28371 24 V供电电源套件包括24 Vdc 10 amp的供电电源,以及相应的固定和接线硬件,可将其安装到Campbell Scientific的标准机箱的内侧。带-UL选项的28371,和货号27623一样,用在Campbell Scientific组装的符合UL508A认证的机箱中。
28371套件包含DIN导轨托架、DIN导轨连接器、停止销和Phoenix供电电源。该套件不包含电池,因此使用时需要PS100、CH100、PS200、CH200或者可能更大容量的电池。
原始套件到货时没有组装,但是使用说明书提供了详细的组装信息。如果28371是与预接线的或UL认证的机箱一起订购,28371会被装配到机箱里,没有额外的费用;如果是将28371装配到标准机箱里,Campbell Scientific会收取额外的组装费用。
