Technical Data

Input Characteristics

Input Voltage Range: Typically capable of accommodating a wide range of input voltages, such as 100 - 240V AC input, and some models may also support a range of DC inputs. This wide range of input voltage adaptability makes it possible to work properly in different power grid environments, reducing the limitations of external power supplies.

Input Frequency Range: For AC input, it is able to adapt to the common frequency range of 50 - 60Hz, ensuring stable operation under different national and regional grid frequency standards.

Output Characteristics

Output Voltage and Current: Various combinations of output voltage and current may be available. For example, output voltages may include the common 5V, 12V, 24V, etc. DC voltages, and each voltage output has a corresponding current rating. For example, the 5V output may provide a current of about 10A, the 12V output provides a current of about 5A, and the 24V output provides a current of about 8A, etc. The specific parameters may vary according to the specific design of the product. These output parameters can meet the needs of different devices for power supply, such as providing suitable power supply for control circuits, sensors, actuators and other devices.

Output Voltage Accuracy: The output voltage is highly accurate and can generally be controlled between ±1% - ±3%. This means that the output voltage fluctuates less under different load conditions, which can provide stable power for the connected equipment and ensure stable operation of the equipment.

Efficiency and Power Factor

Efficiency: A high conversion efficiency, usually above 80% - 90%. High conversion efficiency means that in the process of converting input power into output power, less energy is lost, which not only reduces energy consumption and operating costs, but also reduces the heating of the module itself, improving the reliability and service life of the module.

Power factor: The power factor is generally high, for example, it can reach more than 0.9. High power factor helps to improve the energy utilisation of the grid and reduce the reactive power demand on the grid, which is in line with the requirements of energy saving and environmental protection.

Functional features

Stable power output

The internal high-precision voltage regulation circuit and stable power conversion topology can keep the output voltage stable under different load conditions. For example, when the connected equipment starts up instantly with high current or when the load changes dynamically, the module can quickly adjust the output to ensure that the voltage fluctuation is within the permissible range, providing reliable power protection for the equipment and reducing the risk of equipment failure due to power supply problems.

Perfect protection function

Over-voltage protection: Equipped with an over-voltage protection circuit, when the input voltage is too high or the output voltage exceeds the safe range due to an abnormality in the internal conversion circuit, the output will be stopped immediately to protect the connected equipment from damage caused by excessive voltage. The over-voltage protection threshold is generally set reasonably according to different output voltage levels, for example, for 24V output, the over-voltage protection threshold may be set at about 28-30V.

Overcurrent protection: The built-in overcurrent protection mechanism will automatically limit the output current or cut off the output when the output current exceeds the rated current, so as to prevent the module and equipment from being damaged due to overcurrent. This overcurrent protection function can effectively cope with abnormal conditions such as short circuit and overload of equipment.

Short-circuit protection: When a short-circuit situation occurs at the output, it can quickly detect and cut off the output current to avoid the internal circuit of the module from being damaged due to excessive short-circuit current. At the same time, the module may provide short-circuit fault indication, which is convenient for users to quickly locate and troubleshoot.

Good electromagnetic compatibility (EMC)

Strong anti-interference ability: the use of electromagnetic shielding technology and filtering circuits can effectively resist external electromagnetic interference, such as electromagnetic radiation, electrostatic discharge and other interference generated by motors, frequency converters and other equipment in industrial sites. Ensure that in the complex electromagnetic environment, the module can still work stably and output stable power.

Low Electromagnetic Radiation: During the working process, the electromagnetic radiation generated by itself is also controlled at a low level, in line with the relevant electromagnetic compatibility standards. This allows it to be installed closely with other electronic equipment without causing electromagnetic interference to the surrounding equipment, ensuring the electromagnetic compatibility of the entire system.

Thermal management optimisation

With good thermal design, such as the use of heat sinks and heat-conducting materials, it ensures that the module can effectively dissipate heat when operating at high loads. Reasonable thermal management can prevent the module from performance degradation or malfunction due to overheating, and prolong the service life of the module. At the same time, some modules may also have overheating protection, when the temperature exceeds a certain threshold, it will automatically adjust the output power or take other protective measures to ensure the safe operation of the module.
