Principle and precautions of programmable DC power supply

Industry Information

Programmable DC power supply has two programming methods, one is active, the other is passive. The passive programming algorithm is to change the reaction resistance and the input resistance to change the output value. The active programming algorithm is to change the output value of the reference voltage and the current of the reference. Secondly, there is the programming speed of the power supply.

Take you through the seven important components of DC power

Industry Information

Rectifier module system: The power rectifier module is the module that converts alternating current into direct current, usually according to the size of the current. It can be used in parallel with multiple modules. The module itself has perfect protection functions, such as input overvoltage protection, output overvoltage protection, output current limiting protection and output short circuit protection.

Waveform characteristics of DC regulated power supply

Company News

In the DC voltage regulator circuit, the waveform of the output voltage is mainly manifested in two aspects: ripple and noise. Ripple refers to the periodic fluctuation of the output voltage, which is caused by the AC component of the power supply current. In the circuit, the magnitude of the ripple is related to the capacitance value of the capacitor filter and the load current. The smaller the capacitance value, the greater the load current and the greater the ripple. Noise refers to the output voltage of high-frequency random fluctuations, usually by the components of their own noise and power supply current in the high-frequency components caused. In the DC voltage regulator circuit, the size of the noise is related to the phase noise of the components and the quality of the power supply current.

Maintenance and use steps of high-power DC power supply

Company News

When we use a high-power DC power supply, we should pay attention to the polarity of the DC voltage. If we need to let him output a positive voltage, we must connect the '-' end of the electrical equipment to the '-' end of the terminal' to the positive voltage end. If you need to output a negative voltage, you only need to put the wiring method off and connect it. Before use, first measure whether the power supply is qualified to avoid damage to the equipment during use. In order to ensure the normal use of electrical equipment, it is necessary to test the regulated power supply to make it work stably and reliably.
