电源控制器设计用于控制和监控19英寸机架安装1U高

电源托架单元。它用于依次寻址每个电源组，并调整各自的

电源组电压。

电源控制器是一个数字系统，通过以下方式与电源组通信

通过电源端口连接TC-323电源机框互连带状电缆。机框地址

使用电源端口上的跳线进行设置，如第5.2.4.段所述。

电源控制器可通过

电源组的电压范围为24 V至28 V。电源通过模拟控制共享

电路。电源控制器将确保电源，无论其电压设置如何

当插入时（通过I2C串行数据总线）被调整为在电流/电压范围内

电源的模拟控制电路的共享窗口。

前面板包含两个开关。地址开关用于选择电源组。

电压开关用于升高或降低电源组的电压。两个显示器

显示该电源组的电流和电压。

最多可以并行使用12个热插拔电源组。电源控制器可用于

选择一个特定的电源组的位置，并读取从该单元汲取的电流

分辨率为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.
