Basic functions of DC voltage stabilized power supply, precautions for power supply use
1. Basic functions of DC voltage stabilized power supply
1. The output voltage value can be set arbitrarily, and it can work normally when it is lower than the rated output voltage value.
2. The steady-state current value of the output current can be set arbitrarily, and it works normally when it is lower than the rated output current value.
3. The steady-state and steady-state current states of the DC power supply will be automatically converted, and there will be corresponding state displays.
4. The output voltage and current values must be displayed and identified accurately.
5. For DC power supplies that require accurate output voltage and current values, multi-turn potentiometers and potentiometers for fine-tuning voltage and current or direct digital input are usually used.
6. A complete protection circuit is required. Even if the output terminals are shorted and become abnormal, the regulated DC power supply should not be damaged. After the exception is resolved, it will function normally.
2. Precautions when using DC voltage stabilized power supply
1. First gradually adjust the "Coarse Adjustment" button according to the required tension, and then gradually adjust the "Fine Adjustment" button to ensure correct fit. For example, if you need to output a voltage of 12V, you must set the "coarse adjustment" button to 15V, and then set the "fine adjustment" button to 12V, otherwise it will not reach 12v, and the maximum output voltage will not reach 12V.
2. Set the desired voltage and then reconnect it to the load.
3. If you need to change the "coarse adjustment" gear during operation, you must first disconnect the load, set the output voltage to the desired value, and then connect the load.
4. If the load is short-circuited or overloaded during operation, please disconnect the load first, then press the "recovery" button or turn off the power and then turn it on again to restore the voltage to normal operation. Connect after troubleshooting the load.
5. When connecting power supply units with different nominal currents in series, the output current must correspond to the nominal value of the minimum nominal current.
6. Each power supply has a measuring head to display the output current or output voltage of the channel in different A/V states. Usually placed in the voltage indicating state.
7. Each channel has two output connectors, red and black. A red connection means "+", a black connection means "-", and a black connection with a black symbol "earth" in the center of the control panel indicates that connection. Connect to the enclosure, and connect to each socket. One output has no electrical connection and is only used as a safety wire. It's easy to understand that the symbol "ground" means ground, and the "+" and "-" represent the positive and negative output power to power the op amp at double the power.
8. Two voltages can be connected in series. Simultaneous use is prohibited. Since the power supply is a power supply device, the output terminals cannot be short-circuited for a long time.
