What is a programmable DC power supply?

Programmable DC power supply is a process in which instructions are compiled into the machine in accordance with the order of operation, so that the machine runs automatically in accordance with the instructions. What is the use of programmable DC power supply? A programmable DC power supply is still a power supply. As for program control, that is to say, the output of this power supply can be controlled by programming. Programmable DC power supply can generate stable high-power industrial frequency voltage and current signals with adjustable amplitude, frequency and phase angle. It is mainly used for the testing and verification of current, voltage, phase, frequency and power meters; it can also be used to verify the basic error, creep and sensitivity of standard power meters.

Our daily life is inseparable from programmable DC power supply. When choosing a DC power supply, there are many factors that need to be considered, and there are many parameters involved. It is precisely because of the numerous parameters that people often feel overwhelmed and do not know what to do. In order to help you choose a programmable DC power supply, let me introduce what factors you need to consider when choosing a programmable DC power supply.

Programmable rise time: This is an area that many test applications need to focus on, such as LED testing. The instantaneous current at startup may be much larger than the LED working current, and the work is stable, causing damage to the LED equipment.

In order to prevent the transient voltage overshoot spike damage during the startup process, the power rise time of the device under test can have a programmable DC power supply current conversion rate control function and a constant current priority setting to reduce the overshoot power supply voltage and current of the LED power supply.

Battery simulation function: To test the power circuit or equipment under actual conditions, a test source with battery characteristics can be used. For example, changing the internal resistance of the programmable DC power supply, so the voltage applied to the battery-powered device will fall within the range of the internal resistance of the battery. Programmable DC power supply and programmable output resistance, do not underestimate the programmable characteristic resistance, it can complete the simulation of battery internal resistance, power battery performance simulation is the key.
