Bel 通过双输出直流转换器扩展铁路系统的 RCM 系列

Santa Clara, CA. [2023年8月23日] Bel Fuse Inc, a leading global manufacturer of products that power, protect, and connect electronic circuits, today announced the expansion of its RCM Series of converters with the RCM300 Series dual output DC-DC converter for railway and transportation systems.

The dual output converters are reliable power supplies, delivering 300 W at +24 V / - 24 V, the two input voltage ranges covering all common railway batteries. The two outputs are independently regulated, allowing tight and constant regulation even at extreme cross loads.

The converters are designed for chassis mounting and exhibit a closed housing. With low inrush current and extremely high efficiency and high power density, the devices are suitable for railway traction and auxiliary converters, along with railway power over ethernet (PoE) applications.

The RCM300 Series converters come with a five-year warranty and are compliant to EN 50155, EN 50121-3-2, and AREMA electrical standards, EN 45545 and NFPA 130 fire and smoke standards, and IEC/EN 62368-1 and UL/CSA 62368-1 safety standards.

Multiple feature options are available, such as an output ORing FET for redundant operation, interruption time of 10 ms (class S2), shutdown input, and an output voltage monitor controlling a relay.

加利福尼亚州圣克拉拉。 [2023年8月23日] 全球领先的电子电路供电、保护和连接产品制造商 Bel Fuse Inc 今天宣布扩展其 RCM 系列转换器，推出用于铁路的 RCM300 系列双输出 DC-DC 转换器和交通系统。

双输出转换器是可靠的电源，在 +24 V / - 24 V 时提供 300 W 的功率，两个输入电压范围涵盖所有公共铁路电池。 两个输出独立调节，即使在极端交叉负载下也能进行严格且恒定的调节。

该转换器专为底盘安装而设计，并具有封闭的外壳。 该器件具有低浪涌电流、极高效率和高功率密度，适用于铁路牵引和辅助变流器以及铁路以太网供电(PoE) 应用。

RCM300 系列转换器提供五年保修，符合 EN 50155、EN 50121-3-2 和 AREMA 电气标准、EN 45545 和 NFPA 130 防火和烟雾标准以及 IEC/EN 62368-1 和 UL/ CSA 62368-1 安全标准。

提供多种功能选项，例如用于冗余操作的输出 ORing FET、10 ms 的中断时间（S2 级）、关断输入以及控制继电器的输出电压监视器。
