IS220PPROS1B燃机模块，GE电气使用产品
功能100瓦电源模块安装在机架上直接插入机架最左侧插槽中安装在48针底板上的连接器的装置。它提供+5伏、+12伏和-12伏电源和逻辑至背板的电平排序信号。
电源可以在单个机架中使用应用程序，或也可用于向第二个机架，如果总负载在电源额定值范围内。
IS220PPROS1B燃机模块通过预接线电缆与第二个机架互连（参见上一页的订购说明本数据表第页）。danThe电源输出将通过至少一个输入线路循环，输入功率完全损失负载为过电流和过电压故障条件提供保护。电源的操作该电源模块可以通过以下任一方式操作：120 VAC或240 VAC标称输入。它也将从标称125 VDC电源运行。指定的工作范围为90 VAC至264 VAC，以及从100 VDC到150 VDC。对于连续运行（大于一小时）低线电压和高温，必须应用一些功率降额。请参阅下图，以确定具体应用。正常工作范围为图中60°C的阴影区域显示（140 F）安装。非阴影中的操作特定应用的区域必须限制为<1小时降低最高工作温度到55°C（131°F）将增加正常工作温度范围如图所示。该电源中的有功功率因数校正电路交流输入保持接近单位功率因数，这消除了对超大断路器和接线的需要。该电路还限制了半周期峰值涌流为低值。
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.
