CIRCUITRY
Maximum Current Versus
Ambient Temperature
The chart indicates continuous current to limit
the junction temperatures to 100°C. Information
is based on steady state heat transfer in a two
cubic foot sealed enclosure.
Figure 1
FUSES
G5 Fuses are 5 Amp Littelfuse part number
217005 or equivalent.
Figure 2
Maximum Peak Surge Current
Versus Surge Duration (AC Outputs)
Information is based on a supply frequency of
60 Hz sinusoidal and a resistive or inductive
load. Application of maximum surge current
may not be repeated until the module
temperature has returned to its steady state
value.
