Specifications Section 2-2
Note (1) The above values are for a cold start at room temperature for an AC pow-
er supply, and for a cold start for a DC power supply.
• A thermistor (with low-temperature current suppression characteris-
tics) is used in the inrush current control circuitry for the AC power
supply. The thermistor will not be sufficiently cooled if the ambient
temperature is high or if a hot start is performed when the power sup-
ply has been OFF for only a short time, so in those cases the inrush
current values may be higher (as much as two times higher) than
those shown above.
• A capacitor delay circuit is used in the inrush current control circuitry
for the DC power supply. The capacitor will not be charged if a hot
start is performed when the power supply has been OFF for only a
short time, so in those cases the inrush current values may be higher
(as much as two times higher) than those shown above.
• Always allow for this when selecting fuses and breakers for external
circuits.
(2) General specification of Expansion I/O Units and Expansion Units will be
the same criteria with CPU Units.
