Notes
1
Nominal input voltages are 24VDC and 48VDC.
2
Maximum figure, at full load.
3
Maximum.
4
Low line to high line.
5
Full load to 0.25% full load; dual outputs loaded equally.
6
Standard specifications are conservative and can be optimised for specific
applications. In particular, converter start-up at lower than specified
temperature, wider input voltage range and output voltage adjustment are
all relatively simple modifications to the standard product. Consult factory
for details.
7
Fixed frequency design provides for easier input filtering and better noise
performance.
