Notes:
1. Load regulation is measured for a load change of 20% to 100%.
Derating Curve
2. 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.
3. Operation at no-load will not damage these units. However, they
may not meet all specifications.
4. For dual output units, the maximum capacitive load is given for
each output.
5. 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.
6. 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 5V input
units a 2.2 µF is recommended, for 12V input units, a 1.0 µF; and
for 24V units a 0.47 µF.
7. 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.
