Designed to support localized chassis bus segments, its onboard voltage regulation circuitry counteracts line transients and input fluctuations without degrading signal levels across parallel backplane communication lines. Internal current-limiting safeguards prevent localized overcurrent conditions from compromising adjacent processor and communication cards.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the maximum current load the 1771-P2 power supply can deliver to the backplane?\u003c\/p\u003e\n\u003cp\u003eA: The 1771-P2 provides a maximum regulated output current of 6.5 A at 5.1 VDC directly to the 1771 chassis backplane bus.\u003c\/p\u003e\n\u003cp\u003eQ: How is input AC voltage selection configured on the 1771-P2 module?\u003c\/p\u003e\n\u003cp\u003eA: Mains voltage compatibility (120 VAC or 240 VAC at 50\/60 Hz) is selected via internal jumper settings or terminal wiring configurations prior to energizing the module.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eChassis Slot Insertion:\u003c\/strong\u003e Turn off all primary power sources before mounting.
