電源控制器設(shè)計(jì)用于控制和監(jiān)控19英寸機(jī)架安裝1U高

電源托架單元。它用于依次尋址每個(gè)電源組，并調(diào)整各自的

電源組電壓。

電源控制器是一個(gè)數(shù)字系統(tǒng)，通過以下方式與電源組通信

通過電源端口連接TC-323電源機(jī)框互連帶狀電纜。機(jī)框地址

使用電源端口上的跳線進(jìn)行設(shè)置，如第5.2.4.段所述。

電源控制器可通過

電源組的電壓范圍為24 V至28 V。電源通過模擬控制共享

電路。電源控制器將確保電源，無論其電壓設(shè)置如何

當(dāng)插入時(shí)（通過I2C串行數(shù)據(jù)總線）被調(diào)整為在電流/電壓范圍內(nèi)

電源的模擬控制電路的共享窗口。

前面板包含兩個(gè)開關(guān)。地址開關(guān)用于選擇電源組。

電壓開關(guān)用于升高或降低電源組的電壓。兩個(gè)顯示器

顯示該電源組的電流和電壓。

最多可以并行使用12個(gè)熱插拔電源組。電源控制器可用于

選擇一個(gè)特定的電源組的位置，并讀取從該單元汲取的電流

分辨率為100mA。

The Power Controller is designed to control and monitor the 19 inch rack mount 1U high

Power Shelf units. It is used to address each Power Pack in turn and adjust the respective

Power Pack voltage.

The Power Controller is a digital system and communicates with the Power Packs by means

of a TC-323 Power Shelf Interconnect ribbon cable, via the Power Port. The shelf addresses

are set using jumpers on the Power Port, as described in paragraph 5.2.4.

The Power Controller offers adjustment of the system voltage in 100 mV steps over the

range 24 V - 28 V for the Power Packs. Power supplies share through their analogue control

circuitry. A Power Controller will ensure that a power supply, regardless of its voltage setting

when plugged in, is adjusted (via the I2C serial data bus) to be within the current/voltage

sharing window of the power supply’s analogue control circuitry.

The front panel contains two switches. The Address switch is used to select a Power Pack.

The Voltage switch is used to raise or lower the voltage of that Power Pack. The two displays

show the current and voltage of that Power Pack.

Up to 12 hot swap Power Packs can be used in parallel. The Power Controller can be used to

select a particular Power Pack’s position and read the current being drawn from that unit

with a resolution of 100 mA.
