The IC200PWR002 is the DC-input expanded power supply for Emerson's VersaMax platform — converting 24 VDC control power into the dual 5 VDC and 3.3 VDC backplane voltages that power the CPU, NIU, and I/O modules. Despite some listings mislabeling it as an "input module," the IC200PWR002 is a power supply in every functional sense: it rectifies and regulates DC input to dual regulated DC outputs, includes short-circuit protection, overload protection, and reverse-polarity protection on the input terminals, and provides 10 ms of hold-up time to ride through brief voltage dips. The key differentiator from the standard IC200PWR001 is the expanded 3.3 VDC rail: 1.0 A available versus 0.25 A on the standard model. As newer VersaMax modules with FPGAs and high-density logic increasingly draw from the 3.3 V rail, the PWR002 provides the headroom that the PWR001 does not — a rack with several IC200MDD841 mixed modules (each drawing 30 mA at 5 V) and a high-speed counter module may run the 5 V rail lightly loaded while exhausting the 3.3 V capacity of a standard supply. The PWR002 solves this without requiring a second power supply booster carrier for the same rack.
