Electrical Table 1-7 lists the electrical specifications for the RES-XR4-3U.
1.5.1.1 System Power
The RES-XR4-3U operates with two N+1 redundant power supplies of 750-watts
capacity each that auto-range single-phase AC input from 100 to 240 Vac (47 to 63
Hertz) sources. Filtered and fused (internal) AC is supplied to each power supply
connection. In the event the system is ordered with a single power supply, a
dummy/blank power supply will occupy the other bay, and in such configuration,
there is no redundancy in the power supply subsystem.
Two optional N+1 redundant DC power supplies of 750 watts (48 volts) or 500 watts
(28 volts) each may be substituted for the AC power supplies (see Table 1-7 ). These
power supplies have the same form factor as the AC supply, except that the power
supply spec’ed as MIL-STD-461 is double wide, and occupies both power supply
bays. In this case there is no redundancy in the power supply subsystem.Power sup-
ply options should be specified at the time of your order.
