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.
