An electronic device that provides a stable DC power supply to the load. The power supply of the DC stabilized power supply is mostly AC power. When the voltage or load resistance of the AC power supply changes, the DC output voltage of the regulator will remain stable. With the development of high-precision, high-stability and high-reliability of electronic equipment, DC stabilized power supply places high demands on the power supply of electronic equipment.
1. The output voltage value can be arbitrarily set and operated normally below the rated output voltage value.
2. The steady current value of the output current can be arbitrarily set and operated normally below the rated output current value.
3. The voltage regulation and steady current state of the DC stabilized power supply can be automatically converted and have corresponding status indications.
4. Accurate display and identification are required for the output voltage and current values.
5. For DC regulated power supplies with precise requirements on output voltage and current values, multi-turn potentiometers and voltage-current trimmer potentiometers or direct digital inputs are generally used.
6. Have a perfect protection circuit. The DC stabilized power supply should not be damaged when there is a short circuit or abnormal working state at the output end, and it can work normally immediately after the abnormal situation is eliminated.
Graphical description of the use of DC stabilized power supply1) Each power supply is used independently
The middle button is now in the eject position.
2) Positive and negative power connection
In this case, turn all the two CURRENT knobs to the right and put all the middle two selection buttons in the pop-up position.
