>>>>>型號:1756-PA75-B標準電源 專用電源插槽
【功能描述】
1756-PA75是Allen-Bradley標準電源。該模塊安裝在專用電源插槽上，位于任何ControlLogix機箱的最左側。該電源的主要用途是提供必要的背板電源，供安裝在機箱上的每個模塊使用。該背板電源為模塊通電，使其進入運行狀態(tài)。
1756-PA75必須提供外部電源才能運行。它兼容85-264VAC電壓范圍，頻率為47-63 Hz，標稱輸入電壓為120VAC/240VAC。該電源在0...+60°C（+32...+140°F）下運行時的額定輸出功率為75 W，3.3VDC時的電流容量為4A;5.1VDC時為13 A，24VDC時為2.8 A。
1756-PA75與各種ControlLogix機箱兼容，例如1756-A4、1756-A7、1756-A10、1756-A13、1756-A17和機箱系列，尤其是B系列和C系列。如果1756-PA75的工作輸入電源突然中斷，該標準電源將提供2個周期的保持時間 85V AC，60 Hz 6周期 120V AC，60 Hz 20周期 220V AC，60 Hz。此外，它還具有額定值為250V（連續(xù)）、增強絕緣型、電源輸入到背板型的隔離電壓，在3500V DC下測試了60秒。1756-PA75需要硬件配置。

【英文介紹】
The 1756-PA75 is the standard Allen-Bradley power supply. This module is mounted on a dedicated power socket and is located on the far left side of any ControlLogix chassis. The main purpose of this power supply is to provide the necessary backplane power supply for each module installed in the chassis. The backplane power supply powers on the module to make it run.
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 at 0... +60°C (+32... Rated output power at +140°F is 75 W, current capacity at 3.3VDC is 4A; The value is 13 A for 5.1VDC and 2.8 A for 24VDC.
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's working input power supply is suddenly interrupted, the standard power supply will provide a hold time of 85V AC for 2 cycles, 120V AC for 6 cycles at 60 Hz, 220V AC for 20 cycles at 60 Hz, and 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.
