1756-PA75-B 标准电源

1756-PA75 是艾伦-布拉德利标准电源。此模块安装在专用电源插槽上，该插槽位于 ControlLogix 机箱的最左侧。此电源的主要目的是提供必要的背板电源，供安装在机箱的每个模块使用。该背板电源为模块通电以进入运行状态。

必须为 1756-PA75 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，而标称输入电压为 120VAC / 240VAC。该电源在 75...+0 °C （+60...+32 °F） 下运行时的额定输出功率为 140 W，在 4.3VDC 时电流容量为 3A;13.5VDC 时为 1 A，2V 直流时为 8.24 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，该标准电源可提供 2 个周期的保持时间 @ 85V AC， 60 赫兹 6 周期 @ 120V 交流电，60 赫兹 20 节 @ 220V 交流电，60 赫兹。 此外，它还具有额定值为 250V（连续）、增强绝缘型、电源输入至背板型的隔离电压，在 3500V DC 下进行了 60 秒的测试。 1756-PA75 需要硬件配置

1756-PA75 is an Allen Bradley standard power supply. This module is installed on a dedicated power slot, which is located on the far left side of the ControlLogix chassis. The main purpose of this power supply is to provide the necessary backplane power for each module installed in the chassis. The backplane power supply powers up the module to enter the operating state.

External power supply must be provided for 1756-PA75 to operate. It is compatible with the voltage range of 85-264VAC, with a frequency of 47-63 Hz, and a nominal input voltage of 120VAC/240VAC. The rated output power of this power supply is 140 W when operating at 75...+0 ° C (+60...+32 ° F), and the current capacity is 3A at 4.3VDC; 1 A at 13.5VDC and 8.24 A at 2V DC.

1756-PA75 is compatible with various ControlLogix chassis, such as 1756-A4, 1756-A7, 1756-A10, 1756-A13, 1756-A17, and chassis series, especially B-series and C-series. If the working input power of 1756-PA75 is suddenly interrupted, this standard power supply can provide 2 cycles of hold time @ 85V AC, 6 cycles @ 120V AC at 60 Hz, 20 cycles @ 220V AC at 60 Hz, and 60 Hz. In addition, it also has a rated value of 250V (continuous), enhanced insulation type, and power input to backplane type isolation voltage, which was tested for 60 seconds at 3500V DC. 1756-PA75 requires hardware configuration
