voltage can be restored to normal operation, and then connected after troubleshooting load.

  Five, when the power sources of different rated currents are used in series, the output current is the rated value of the smallest one among the rated values.

   6. Each DC plug mold has a meter head. When the A/V conditions are different, it indicates the output current or output voltage of this channel. Generally placed on the voltage indication condition.

7. Each DC plug mold has two red and black output terminals. The red terminal indicates "+", the black terminal indicates "-", and the black terminal connected to the "earth" symbol in the center of the panel indicates that the terminal is connected to the chassis. , There is no electrical connection with each output, only used as a safety line. It is often taken for granted that the "earth" symbol indicates grounding, and "+" and "-" indicate that the positive and negative power outputs are used to power dual-power op amps.

  Eight, two voltages can be used in series. Never allow parallel operation. The power supply is a supply quantity instrument, so it is not allowed to short-circuit the output for a long time.
