Notes:
Derating Curve
1. When measuring output ripple, it is recommended that an external 0.47 µF ceramic ca-
pacitor 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 10 VDC, 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 <1.0Ω at 100 kHz) capacitor be mounted
close to the converter. For 5V input units a 8.2 µF is recommended, for 12V input units,
a 3.3 µF; and for 24V & 48V units a 2.2 µF.
Mechanical Dimensions
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.
