The internal power conversion stages ensure output voltage stability under dynamic switching loads, preserving backplane signal levels and preventing voltage ripple from impacting high-density I\/O communication cards.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What are the input voltage range options for the 1771-P2 power supply module?\u003c\/p\u003e\n\u003cp\u003eA: The 1771-P2 module accepts a nominal dual AC input of either 120 VAC (1.0 A max) or 240 VAC (0.5 A max) at 50\/60 Hz, delivering regulated 5.1 VDC output logic power.\u003c\/p\u003e\n\u003cp\u003eQ: What is the maximum current rating provided to the backplane bus by the 1771-P2?\u003c\/p\u003e\n\u003cp\u003eA: The module supplies up to 6.5 A at 5.1 VDC to the 1771 backplane logic rail.
