全方位保护机制
内置多重保护功能，覆盖电源全生命周期风险：
短路保护：输出端短路时，模块自动切断输出，故障排除后可自恢复（或手动复位，根据型号设定）；
过载保护：负载超过额定功率120%时，触发限流保护，避免模块过热损坏；
过压/欠压保护：输入电压超出115~230V AC范围，或输出电压异常（如+5V升至5.5V以上）时，模块停机保护下游设备；
过温保护：模块内部温度超过85℃时，自动降额输出，温度降至安全范围后恢复正常。

II.Key Features and Functions
High-stability power supply
Utilizing a wide input range and an efficient DC/DC converter,it can withstand power grid fluctuations(such as voltage dips and surges),ensuring low output voltage ripple and protecting sensitive components like controllers and I/O modules from power supply interference,preventing data loss or erroneous control commands.
Dynamic load response capability:When the load current changes instantaneously(e.g.,during batch switching of I/O modules),the output voltage recovery time is≤100μs,ensuring real-time system performance.Comprehensive Protection Mechanisms
Built-in multiple protection functions cover all potential risks throughout the power supply’s lifecycle:
Short-circuit protection:In case of a short circuit at the output,the module automatically shuts down the output,and can self-recover after the fault is cleared(or manually reset,depending on the model);
Overload protection:When the load exceeds 120%of the rated power,current limiting protection is triggered to prevent module overheating and damage;
Overvoltage/Undervoltage protection:If the input voltage exceeds the 115-230V AC range,or if the output voltage is abnormal(e.g.,+5V rises above 5.5V),the module shuts down to protect downstream devices;
Over-temperature protection:When the internal temperature of the module exceeds 85°C,the output power is automatically reduced,and normal operation resumes once the temperature drops to a safe range.
