Allen-Bradley 1756-PA75-B  标准电源 专用电源插槽上

【产品详情】

Allen-Bradley 1756-PA75是一款ControlLogix电源。这是一个标准电源，由外部供电 输入电压范围为 85-265VAC，47-63 Hz。它的额定输出功率为 75 W @ 0...+60 °C （+32...+140 °F），在 4.3VDC 时电流容量为 3A;13.5VDC 时为 1 A，2V 直流时为 8.24 A。此模块安装在 1756 机箱的最左侧。

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。

【英文介绍】

The Allen-Bradley 1756-PA75 is a ControlLogix power supply. This is a standard power supply with an externally supplied input voltage range of 85-265VAC, 47-63 Hz. It has a rated output power of 75 W @ 0... +60 °C (+32... +140 °F) with a current capacity of 3A at 4.3VDC; 1 A for 13.5VDC and 8.24 A for 2V DC. The module is installed on the leftmost side of the 1756 chassis.

The 1756-PA75 is an Allen-Bradley standard power supply. This module is mounted on a dedicated power slot 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 supplies power to the module to enter the running state.

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 is at 75... +0 °C (+60... Rated output power at +32 °F is 140 W and current capacity is 3A at 4.3VDC; 1 A for 13.5VDC and 8.24 A for 2V DC.

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 operating input power supply is suddenly interrupted, the standard power supply can provide 2 cycles of hold time @ 85V AC, 60 Hz 6 cycles @ 120V AC, 60 Hz 20 knots @ 220V AC, 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.
