P系列超薄型高可靠铁路军工用卡盒式电源

These extremely compact DC-DC converters incorporate all necessary input and output filters, signaling and protection features, which are required in the majority of applications. The converters provide important advantages, such as flexible output power through primary-side current limitation, extremely high efficiency, excellent reliability, very low ripple and RFI noise levels, full input-to-output isolation, negligible inrush current, soft start, overtemperature protection and input over- and undervoltage lockout.
The converters are particularly suitable for rugged environments, such as railway applications. They have been designed in accordance with the European railway standards EN 50155 and EN 50121-3-2. All printed circuit boards are coated with a protective lacquer. The converter inputs are protected against surges and transients occurring on the source lines and cover a total operating input voltage range from 16 to 137.5 VDC with five different model types. The outputs are continuously open- and short-circuit proof.
Full system flexibility and n+1 redundant operating mode are possible due to series or parallel connection capabilities of the outputs under the specified conditions. When several converters (with 3.3 and 5.1 V outputs) are connected in parallel, the T option allows for a single-wire connection between the converters to ensure good current sharing. LEDs at the front panel and an isolated Out-OK signal (option) indicate the status of the converter. Voltage suppressor diodes and an independent second control loop protect the outputs against an internally generated overvoltage.
The converters are designed using planar magnetics transformers and control circuits in hybrid technology. There are always two powertrains fitted to a converter, each consisting either of a regulated single output with synchronous rectifier or of a regulated main output with a tracking second output. The output power may be flexibly distributed among the main and the tracking output of each powertrain. Close magnetic coupling in the transformers and output conductors together with circuit symmetry ensure tight tracking of the auxiliary output. The switching frequency is fixed.
As a modular power supply or as part of a distributed power supply system, the low-profile design significantly reduces the required volume without sacrificing high reliability. The converters are particularly suitable for 19" rack systems occupying 3U/4TE only, but they can also be chassismounted by means of four screws. Connector type is H15 (or H15S2 for some single-output models). The fully enclosed black-coated aluminum case acts as heat sink and RFI shield and protects the converter together with the coating of all components against environmental impacts.

该系列DC-DC电源转换器内置所有必要的输入和输出滤波器，信号和保护功能，这在大多数应用中是必需的。该系列DC-DC电源转换起提供了重要的优势，例如通过初级端电流限制的灵活输出功率，极高的效率，优异的可靠性，极低的纹波和RFI噪声电平，完全输入到输出隔离，可忽略的浪涌电流，软启动，过温保护和输入过压和欠压锁定。
转换器特别适合于恶劣环境，如铁路应用。它们的设计符合欧洲铁路标准EN 50155和EN 50121-3-2。所有印刷电路板都涂有保护漆。转换器输入受到保护，防止源极线上出现的浪涌和瞬变，并覆盖从16到137.5 VDC的总工作输入电压范围，具有五种不同的型号类型。输出持续开路和短路保护。
由于在指定条件下的输出的串联或并联连接能力，全系统灵活性和n + 1冗余操作模式是可能的。当多个转换器（3.3和5.1 V输出）并联连接时，T选项允许转换器之间的单线连接，以确保良好的电流共享。前面板上的LED和隔离的Out-OK信号（选件）指示转换器的状态。电压抑制二极管和独立的第二控制环路保护输出免受内部产生的过电压。
在混合技术中使用平面磁性变压器和控制电路设计转换器。总是有两个动力系安装到转换器，每个包括具有同步整流器的稳压单输出或具有跟踪第二输出的稳压主输出。输出功率可以灵活地分布在每个动力系的主输出和跟踪输出之间。在变压器和输出导体中闭合磁耦合以及电路对称性确保辅助输出的紧跟踪。开关频率固定。
作为模块化电源或作为分布式电源系统的一部分，薄型设计显着降低了所需的体积，而不牺牲高可靠性。这些转换器特别适用于仅占用3U / 4TE的19“机架系统，但也可以通过四个螺钉进行安装，连接器类型为H15（对于某些单输出型号，则为H15S2）。全封闭黑色铝合金壳体充当散热器和RFI屏蔽，并且保护转换器以及所有部件的涂层免受环境影响。
