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. However, 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 capacitor (approximately 10
µF,
ESR
<1.0Ω at 100 kHz) mounted close to the converter input pins is recom-
mended.
For 48 VDC input units, an input capacitor should always be used. Depen-
dent upon the application, a value between 4.7
µF
and 47
µF
should be
sufficient.
5. Out put capacitive load capability of these units is 33
µF
max. Exceeding
this may cause start up problems.
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.
