Models with other outputs
are available. Contact the
factory for details!!
Notes:
1. Output load regulation is specified for a load change of
20% to 100%.
2. When measuring output ripple, it is recommended that
an external 0.33
µF
ceramic capacitor be placed from the
+Vout pin to the -Vout pin.
3. Operation at no-load will not damage these units. How-
ever, they may not meet all specifications.
4. The 5V, 12V and 24V input units do not require external
components to operate, but the use of a low ESR capaci-
tor (approximately 10
uF,
ESR <1.0Ω at 100 kHz) mounted
close to the converter input pins is recommended.
For 48 VDC input units, an input capacitor should always
be used. Dependent upon the application, a value be-
tween 4.7
µF
and 47
uF
should be sufficient.
5. It is recommended that a fuse be used on the input of
a power supply for protection. See the table above for
the correct rating.
