The voltage regulator is primarily designed for supplying power to low-voltage electrical appliances, typically featuring simple functions, high output power, and relatively high output current (ranging from a few to several dozen amperes), enabling power supply to multiple devices simultaneously. How is the adjustable DC voltage regulator/27V DC power supply applied?
Adjustable output voltage is a major feature of adjustable DC power supplies. Due to its adjustable voltage, it has a wide range of applications and is commonly used in laboratories and maintenance scenarios. For this reason, it is also known as "maintenance power supply" or "laboratory power supply." In fact, products used in laboratory and maintenance applications also offer other convenient and practical features, such as adjustable current limiting and tracking functions. The current limiting feature is particularly useful, allowing for the setting of high current outputs from the stabilized power supply.
When the output current exceeds the set value, the voltage drops, but the current no longer increases, as if the constant current mode has been engaged. Some power supplies offer overcurrent protection. When the current exceeds a certain threshold, it shifts to a protective state, shutting down the output and restarting the power supply to restore output. During experiments and maintenance work, short circuits may occur due to operational errors or circuit failures. By utilizing the current limiting function, not only is the safety of the power supply itself protected, but also the components in the circuit are shielded from the impact of high currents.
Generally, the current of voltage-regulated DC power supplies available in the general market is not large, with output currents ranging from 1 to 3A, which can meet the maintenance and testing needs of common digital products and mobile communication devices.
