Notes: 1. When measuring output ripple, it is recommended that an external ceramic capacitor (approx approx 1 F to 10 F) 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/ouput capacitors will enhance stability and reduce output ripple. Recommended capacitor values are:

Mechanical Dimensions
For applications requiring very low output noise levels, a simple LC filter should be effective. 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 positive (+Vout) and negative (-Vout) outputs and float the output common. 5. 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.
