MPSIII系统提供5 VDC、15 VDC、-15VDC、24VDC、,

48VDC和125VDC电源至的Harmony机架组件

Symphony控制系统。MPSIII系统也可以

用于为INFI 90 OPEN系统部件供电。

MPSIII系统旨在完全取代MPSII

Harmony Rack系统中使用的系统。的组件

MPSII和MPSIII系统不能互换。这个

MPSIII系统与MPSII系统适用于相同的机柜空间,但某些机柜布置和类型可能需要

使用额外的安装装置。

注:MPSIII系统提供了一个辅助后门

安装风扇以进行适当冷却。使用MPSII系统的机柜可能不会

有这个风扇。电源托盘滑入电源机箱

用拇指螺丝固定。有15种不同的功率

供应托盘可用。参考第1节中的术语

完整列表。安装在电源机箱中的电源设备托盘

必须是相同的类型。电源托盘可以提供

5 VDC、15 VDC或-15 VDC系统的组合操作

电压,以及24 VDC、48 VDC或125 VDC现场电源。每个

电源托盘可以接受120伏交流电、240伏交流电或125伏交流电

输入功率。一对冗余供电托盘的输入电压可以来自不同的电源和不同的电压等级。交流输入具有更大的有功功率因数校正

大于0.95。共享电路允许电源托盘

相等地共享输出电流。电源托盘监视器

其输出和内部温度,并显示状态

带有LED。每个电源托盘的输入电源由连接到PEP的电源线提供。

本节包含安装时所需的信息

MPSIII系统。它包括关于特殊处理的信息,

开箱和检查、安全注意事项和接线

考虑因素。

The MPSIII system supplies 5 VDC, 15 VDC, -15VDC, 24VDC, 

48 VDC, and 125 VDC power to Harmony rack components of 

the Symphony control system. The MPSIII system can also be 

used to power INFI 90 OPEN system components.

The MPSIII system is designed to entirely replace the MPSII 

system used in Harmony Rack systems. Components of the 

MPSII and the MPSIII system are not interchangeable. The 

MPSIII system fits in the same cabinet space as the MPSII system, but some cabinet arrangements and types may require 

that additional mounting provisions be used.

NOTE: The MPSIII system has provisions for a supplemental rear door 

mounted fan for proper cooling. Cabinets using the MPSII system may not 

have had this fan.Power supply trays slide into the power chassis and are 

secured with thumb screws. There are 15 different power 

supply trays available. Refer to Nomenclature in Section 1 for 

the full listing. Power supply trays installed in a power chassis 

must be of the same type. Power supply trays can provide 

combinations of 5 VDC, 15 VDC, or -15 VDC system operating 

voltages, and 24 VDC, 48 VDC, or 125 VDC field power. Each 

power supply tray can accept 120 VAC, 240 VAC, or 125 VDC 

input power. Input voltages to a redundant pair of power supply trays may be from different sources and of different voltages. AC inputs have active power factor correction to greater 

than 0.95. Sharing circuitry allows the power supply trays to 

equally share output current. The power supply tray monitors 

its output and internal temperature and displays the status 

with an LED. Input power to each power supply tray is provided by a cord that connects to the PEP.

This section contains information needed when installing the 

MPSIII system. It includes information on special handling, 

unpacking and inspection, safety considerations, and wiring 

considerations.
