The remote sense pins must be connected to their respective
output pins for proper output voltage and regulation. The combined
drop on each output line to it’s respective remote sense pin must
be less than 0.3 volts or 0.6 volts for both sense lines combined.
(6)
Cross regulation is defined as the change in one output when the
other output is changed from minimum to maximum load.
(7)
Short term stability is specified after a 30 minute warm-up at full
load, constant line, load and ambient conditions.
(8)
Transient response is defined as the time for the output to settle
from a 50 to 75% step load change to a 2% error band (rise time
of step = 2 Sec).
(9)
Dynamic response is defined as the peak overshoot during a
transient as defined in note 8 above.
(10) The input ripple rejection is specified for DC to 120 Hz ripple with
a modulation amplitude of 1% of Vin.
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)
Noise is measured per CALEX Application Notes. Measurement
bandwidth is 0 - 20 MHz.
(3)
Determine the correct fuse size by calculating the maximum DC
current drain at low line input, maximum load and then adding
20 to 25% to get the desired fuse size. A slow blow type fuse is
recommended. For reverse voltage protection on the input this
fuse must be used.
(4)
Minimum load is required for rated regulation only, no module
damage will occur if the output is run at less than minimum load.
Maximum output power on the dual section is 30 Watts (i.e. one
output can draw 30 Watts and the other 0 Watts). Regulation
degrades with substantial loading unbalance.
