Avoid making these mistakes when using a DC stabilized power supply
In electronic experiments, we often encounter DC stabilized power supplies, which can help us increase the success rate of experiments and provide accurate results. However, sometimes many novices make obvious mistakes when using them. Today, let's take a look at the precautions for using DC stabilized power supplies!
1. Voltage adjustment sequence
First adjust the "coarse adjustment" knob to a gear close to the target voltage.
Fine tune the "Fine Adjustment" knob to the desired precise voltage value.
2. Load access timing
After adjusting to the required voltage, connect the load to avoid damage to the equipment caused by sudden voltage changes.
3. Shift gear operation
Before changing the "coarse adjustment" gear, the load must be disconnected first.
After adjusting and confirming that the voltage is correct, connect the load again.
4. Fault handling
When encountering load short circuit or overload protection, disconnect the load first.
Press the 'Restore' button or restart the power supply, troubleshoot the issue, and then connect the load.
5. Serial usage restrictions
When multiple power sources are connected in series, the output current is limited to the one with the smallest rated value.
6. Header usage
Confirm that the header is in the correct A/V state, indicating current or voltage respectively.
7. Output terminal identification
The red terminal is the positive terminal (+), and the black terminal is the negative terminal (-).
The "earth" symbol terminal in the middle is only used for safety grounding and has no electrical connection with the output.
8. Voltage output mode
Two voltages can be used in series, but parallel connection is absolutely prohibited to prevent excessive current from damaging the power supply.
Avoid long-term short circuits at the output end to protect power equipment.
