Mechanical notes
A All pins are actual to within 0.010 inch (0.25mm) diameter.
B Tolerances:
Imperial
0.XX ± 0.02 inch
0.XXX ± 0.005 inch
Metric
0.X ± 0.5mm
0.XX ± 0.13mm
Unless otherwise specified.
C Metric dimensions in brackets, e.g. 1.250” (31.75mm).
D Copper tracks must not be routed under the four converter stand-offs.
Total error band is defined at the static output regulation at 25°C, includ-
ing initial setting accuracy, line voltage within stated limits and load cur-
rent within stated limits.
2 Nominal input voltages are 24VDC and 48VDC.
3 Overvoltage protection threshold. Any main output overvoltage clamps
the output to a very low output voltage. A prolonged overvoltage
condition will cause the converter to fail.
4 Maximum value at full load, nominal input voltage.
5 For top-mounted heatsink option with Metric screws, add ‘-MX’ or ‘-MY’
to these model numbers. For side-mounted heatsink option, add ‘-ME’ or
‘-MS’ to the model number e.g.
NFC40-48S05-MX.
For top-mounted heatsink option with Imperial screws, add ‘-1X’ or ‘-1Y’
to these model numbers. For side-mounted heatsink option, add ‘-1E’ or
‘-1S’ to the model number e.g.
NFC40-48S05-1X.
6 For triple output units, common pins (5 and 8) should be connected
externally.
7 Output V1 must return to common 1 and outputs V2 and V3 to common 2
and 3 respectively in order to meet noise and regulation specifications.
8 The external trim function enables the tailoring of the output voltage to
the applications exact requirements. Adjustments within ±10% are
possible. On the triple output models the auxiliary output voltages (output
2 and 3) will vary proportionally to the main output.
9 An external filter capacitor is required for normal operation. The
capacitor should be capable of handling 1A/2A ripple current for 48V/24V
