NOTES
*
All parameters measured at Tc=25°C, nominal input voltage
and full rated load unless otherwise noted. Refer to the
CALEX Application Notes for the definition of terms,
measurement circuits and other information.
(2)
Determine the correct fuse size by calculating the maximum DC
current drain at low line input , maximum load(or use the supplied
curves) and then adding 20 to 25 percent to get the desired fuse
size.
(3)
Maximum output power is 30 Watts. This power can be drawn
from any output combination so long as the sum of both outputs
power never exceeds 30 Watts (i.e. one output can draw 0 Amps
and the other can draw twice it’s rated full load current).
Regulation degrades with substantial unbalance. Minimum load
is required for proper regulation only; no module damage is
sustained if run at less than minimum load.
(4)
Cross regulation is defined as the change in one output when the
other output is changed from minimum to maximum load.
(5)
Short term stability is specified after a 30 minute warm-up atfull
load.
(6)
Transient response is defined as the time for the output to settle
from a 25 to 75 % step load change to a 1% error band (rise time
of step = 2 Sec).
