>>>>>型号:1756-PA75-B标准电源 专用电源插槽
【功能描述】
1756-PA75是Allen-Bradley标准电源。该模块安装在专用电源插槽上，位于任何ControlLogix机箱的最左侧。该电源的主要用途是提供必要的背板电源，供安装在机箱上的每个模块使用。该背板电源为模块通电，使其进入运行状态。
1756-PA75必须提供外部电源才能运行。它兼容85-264VAC电压范围，频率为47-63 Hz，标称输入电压为120VAC/240VAC。该电源在0...+60°C（+32...+140°F）下运行时的额定输出功率为75 W，3.3VDC时的电流容量为4A;5.1VDC时为13 A，24VDC时为2.8 A。
1756-PA75与各种ControlLogix机箱兼容，例如1756-A4、1756-A7、1756-A10、1756-A13、1756-A17和机箱系列，尤其是B系列和C系列。如果1756-PA75的工作输入电源突然中断，该标准电源将提供2个周期的保持时间 85V AC，60 Hz 6周期 120V AC，60 Hz 20周期 220V AC，60 Hz。此外，它还具有额定值为250V（连续）、增强绝缘型、电源输入到背板型的隔离电压，在3500V DC下测试了60秒。1756-PA75需要硬件配置。

【英文介绍】
The 1756-PA75 is the standard Allen-Bradley power supply. This module is mounted on a dedicated power socket and is located on the far left side of any ControlLogix chassis. The main purpose of this power supply is to provide the necessary backplane power supply for each module installed in the chassis. The backplane power supply powers on the module to make it run.
The 1756-PA75 must be supplied with an external power supply to operate. It is compatible with the 85-264VAC voltage range, the frequency is 47-63 Hz, and the nominal input voltage is 120VAC/240VAC. The power supply at 0... +60°C (+32... Rated output power at +140°F is 75 W, current capacity at 3.3VDC is 4A; The value is 13 A for 5.1VDC and 2.8 A for 24VDC.
The 1756-PA75 is compatible with various ControlLogix chassis, such as the 1756-A4, 1756-A7, 1756-A10, 1756-A13, 1756-A17 and chassis series, especially the B Series and C Series. If the 1756-PA75's working input power supply is suddenly interrupted, the standard power supply will provide a hold time of 85V AC for 2 cycles, 120V AC for 6 cycles at 60 Hz, 220V AC for 20 cycles at 60 Hz, and 60 Hz. In addition, it has a rated 250V (continuous), enhanced insulation type, power input-to-backplane type isolation voltage and was tested at 3500V DC for 60 seconds. 1756-PA75 Requires hardware configuration.
