Specifications Section 2-2
Note The above values are for a cold start at room temperature for an AC power
supply, and for a cold start for a DC power supply.
• A thermistor (with low-temperature current suppression characteristics) 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 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.
• 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 cir-
cuits.
