DC/DC 转换器功能与应用场景

1. 核心功能

  • 电压转换：将输入的 24V DC 稳压为 12V DC 输出，额定电流 5A（60W），适用于需要 12V 供电的设备（如传感器、控制器、继电器等）。
  • 隔离与滤波：输入与输出电气隔离，有效舒缓共模干扰，提供纯净电源，保护敏感电子元件。
  • 过载保护：具备 自动恢复式过载保护（较好 150% 额定电流）和 短路保护，确保安全运行。
  • 高效率：转换效率高达 95%，减少能量损耗，降低发热，延长使用寿命。

2. 典型应用场景

  • 工业自动化系统：为 PLC 模块、传感器（如激光测距仪、压力变送器）提供稳定的 12V 电源。
  • 精密仪器：健康设备、测试仪器等对电源波动敏感的设备，需要低纹波、高稳定性的供电。
  • 混合电压系统：在同一控制柜中，同时需要 24V 和 12V 电源时，通过 DC/DC 转换器从主电源派生次级电压。
  • 替代场景：替代传统变压器或线性电源，提供更紧凑、高效的解决方案。
