2、 Main technical parameters

Common knowledge of using DC power supply

1, DingBasic definitions of voltage mode and constant current mode

The so-called constant voltage mode refers to the working mode in which the current value of the load varies within the rated range, while the output voltage of the DC power supply remains stable, When the load changes and the output current changes, the output voltage remains at the set voltage value and remains unchanged.

The constant current mode refers to the working mode in which the resistance value of the DC load varies within the rated range, while the output current of the DC power supply remains stable, When the resistance value of the load changes and causes a change in the output voltage, the output current remains at the set current value and remains unchanged.

Having constant electricitypress/ The working mode state of a DC power supply in constant current mode should be determined based on the nature of the load. In general, when the load is loaded with rated voltage and the actual load current value is less than the set current value, the DC power supply operates in constant voltage mode; When the actual load current value is greater than the set current value, the DC power supply operates in constant current mode.

The states of constant voltage mode and constant current mode are complementary, that is, the DC power supply either operates in constant voltage mode or in constant current mode. Therefore, before operation, users should first set the required voltage or current value correctly based on the nature of the load and the resistance value of the load, and choose the usage mode that meets the load requirements.

2 Capacitive load application:

Because capacitive loads often cause an increase in output voltage, especially when adjusting the output voltage from high to low, it can lead to a slow decrease in output voltage. Therefore, when using themOutput of DC power supplyConnect a power resistor in parallel and connect it in series between the output and the loadDiode, canObtain better usability. (See the figure below)

3 Inductive load application

When switching on or off a DC power supply or changing the output voltage, inductive loads can generate reverse induced electromotive force, affecting the operation of the DC power supply and even causing damage to it. At this timeOutput of DC power supplyConnect one in series between the end and the loadA diode, and inThe load end is composed of a power resistor and a capacitor connected in parallelRCAbsorption circuit can effectively protect DC power supply.(See the figure below)

4 Battery load application

When a DC power supply is used to charge battery loads, in order to prevent damage to the power supply caused by misconnecting the polarity of the battery, a diode should be connected in series between the power supply and the battery to protect the safe use of the DC power supply.(See the figure below)

5、 Pulse type load application

The peak current of pulse type loads is within the rated output current range of the DC power supply, or the load current waveform of pulse type circuits or motor drive circuits is within the nominal value (average value) indicated by the measuring equipment. The current will also reach the rated current range of the DC power supply, causing the output voltage to drop or appear unstable. The solution is to connect an inductor in series between the power supply and the load, or choose a DC power supply with a larger output current.

If the pulse width of the pulse type circuit is narrow or the peak current is small, a large capacity capacitor can be installed at the load end to improve it ,Can be done according to1 Ampere approximately 1000UFSelect capacitors.(See the figure below)

6 canApplication of loads that generate reverse current

When the motor connected to the output terminal of the DC power supply suddenly brakes, a large reverse current will be generated. Due to the inability of the DC power supply to absorb the reverse current generated from the load terminal, the output voltage will rise. The solution is toOutput of DC power supplyConnect one in series between the end and the loadA diode is connected in parallel with a discharge resistor at the load end to absorb reverse current. When the reverse current is a sharp spike, please connect a large capacity electrolytic capacitor in parallel at both ends of the load.(See the figure below)

Our company's series of DC power suppliesCan meet the normal usage requirements of users with different types of loads such as resistive, capacitive, and inductive. However, due to the differences in the properties of resistive, capacitive, and inductive loads, corresponding measures still need to be taken for different load properties in specific applications in order to achieve the best usage effect!
