1756-PB72电源在信号端口上的浪涌瞬变抗扰度为+/- 1 kV线-线（DM）和+/- 2 kV线-地（CM）。该电源的传导射频抗扰度为10 Vrms，1 kHz正弦波80% AM范围为150 kHz至80 MHz。1756-PB72在信号端口5 kHz时的EFT/B抗扰度为+/- 4 kV。1756-PB72不适用于住宅区，可能无法在这种环境中提供足够的无线通信服务保护。

部件号为1756-PB72的ControlLogix模块是ControlLogix电源。该电源用于为背板供电，背板在ControlLogix机箱中分布。它可兼容安装到任何A、B和C系列ControlLogix机箱上。

1756-PB72需要24VDC的标称输入电源。一旦供电，模块可以提供3.3V的4A输出电流；5.1V时为10A，24V时为2.8 A。

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。由于机箱和电源模块直接接触安装板，强烈建议正确连接机箱和电源的接地端子。

由于这是一个DC电源，该装置已经提供了接线端子。一旦盖门弹出，就可以接触到该终端。端子有清晰的标记，如DC+表示正极电源，DC-表示负极电源回路。建议将保护接地连接到底盘接地或接地总线。

该电源配有一个简单的状态指示器，可直观地报告模块的运行情况。在模块的右上部分安装了一个LED灯。

The Allen-Bradley 1756-PB72 ControlLogix Standard DC Power Supply has a power input of 24V DC. The 1756-PB72 provides built-in overcurrent protection. The power supply also has a type of reinforced insulation tested at 3,500V DC for 60 seconds. The input frequency of the 1756-PB72 power supply is from 47-63 Hz. The dimensions of the 1756-PB72 are 140 x 112 x 145 mm (5.51 x 4.41 x 5.71 inches). The weight of this power supply is around 0.95 kg (2.10 lb). It can operate at a relative humidity of 5-95% non-condensing. The operational vibration of this power supply is 2 G at 10-500 Hz. The operating shock and the nonoperating shock of this power supply are 30 G and 50 G respectively. The 1756-PB72 has an operating temperature from 0-60 °. Celsius (32-140 deg. Fahrenheit) and the non-operating temperature of this power supply is -40-85 deg. Celsius (-40-185 °. Fahrenheit).

The surge transient immunity of the 1756-PB72 power supply is +/- 1 kV line-line (DM) and +/- 2 kV line-earth (CM) on signal ports. The conducted RF immunity of this power supply is 10 Vrms with 1 kHz sine-wave 80% AM from 150 kHz to 80 MHz. The EFT/B immunity of the 1756-PB72 is +/- 4 kV at 5 kHz on signal ports. The 1756-PB72 is not intended to be used in a residential neighborhood and may not provide adequate protection against radio communication services in such an environment.

The ControlLogix module with part number 1756-PB72 is a ControlLogix Power Supply. This Power Supply is used to provide power to the backplane which is being distributed across the ControlLogix chassis. It is compatible for installation to any Series A, B and C ControlLogix chassis.

The 1756-PB72 requires a nominal input supply of 24VDC. Once power supply is provided, the module can provide output Currents of 4A at 3.3V; 10A at 5.1V and 2.8 A at 24V.

The Power supply module’s installation location is located at the leftmost part of the chassis. Any ControlLogix chassis is provided with Power Supply insertion slot which does not take up any slot in the module. This power supply module is installed along with the chassis directly on the mounting plate, fixed in position by the provided mounting holes. As the chassis and this power supply module directly contacts the mounting plate, it is highly recommended that the ground terminals of the chassis and the power supply are properly connected.

As this is a DC power supply, wire terminal is already provided with the unit. This terminal is accessible once the cover door is popped-out. The terminals have clear markings such as DC+ for the positive supply and DC- for the negative supply return. The protective earth is recommended for attaching to the chassis ground or ground bus.

This power supply is provided with a simple status indicator to visually report the operation of the module. It has a single LED light installed at the upper right section of the module.
