Product Introduction
The module adopts a fully enclosed aluminum alloy shell design. The aluminum alloy material offers excellent thermal conductivity, with a thermal conduction coefficient far surpassing that of traditional plastic housings. This allows for rapid and even dispersion of heat generated by internal power components to the surface of the shell, significantly reducing the temperature of core components. As a result, the module maintains stable operation even under prolonged 5A full-load conditions, markedly extending the product’s lifespan.
In addition to its efficient heat dissipation properties, the aluminum shell provides robust physical protection and electromagnetic shielding. The high structural strength of the housing effectively resists external impacts, vibrations, and pressure, safeguarding the internal precision circuitry from mechanical damage. Simultaneously, the metal shell acts as a natural electromagnetic barrier, reducing electromagnetic interference from the module’s internal circuits to external devices and mitigating the impact of complex external electromagnetic environments on the module’s operational stability. This makes it particularly suitable for applications in challenging electromagnetic environments, such as industrial control and automotive electronics. Furthermore, the shell surface undergoes anodized treatment, offering corrosion resistance and scratch protection, making it adaptable to various harsh working conditions.

Notes for Attention
Heat Dissipation and Installation Environment
When operating at full load, the module generates a certain amount of heat. During installation, avoid blocking the heat dissipation surfaces of the aluminum casing, ensure adequate ventilation around it, and keep it away from flammable, explosive, high-temperature heat sources, and humid environments. If used in an enclosed space, it is recommended to pair the module with heat sinks or fans to assist with cooling, preventing overheating that could trigger protection mechanisms or shorten the module’s lifespan.
Special Scenario Precautions:
When used in complex electromagnetic environments such as industrial control or automotive electronics, it is recommended to install an EMI filter circuit at the module’s input to further enhance its anti-interference capability. For vehicle-mounted applications, ensure the module is securely fastened to prevent loosening or disconnection of wiring due to vibrations during vehicle operation.
Load Adaptation Limits:
The module has a rated continuous output current of 5A and a peak current of 6.5A. Avoid allowing the load current to exceed the rated value for extended periods, as this may cause performance degradation or damage to the module due to prolonged overload operation. For inductive loads (such as motors or servos), it is necessary to connect a freewheeling diode in parallel across the load terminals to suppress the impact of back electromotive force on the module.
