1756-PB72 电源的浪涌瞬态抗扰度在信号端口上为 +/- 1 kV 线对线 （DM） 和 +/- 2 kV 线对地 （CM）。该电源的传导射频抗扰度为 10 Vrms，在 150 kHz 至 80 MHz 范围内具有 1 kHz 正弦波 80% AM。1756-PB72 的 EFT/B 抗扰度在信号端口上为 +/- 4 kV（5 kHz）。1756-PB72 不打算在住宅区使用，并且可能无法在此类环境中提供足够的无线电通信服务保护。

部件号为 1756-PB72 的 ControlLogix 模块是 ControlLogix 电源。此电源用于为分布在 ControlLogix 机箱中的背板供电。它兼容安装到任何 A、B 和 C 系列 ControlLogix 机箱上。

1756-PB72 需要 24VDC 的标称输入电源。一旦提供电源，该模块可以在 3.3V 时提供 4A 的输出电流;5.1V 时为 10A，24V 时为 2.8A。电源模块的安装位置位于机箱的最左侧。

任何 ControlLogix 机箱都配有电源插入插槽，该插槽不占用模块中的任何插槽。该电源模块与机箱一起直接安装在安装板上，通过提供的安装孔固定到位。由于机箱和此电源模块直接接触安装板，因此强烈建议机箱的接地端子与电源正确连接。

由于这是直流电源，因此该装置已提供电线端子。一旦盖门弹出，就可以进入该终端。端子有清晰的标记，例如DC+表示正电源，DC-表示负电源返回。建议将保护接地连接到机箱接地或接地总线。 该电源配有一个简单的状态指示灯，可直观地报告模块的运行情况。

【英文介绍】

The Allen-Bradley 1756-PB72 ControlLogix standard DC power supply has a power input of 24V DC. The 1756-PB72 offers built-in overcurrent protection. The power supply also features an enhanced insulation tested at 3,500V DC for 60 seconds. The 1756-PB72 power supply has an input frequency of 47-63 Hz. The 1756-PB72 measures 140 x 112 x 145 mm (5.51 x 4.41 x 5.71 inches). The power supply weighs about 0.95 kg (2.10 lb). It can operate at 5-95% relative humidity without condensation. The power supply has an operating vibration of 500 G at 2-10 Hz. The operating shock and non-operating shock of the power supply are 30 G and 50 G respectively. The 1756-PB72 operates at 0-60°. Celsius (32-140 degrees Fahrenheit), the non-operating temperature of this power supply is -40-85 degrees. Degrees Celsius (-40-185° C). Fahrenheit).

The surge transient immunity of the 1756-PB72 power supply is +/ -1 kV wire-to-wire (DM) and +/ -2 kV wire-to-ground (CM) at the signal port. The power supply has a conducted RF immunity of 10 Vrms and a 1 kHz sine wave 80% AM in the range of 150 kHz to 80 MHz. The EFT/B immunity of the 1756-PB72 is +/ -4 kV (5 kHz) at the signal port. The 1756-PB72 is not intended for use in residential areas and may not provide adequate protection for radio communication services in such environments.

The ControlLogix module with part number 1756-PB72 is the ControlLogix power supply. This power supply is used to power the backplane distributed in the ControlLogix chassis. It is compatible to install on any A, B, and C series ControlLogix chassis.

The 1756-PB72 requires a nominal input power supply of 24VDC. Once powered, the module can deliver 4A output current at 3.3V; It is 10A at 5.1V and 2.8A at 24V. The Psus are installed on the left side of the chassis.

Any ControlLogix chassis is equipped with a power insertion slot that does not take up any slot in the module. The PSU and chassis are directly installed on the installation plate and secured in place through the installation holes provided. Because the chassis and the PSU are in direct contact with the mounting board, it is strongly recommended that the grounding terminal of the chassis be properly connected to the power supply.

Since this is a DC power supply, the device is supplied with wire terminals. Once the cover door pops up, you can access the terminal. The terminals are clearly marked, such as DC+ for positive power supply and DC- for negative power return. You are advised to connect the protection grounding to the chassis grounding or grounding bus. The power supply is equipped with a simple status indicator that visually reports the module's operation.
