A-B 81007-465-51-R电压反馈模块
输出保护继电器输出可以通过以下方式进行外部保护，以防感应负载产生寄生虫：-变阻器或RC模块，交流-自由轮二极管，直流。外部热熔断器连接到输出的公共电源，保护输出连接的设备。1.4.7.4 CS 31总线的布线CS 31总线是RS 485串行接口，由屏蔽双绞线组成。此总线是主从总线，仅接受单个主总线。使用AWG 24（0.22 mm 2）至AWG 18（0.18 mm 2）双绞线。最大长度为500米。整个系统总线设置应使用相同的电缆类型。例如，在机柜电缆连接期间，应避免总线中断，否则应将其连接到接线板的同一侧。警告：不允许总线的STAR连接！中央和远程装置可连接在总线的任何点上：-总线1上的总线1-总线2上的总线2-端子排1的端子3上的屏蔽（最好是编织）和主级接地（电缆<1 m）。总线应以120Ω 连接至总线终端的1/4 W电阻。双绞线应对称
产品概述
Trusted®电源系统是一种高密度灵活电源，用于转换110 Vac或240 Vac的主线电压。可信产品的输出为24 Vdc或28 Vdc可调现场电源。Trusted Power System由一个带机械支撑的1U电源架组成，其中最多包含三个750 W电源组。电源组在使用一个或多个电源架的配置中共享负载。每个电源组都有一个单独的电源连接，通过一个机械固定的IEC 60320型连接器。每个电源架可以从单个电源提供2250 W或1500 W的电源，并具有n+1冗余。可以连接多个单元以满足更多容量或冗余要求。电源组状态的诊断信息通过连接到电源架后部的电源端口提供。该设备监测输入和输出条件，并使用继电器触点报告超出范围的故障和超温/风扇故障。电源端口还允许连接可选的机架式电源控制器，用于实时配置输出电压和电流，监控4个电源架中最多12个电源组。
特点：•冗余和N+1配置。•可热更换电源组。•电流共享。•电流限制。•功率因数校正。•诊断触点。•可配置输出电压。•每个电源组的输入/输出故障诊断。
Output protection
The relay outputs may be protected externally against parasites generated by an inductive load with: - a varistor or an RC module, in alternating current - a free-wheel diode, in direct current The presence of an external thermal fuse, connected to the common power supply of the outputs, protects to the output connected devices. 1.4.7.4 Cabling of the CS 31 bus The CS 31 bus is a RS 485 serial interface and consists of a shielded twisted pair. This bus is a master slave bus and only accepts a single master. Use a AWG 24 (0.22 mm 2 ) to AWG 18 (0.18 mm 2 ) twisted pair. The maximum length is 500 m. The same cable type should be used for the whole system bus setup. Bus interruptions should be avoided, during cabinet cable connections for instance, otherwise it should be cabled to the same side of the terminal block Warning: STAR connection of the bus is not permitted! The central and remote units may be connected at any point of the bus: - bus 1 on bus 1 - bus 2 on bus 2 - shielding (preferably braided) on terminal 3 of terminal block 1 and earth connected at the master level (cable < 1 m) The bus should be terminated with a 120 Ω 1/4 W resistance connected to the bus extremities. The twisted pair should be symmetrical
Product Overview
The Trusted® Power System is a high density flexible power supply designed to convert main line voltages of either 110 Vac or 240 Vac. Outputs are either 24 Vdc for Trusted product or 28 Vdc adjustable field power. The Trusted Power System consists of a 1U Power Shelf with mechanical support, containing up to three 750 W Power Packs. The Power Packs load share in configurations using one or more Power Shelves. Each Power Pack has an individual supply connection via a mechanically retained IEC 60320 type connector. Each Power Shelf can supply 2250 W of power or 1500 W with n+1 redundancy from a single source. Multiple units can be connected for further capacity or redundancy requirements. Diagnostic information of Power Pack status is provided via the Power Port, which connects to the rear of the Power Shelf. This device monitors input and output conditions and reports out of range faults and over-temperature/fan failure using relay contacts. The Power Port also allows connection of the optional rack mounted Power Controller for live configuration, of output voltage and current, monitoring up to 12 Power Packs in 4 Power Shelves.
Features: • Redundant and N+1 configurations. • Hot replaceable Power Packs. • Current sharing. • Current limiting. • Power factor correction. • Diagnostic contacts. • Configurable output voltage. • Input/output fail diagnostics per power pack.
