1.8.2 Electrical
Table 1-7 lists the electrical specifications for the RES-12XR3.
1.8.2.1 System Power
The RES-12XR3 operates with two N+1 redundant power supplies of 750-watts
capacity each that auto-range single-phase AC input from 100 to 265 Vac (47 to 63
Hertz) sources. Filtered and fused (internal) AC is supplied to each power supply
from a rear-mounted power connection.
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
supplies should be specified at the time of your order.
