Linear Power Supply

A Linear power supply is a power supply that provides a stable DC voltage output. The input AC is rectified, filtered and stabilized by linear voltage regulation technology to obtain stable DC output voltage.

The main features of linear DC power supply are as follows:
1. Stability: Linear DC power supply has high stability and can provide stable output voltage, which is suitable for applications with high voltage stability requirements.
2. Low noise: The output voltage of the linear DC regulated power supply has a low noise level, which is suitable for applications with high noise requirements, such as precision measurement, laboratory, etc.
3. High accuracy: The output voltage accuracy of linear DC voltage regulator power supply is high, usually within 0.1%, which is suitable for applications with high voltage accuracy requirements.
4. Fast response speed: The output voltage regulation response speed of linear DC voltage regulator power supply is fast, and it can quickly respond to load changes, which is suitable for applications with high requirements for load changes.
5. High reliability: The circuit structure of the linear DC regulated power supply is relatively simple, and there is no complex switching power supply control circuit, so the reliability is high and the life is long.

Linear DC power supply is widely used in laboratory, industrial automation, communication, medical equipment and other fields. According to the different output voltage, linear DC voltage regulator can be divided into single channel, dual channel, multi-channel and other different types to meet the needs of different application scenarios. At the same time, the linear DC power supply can also provide different output current, power and other parameters according to the need to choose.

The method of using linear DC regulated power supply is as follows:
1. Confirm the input power supply: linear DC voltage regulator power supply usually needs to be connected to AC power supply, so first confirm the parameters of the input power supply, such as voltage, frequency, etc. Ensure that the input power supply matches the requirements of the power supply device.
2. Connect the output load: Connect the load devices (such as electronic devices and circuit boards) that need power to the output port of the linear DC power supply. Connections are usually made using plugs, sockets or cables.
3. Set output voltage: As required, set the required output voltage through the knob, button or digital control panel on the linear DC regulated power supply. The output voltage can be adjusted according to the requirements of the load equipment.
4. Turn on the power supply: Turn on the power switch of the linear DC voltage regulator. At this time, the power supply starts to work and outputs a stable DC voltage.
5. Monitor the output voltage: Use the voltage monitoring function of the voltmeter, oscilloscope or load device to monitor the output voltage of the linear DC voltage regulator power supply to ensure that the output voltage is stable within the set value range.
6. Adjust the output current: If you need to adjust the output current, you can adjust the current adjustment knob or button on the linear DC voltage regulator power supply. Be careful not to exceed the rated output current of the device.
7. After use, turn off the power switch of the linear DC voltage regulator and disconnect the output load.

Note:
- When using linear DC power supply, pay attention to the load current should not exceed the rated output current of the device, so as to avoid overload or damage to the device.
- When adjusting the output voltage or current, it should be adjusted gradually to avoid sudden changes that are too large, so as not to cause damage to the load equipment.
- During use, pay attention to the heat dissipation of the equipment to avoid overheating resulting in equipment performance degradation or failure.
- When connecting and disconnecting the load device, ensure that the power device and the load device are in a state of power failure to avoid electric shock or short circuit.

- If you need to use a linear DC regulated power supply for a long time, it is recommended to consult the user manual of the device before use to understand the working time and use restrictions of the device.
