Notes:
1. When measuring output ripple, it is recommended that an external 0.47 µF ceramic capacitor be
placed from the +Vout pin to the -Vout pin for single output units and from each output to common
for dual output units. For noise sensitive applications, the use of 3.3 µF capacitors will reduce the
output ripple.
2. Transient recovery is measured to within a 1% error band for a load step change of 75% to 100%.
3. Operation at no-load will not damage these units. However, they may not meet all specifications.
4. Dual output units may be connected to provide a 24 VDC or 30 VDC output. To do this, connect the
load across the positive (+Vout) and negative (-Vout) outputs and float the output common.
5. The converter should be connected to a low ac-impedance source. An input source with a highly
inductive impedance may affect the stability of the converter. In applications where the converter
output loading is high and input power is supplied over long lines, it may be necessary to use a
capacitor on the input to insure start-up.
In this case, it is recommended that a low ESR (ESR <1.0 at 100 kHz) capacitor be mounted
close to the converter. For 24V input units a 4.7 µF is recommended; and for 48V units a 2.2 µF.
6. 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.
