Notes:
1. When measuring output ripple, it is recommended that an external ceramic
capacitor (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. Opera-
tion at no-load may cause damage to the unit.
3. These converters are specified for operation without external components.

Output ripple on single output units may be further enhanced by using the CS
terminal (single output units operated at 50% load or below should use this
function). A low ESR capaci-

the CS pin should be left open.
4. Dual output units may be connected to provide a 10V, 24V, 30V or 48 VDC
output. To do this, connect the load across the +Vout and -Vout outputs
and float the output common.
5. The remote on/off control pin is refer-

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