1768-PA3模塊有一個(gè)開放式外殼，可以使用DIN導(dǎo)軌或面板安裝進(jìn)行安裝。LED狀態(tài)指示燈允許用戶實(shí)時(shí)監(jiān)控模塊的當(dāng)前狀態(tài)。1768-PA3可來自系列A或B，電源端口的接線類別為1。其兼容的電線尺寸為14至22AWG絞合或?qū)嵭你~線，額定溫度為167華氏度，最大絕緣為1.2毫米。由于焊接的不可更換保險(xiǎn)絲，1768-PA3具有內(nèi)部過流保護(hù)。它還具有用戶提供的15安培最大過流保護(hù)，其典型效率為75%，最大輸入功率為120VA或120w。1768-PA3的最大浪涌電流在85至132伏交流電時(shí)為50安培，在195至265伏交流電時(shí)為80安培，而其功耗為30 W,
Allen-Bradley 1768-PA3是CompactLogix電源。該電源專用于1768產(chǎn)品系列。它是一個(gè)具有可選輸入的電源，工作電壓類別為85-265VAC或108-132VDC。該電源模塊提供背板電源，連接的模塊使用該電源為各自的電路供電。該電源不向輸出模塊提供輸出功率。1768-PA3的最大輸入功率為120VA/120W，具體取決于輸入電壓。
1768-PA3電源與1768CompactLlogix控制器兼容使用，如1768-L43、1768-143$、1768-L45和1768-L45S。將模塊安裝到任何1768機(jī)架時(shí)，考慮每個(gè)模塊的電源距離額定值非常重要。電源距離額定值確保模塊仍能從電源獲得必要的背板電源。它還可以確保電源的大小得到適當(dāng)調(diào)整。如果與1769緊湊型I/O模塊一起使用，1768-PA3可在同一組中容納多達(dá)八(8)個(gè)模塊。在1768系統(tǒng)中，距離額定值是1769I/O模塊和控制器之間的距離。
該電源配有一個(gè)LED指示燈。理想情況下，通電后，LED應(yīng)該變成綠色。如果指示燈保持熄滅，請驗(yàn)證輸入電源是否有效，1768系統(tǒng)中可能存在短路或過載，或者需要更換電源。當(dāng)此LED指示燈變?yōu)榧t色時(shí)，可能意味著背板的電源輸出無效、控制器需要更換或通信、運(yùn)動模塊有故障,
Product introduction
Product Details :1768-PA3 CompactLogix Power module Used to power the CompactLogix backplane
Allen-Bradley 1768-PA3 is a CompactLogix power module. It is a dual input power supply, mainly used to power through the CompactLogix backplane. The power supply operates at 85-265 volts AC or 108-132 volts DC. Before powering on the system, install the 1768CompactLogix controller in the same row as the power supply. To avoid problems, do not install the 1769 power supply to the 1768 CompactLogix backplane.
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 derived from Series A or B, and the wiring class of the power port is 1. It is compatible with wire sizes of 14 to 22AWG stranded or solid copper wire with a temperature rating of 167 degrees Fahrenheit and a maximum insulation of 1.2 mm. Thanks to the welded non-replaceable fuse, the 1768-PA3 has internal overcurrent protection. It also features a user-supplied maximum overcurrent protection of 15 amps with a typical efficiency of 75% and a maximum input power of 120VA or 120w. The maximum inrush current of 1768-PA3 is 50 amps at 85 to 132 volts AC and 80 amps at 195 to 265 volts AC, while its power consumption is 30 W.
Allen-Bradley 1768-PA3 is a CompactLogix power supply. The power supply is dedicated to the 1768 product family. It is a power supply with selectable inputs and operates in the voltage categories of 85-265VAC or 108-132VDC. The power module provides power for the midplane. Connected modules use the power supply to power their own circuits. The power supply does not provide 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 the 1768CompactLlogix controller, such as the 1768-L43, 1768-143$, 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 still receives the necessary backplane power from the power supply. It also ensures that the size of the power supply is properly adjusted. If used with the 1769 compact I/O module, the 1768-PA3 can accommodate up to eight (8) modules in the same group. In the 1768 system, the distance rating is the distance between the 1769I/O module and the controller.
The power supply is equipped with an LED indicator. Ideally, when powered on, the LED should turn green. If the indicator remains off, verify that the input power supply is valid, there may be a short circuit or overload in the 1768 system, or the power supply needs to be replaced. When this LED indicator turns red, it may mean that the backplane's power output is invalid, the controller needs to be replaced, or the communication or motion module is faulty.
