Allen-Bradley 1768-PA3 是一款 CompactLogix 电源模块

Allen-Bradley 1768-PA3 是一款 CompactLogix 电源模块。它是一种双输入电源，其主要目的是通过 CompactLogix 背板供电。该电源的工作电压为 85 - 265VAC 或 108 -132VDC。在给系统通电之前，请将 1768 CompactLogix 控制器安装在与电源相同的插槽中。为避免出现问题，切勿将 1769 电源安装到 1768 CompactLogix 底板。

1768-PA3模块具有开放式外壳，可以使用DIN导轨或面板安装进行安装。LED状态指示灯允许用户实时监控模块的当前状态。1768-PA3 可以是 A 系列或 B 系列，电源端口的接线类别为 1。其兼容的电线尺寸为 14 至 22 AWG 绞合或实心铜线，额定温度为 167 华氏度，zui大隔离度为 1.2 毫米。1768-PA3 由于焊接了不可更换的保险丝，因此具有内部过流保护。它还具有用户提供的zui大过流保护 15 安培，典型效率为 75%，zui大输入功率为 120 VA 或 120 W。1768-PA3 的zui大浪涌电流在 50 至 85 伏交流电时为 132 安培，在 80 至 195 伏交流电时为 265 安培，而其功耗为 30 W.Allen-Bradley

1768-PA3 是 CompactLogix 电源。该电源专门用于 1768 产品系列。它是一种具有可选输入的电源，工作电压类别为 85 - 265VAC 或 108 -132VDC。该电源模块提供背板电源，连接的模块使用该电源为其各个电路供电。此电源不向输出模块提供输出电源。1768-PA3 的zui大输入功率为 120VA / 120W，具体取决于输入电压。

1768-PA3 电源兼容 1768 CompactLogix 控制器，如 1768-L43、1768-L43S、1768-L45 和 1768-L45S。将模块安装到任何 1768 机架时，重要的是要考虑每个模块的电源距离额定值。电源距离额定值确保模块仍能从电源接收必要的背板电源。它还确保电源的尺寸适当。如果与 1769 紧凑型 I/O 模块一起使用，1768-PA3 在同一组中zui多可容纳八 （8） 个模块。在 1768 系统中，距离额定值是 1769 I/O 模块与控制器之间的距离。

The Allen-Bradley 1768-PA3 is a CompactLogix power module. It is a dual input power supply whose primary purpose is to power through the CompactLogix backplane. The power supply operates at 85-265VAC or 108-132VDC. Before powering on the system, install the 1768 CompactLogix controller in the same slot as the power supply. To avoid problems, do not install the 1769 power supply into the 1768 CompactLogix baseplate.

The 1768-PA3 module has an open housing and can be mounted using DIN rail or panel mounting. LED status indicator allows users to monitor the current status of the module in real time. The 1768-PA3 can be A series or B series, and the wiring category of the power port is 1. It is compatible with wire sizes of 14 to 22 AWG stranded or solid copper wire with a temperature rating of 167 degrees Fahrenheit and a maximum isolation of 1.2 mm. The 1768-PA3 has internal overcurrent protection due to the welded non-replaceable fuse. It also has a user-supplied maximum overcurrent protection of 15 amps, a typical efficiency of 75%, and a maximum input power of 120 VA or 120 W. The 1768-PA3's maximum inrush current is 132 amps at 50 to 85 volts AC and 265 amps at 80 to 195 volts AC, while its power consumption is 30 W. Armen-Bradley

1768-PA3 is a CompactLogix power supply. The power supply is specially designed for the 1768 product family. It is a power supply with optional inputs, operating voltage classes of 85-265VAC or 108-132VDC. The power module provides power for the midplane. Connected modules use the power supply to power their circuits. This power supply does not supply output power to the output module. The 1768-PA3 has a maximum input power of 120VA / 120W, depending on the input voltage.

The 1768-PA3 power supply is compatible with 1768 CompactLogix controllers such as 1768-L43, 1768-L43S, 1768-L45, and 1768-L45S. When mounting modules into any 1768 rack, it is important to consider the power distance rating for each module. The power distance rating ensures that the module can still receive the necessary backplane power from the power supply. It also ensures that the size of the power supply is appropriate. If used with the 1769 compact I/O module, the 1768-PA3 can accommodate up to eight (8) modules in the same group. In a 1768 system, the distance rating is the distance between the 1769 I/O module and the controller.
