P系列超薄型高可靠鐵路軍工用卡盒式電源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.

該系列DC-DC電源轉(zhuǎn)換器內(nèi)置所有必要的輸入和輸出濾波器，信號和保護功能，這在大多數(shù)應用中是必需的。該系列DC-DC電源轉(zhuǎn)換起提供了重要的，例如通過初級端電流限制的靈活輸出功率，高的效率，優(yōu)異的可靠性，低的紋波和RFI噪聲電平，完全輸入到輸出隔離，可忽略的浪涌電流，軟啟動，過溫保護和輸入過壓和欠壓鎖定。
轉(zhuǎn)換器特別適合于惡劣環(huán)境，如鐵路應用。它們的設計符合歐洲鐵路標準EN 50155和EN 50121-3-2。所有印刷電路板都涂有保護漆。轉(zhuǎn)換器輸入受到保護，防止源線上出現(xiàn)的浪涌和瞬變，并覆蓋從16到137.5 VDC的總工作輸入電壓范圍，具有五種不同的型號類型。輸出持續(xù)開路和短路保護。
由于在條件下的輸出的串聯(lián)或并聯(lián)連接能力，全系統(tǒng)靈活性和n + 1冗余操作模式是可能的。當多個轉(zhuǎn)換器（3.3和5.1 V輸出）并聯(lián)連接時，T選項允許轉(zhuǎn)換器之間的單線連接，以確保良好的電流共享。前面板上的LED和隔離的Out-OK信號（選件）指示轉(zhuǎn)換器的狀態(tài)。電壓抑制二管和的第二控制環(huán)路保護輸出免受內(nèi)部產(chǎn)生的過電壓。
在混合技術中使用平面磁性變壓器和控制電路設計轉(zhuǎn)換器?？偸怯袃蓚€動力系安裝到轉(zhuǎn)換器，每個包括具有同步整流器的穩(wěn)壓單輸出或具有跟蹤第二輸出的穩(wěn)壓主輸出。輸出功率可以靈活地分布在每個動力系的主輸出和跟蹤輸出之間。在變壓器和輸出導體中閉合磁耦合以及電路對稱性確保輔助輸出的緊跟蹤。開關頻率固定。
作為模塊化電源或作為分布式電源系統(tǒng)的一部分，薄型設計顯著降低了所需的體積，而不犧牲高可靠性。這些轉(zhuǎn)換器特別適用于僅占用3U / 4TE的19“機架系統(tǒng)，但也可以通過四個螺釘進行安裝，連接器類型為H15（對于某些單輸出型號，則為H15S2）。全封閉黑色鋁合金殼體充當散熱器和RFI屏蔽，并且保護轉(zhuǎn)換器以及所有部件的涂層免受環(huán)境影響。
