PB271-12S-H
1. 物料型号: - 型号为PB271系列,具体型号根据输出电压和输出连接方式不同而有所区别,例如PB271-12S3表示12V输出,使用螺丝端子。

2. 器件简介: - PB271系列是一款适用于铁路应用的坚固型DC/DC转换器,输入电压范围为45-154Vdc,输出电压为12或24Vdc。该转换器能在高达60°C的环境温度下满负荷工作,无需风扇冷却,并具有过压、短路、过温、输入瞬变和反极性保护。

3. 引脚分配: - 输入和输出连接方式有三种:S(4路螺丝端子,适合4mm²电线)、C(5路笼夹端子,适合4mm²电线)、P(4路可插拔端子,适合4mm²电线)。

4. 参数特性: - 输入电压:45-154Vdc,电流:4.2A,隔离:输入到机壳2121Vdc,输入到输出4242Vdc,输出到机壳707Vdc。具有反压保护、过压保护(130% Vnom,需手动重启)、过流保护(110% Inom,自动恢复)、短路保护(自动恢复)和过温保护(110°C,自动恢复)。

5. 功能详解: - 该转换器设计用于铁路应用,能在恶劣环境下工作,具有高效率(满负荷下85%)和良好的EMC性能,符合EN50121-3-2:2000标准。

6. 应用信息: - 适用于铁路和其他需要高可靠性DC/DC转换的场合。

7. 封装信息: - 机械结构为机架安装式外壳,长度290mm,宽度80mm(无散热器)或135mm(有散热器),高度根据端子类型不同而有所差异,重量分别为1.9kg(无散热器)和2.4kg(有散热器)。
