让我们来详细分析一下：
主要产品信息和功能
制造商：Telkoor Power Supplies（有时也称为TeIKOOR）。
产品类型：CompactPCI(cPCI)交流输入电源(PSU)。
外形尺寸：6U CompactPCI。这意味着其标准模块高度(233.35毫米)可插入CompactPCI机箱。
输出功率：500瓦(W)连续输出功率。这是CompactPCI系统的强大额定功率，能够为多个cPCI板卡提供充足的电力。
输入类型：交流电(AC)输入。这意味着它可以直接连接到标准交流电源（例如100-240 VAC）。
型号名称(PSMU-350-3)：这可能指的是Telkoor CompactPCI电源系列中的特定系列或子型号。“350-3”可能表示特定的版本或功能集。
部件号(900-7002-10)：这是此特定电源配置的精确内部识别号。
核心特性和功能：
符合PICMG标准：作为cPCI电源，它完全符合PICMG 2.11电源接口规范。这确保了电气和机械兼容性，并支持cPCI系统内的热插拔功能。
多种直流输出电压：标准CompactPCI电源为背板和板卡提供所需的直流电压，通常包括：
+5V：通常具有极高的电流能力（例如数十安培）。
+3.3V：同样具有极高的电流能力。
+12V
-12V
功率因数校正(PFC)：大多数类似本产品的大功率工业电源都采用有源功率因数校正(APFC)技术。这可以提高电能质量，降低谐波失真，并确保高效利用交流电源的输入功率。
热插拔功能：这是CompactPCI的一大特色。PSMU-350-3可以在带电系统中插入或移除，而无需完全关闭系统。这对于最大限度地延长系统正常运行时间并简化维护至关重要。
N+1冗余支持：本产品很可能支持N+1冗余。这意味着可以并联多个电源，其中一个作为备用电源。如果一个活动单元发生故障，冗余单元将无缝接管，确保系统不间断供电。这通常包括主输出（+5V、+3.3V）上的有功电流共享，以均衡运行单元之间的负载。
坚固耐用的设计：Telkoor专注于生产适用于恶劣环境的电源。该电源可承受以下条件：
宽工作温度范围（Telkoor的典型工作温度范围为-5°C至+55°C，满功率下可能会降低额定值）。
抗冲击和振动。
抗电磁干扰(EMI)，确保在电气噪声很大的工业环境中稳定运行。
保护功能：包含全面的保护机制：
过压保护(OVP)
过流保护(OCP)
短路保护(SCP)
过温保护(OTP)
状态指示灯：通常在前面板上配备LED指示灯，用于显示电源状态和潜在故障情况，有助于快速诊断。

The Telkoor(often spelled TeIKOOR)PSMU-350-3 with the part number CPCIAC-6U-500 900-7002-10 is a specific model of a CompactPCI(cPCI)AC-input power supply unit(PSU).Telkoor is a reputable manufacturer known for providing rugged and reliable power solutions,especially for military,aerospace,and demanding industrial applications.
Let’s break down the details:
Key Product Details and Functions
Manufacturer:Telkoor Power Supplies(sometimes seen as TeIKOOR).
Product Type:CompactPCI(cPCI)AC-Input Power Supply Unit(PSU).
Form Factor:6U CompactPCI.This signifies a standard module height(233.35 mm)designed to plug into a CompactPCI chassis.
Power Output:500 Watts(W)continuous output power.This is a robust power rating for CompactPCI systems,capable of supplying significant power to multiple cPCI boards.
Input Type:AC(Alternating Current)input.This means it connects directly to standard AC mains power(e.g.,100-240 VAC).
Model Designation(PSMU-350-3):This likely refers to a specific series or sub-model within Telkoor’s CompactPCI power supply range.The”350-3″could indicate a particular revision or feature set.
Part Number(900-7002-10):This is the precise internal identification number for this specific configuration of the power supply.
Core Features&Capabilities:
Compliance with PICMG Standards:As a cPCI power supply,it fully complies with the PICMG 2.11 power interface specification.This ensures electrical and mechanical compatibility,as well as support for hot-swap functionality within a cPCI system.
Multiple DC Output Voltages:Standard CompactPCI power supplies provide the necessary DC voltages for the backplane and cards,typically including:
+5V:Often with very high current capability(e.g.,tens of amps).
+3.3V:Also with very high current capability.
+12V
-12V
Power Factor Correction(PFC):Most high-power industrial PSUs like this one incorporate Active Power Factor Correction.This improves power quality,reduces harmonic distortion,and ensures efficient use of the input power from the AC mains.
Hot-Swap Capability:This is a hallmark of CompactPCI.The PSMU-350-3 can be inserted or removed from a live system without requiring a full system shutdown.This is crucial for maximizing system uptime and simplifying maintenance.
N+1 Redundancy Support:It’s highly probable that this unit supports N+1 redundancy.This means multiple PSUs can be paralleled,with one unit acting as a backup.If an active unit fails,the redundant unit seamlessly takes over,ensuring uninterrupted power to the system.This often includes active current sharing on the main outputs(+5V,+3.3V)to balance the load evenly among operating units.
