Explanation of Common Functions of DC Power Supplies
DC power supplies are equipped with a variety of practical functions to ensure their stable and safe operation, meeting the power demand in different scenarios.
Protection Functions
Over-Voltage Protection (OVP)
When the output voltage exceeds the OVP set value, the output will be cut off. This control circuit can prevent damage or burnout of the load due to voltage surge. Its working modes vary by model and type, including input switch trip type and output termination type. In addition to power supply faults, OVP may also be triggered by external voltage or over-voltage input during external control.
Over-Current Protection (OCP)
For devices with OCP function, when the current reaches the OCP set value, the output current will be limited. Its working modes also include input switch trip type and output termination type. Besides the power supply's own faults, OCP may be activated by over-current input during external control.
Over-Heating Protection (OHP)
It monitors the heat release temperature of circuits that consume a lot of power (such as series voltage regulator circuits, switch circuits, and rectifier circuits). When the temperature exceeds a certain level, it will enter the protection mode like OVP and stop the output. A temperature fuse is installed inside the coil of the series voltage regulator. When the temperature exceeds a certain limit, the fuse will blow, and the output terminal will be automatically turned off.
Output Switch and Fuse Protection
When abnormal current occurs at the output terminal, it will be automatically cut off to prevent the expansion of faults.
Remote Sensing Monitoring Function
To reduce the impact of voltage drop caused by load line impedance, it applies a stable voltage to the load terminal, ensuring the accuracy of the voltage at the load end.
LOCK Function
This function can lock the operation interface of the power supply, preventing accidental changes to parameters such as voltage and current due to misoperation. It is very practical in experimental or work scenarios that require stable output parameters, ensuring the power supply continuously and stably supplies power to the equipment according to the set values.
MEMORY Function
It can store multiple sets of commonly used output parameter combinations such as voltage and current. When different output parameters are required for different equipment or different work stages, the stored parameters can be quickly called without repeated manual settings, improving operation efficiency. It is especially suitable for scenarios that require frequent switching of output parameters.
POWER Function
It mainly involves the on-off control of the power supply. Some power supplies also have a power status monitoring function, which can display the working status of the power supply, such as whether it is supplying power normally and which working mode it is in. This helps users understand the operation status of the power supply and detect abnormalities in a timely manner.
BATTERY Function
It is equipped with reverse polarity protection to prevent damage caused by reverse connection; it has over-charging protection, which automatically cuts off the power when the battery is fully charged. It optimizes charging efficiency and battery life.
