Notes:
1. Output load regulation is speci ed for a load change of 20%
Derating Curve
to 100%.
2. When measuring output ripple, it is recommended that
an external 0.33 F ceramic capacitor be placed from the
+Vout pin to the -Vout pin.
3. Operation at no-load will not damage these units. However,
they may not meet all speci cations.
4. The 5V, 12V and 24V input units do not require external
components to operate, but the use of a low ESR capacitor
(approximately 10 uF, ESR <1.0 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 between
4.7 F and 47 uF should be suf cient.
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.
