产品说明

DSTD150 57160001-UH脉冲直流卡件电源架背面有一个可选的DSB、25针、内螺纹接口连接器。这个电力系统可以通过此接口由电力系统监控控制器，使用电源架互连。交流和直流故障报警可从电源端口上的独立连接器。

电源组是专门设计的，可作为整个分布式电力系统。保护、报警和控制功能的完整补充已纳入电源组为许多应用提供多功能性。电源组可以在带电时插入和卸下，允许“热插拔”电源组（见第4.7节）。

它们使用电源组前面的物理闩锁固定向上推以释放电源组或将其连接到电源架。电源组前面有两个指示灯：交流正常：如果输入电压在限制范围内，LED为绿色。

PWR OK（电源正常）：如果电源组正常且在操作限制范围内，LED为绿色。如果电源或风扇出现故障，指示灯呈琥珀色。过电流保护在过载情况下限制输出电流。有两种过载情况：如果负载稳定增加，单个电源组通过降低电压，因此在40 A（规格限制）时，电压降额为18.75 V。这降额电压在Trusted System Modules规格的限制范围内。如果电流快速上升时保持24 V，过电流保护将跳闸达到35 A时的电源。这种快速增加更典型的故障系统中的情况。

Product description

The DSTD150 57160001-UH Pulse DC card power supply holder has an optional DSB, 25-pin, internally threaded connector on the back. The power system can be interconnected through this interface by the power system monitoring controller using a power rack. Ac and DC fault alarms are available from a separate connector on the power port.

Power packs are specifically designed to act as an entire distributed power system. A complete complement of protection, alarm and control functions has been incorporated into the power pack to provide versatility for many applications. Power packs can be inserted and removed while energized, allowing for "hot swappable" power packs (see Section 4.7).

They use a physical latch on the front of the power pack to push up to release the power pack or connect it to the power rack. There are two indicators on the front of the power pack: AC normal: If the input voltage is within the limit, the LED is green.

PWR OK (Power normal) : If the power pack is normal and within operating limits, the LED is green. If the power supply or fan fails, the indicator is amber. Overcurrent protection Limits the output current in case of overload. There are two overload situations: If the load is steadily increasing, the individual power pack passes by lowering the voltage, so that at 40 A (specification limit) the voltage derating is 18.75 V. This derating voltage is within the limits of the Trusted System Modules specifications. If the current is maintained at 24 V while rising rapidly, the overcurrent protection will trip to the power supply at 35 A. This rapidly increases the situation in more typical failure systems.
