IS220PPROS1B燃機模塊，GE電氣使用產(chǎn)品
功能100瓦電源模塊安裝在機架上直接插入機架最左側插槽中安裝在48針底板上的連接器的裝置。它提供+5伏、+12伏和-12伏電源和邏輯至背板的電平排序信號。
電源可以在單個(gè)機架中使用應用程序，或也可用于向第二個(gè)機架，如果總負載在電源額定值范圍內。
IS220PPROS1B燃機模塊通過(guò)預接線(xiàn)電纜與第二個(gè)機架互連（參見(jiàn)上一頁(yè)的訂購說(shuō)明本數據表第頁(yè)）。danThe電源輸出將通過(guò)至少一個(gè)輸入線(xiàn)路循環(huán)，輸入功率完全損失負載為過(guò)電流和過(guò)電壓故障條件提供保護。電源的操作該電源模塊可以通過(guò)以下任一方式操作：120 VAC或240 VAC標稱(chēng)輸入。它也將從標稱(chēng)125 VDC電源運行。指定的工作范圍為90 VAC至264 VAC，以及從100 VDC到150 VDC。對于連續運行（大于一小時(shí)）低線(xiàn)電壓和高溫，必須應用一些功率降額。請參閱下圖，以確定具體應用。正常工作范圍為圖中60°C的陰影區域顯示（140 F）安裝。非陰影中的操作特定應用的區域必須限制為<1小時(shí)降低最高工作溫度到55°C（131°F）將增加正常工作溫度范圍如圖所示。該電源中的有功功率因數校正電路交流輸入保持接近單位功率因數，這消除了對超大斷路器和接線(xiàn)的需要。該電路還限制了半周期峰值涌流為低值。
Functions
The 100 Watt Power Supply Module is a rack-mounted
unit that plugs directly into a 48-pin backplanemounted connector in the leftmost slot in the rack. It
provides +5 volt, +12 volt and -12 volt power, and logic
level sequencing signals to the backplane.
This power supply may be used either in a single rack
application, or may also be used to provide power to a
second rack if the total load is within the supply rating.
Interconnection to the second rack is through a prewired cable (see the ordering instructions on the last
page of this data sheet). danThe power supply output will ride through at least one
input line cycle with a total loss of input power at full
load. Protection is provided for overcurrent and overvoltage fault conditions.
Operation of the Power Supply
This Power Supply module can operate from either
120 VAC or 240 VAC nominal inputs. It will also operate from a nominal 125 VDC source. The specified
range of operation is from 90 VAC to 264 VAC, and
from 100 VDC to 150 VDC.
For continuous operation (greater than one hour) at
low line voltages and high temperatures, some powerderating must be applied. Refer to the following figure to determine the normal operating range for
specific applications. Normal operating range is
shown by the shaded area of the graph for 60C
(140F) installations. Operation in the non-shaded
region for specific applications must be limited to <1
hour. Reducing the maximum operating temperature
to 55C (131F) will increase the normal operating
range as indicated on the graph.
Active power factor correction circuits in this supply
maintain a near unity power factor for AC inputs,
which eliminates the need for oversized circuit breakers and wiring. This circuitry also limits the half cycle
peak inrush currents to a low value.
