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.
