Notes:
1. When measuring output ripple, it is recommended that an external ceramic capaci-
tor (approx. 1 µF to 10 µF) be placed from the +Vout pin to the -Vout pin for single
output units and from each output to common for dual output units.
2. These units should not be operated with a load under 10% of full load. Operation
at no-load may cause damage to the unit.
3. These converters are specified for operation without external components. However,
in some applications the addition of input/output capacitors will enhance stability and
reduce output ripple.

low ESR capacitor is connected between
the CS pin and the -Vout pin (the anode of the capacitor is connected to the -Vout
pin). Recommended capacitor values are given in the table above. If not used, the
CS pin should be left open.
4. Dual output units may be connected to provide a 10V, 18V, 24V or 30 VDC output.
To do this, connect the load across the +Vout and -Vout outputs and float the
output common.

6. It is recommended that a fuse be used on the input of a power supply for protec-
tion. See the Model Selection table above for the correct rating.
