When measuring output ripple, it is recommended that an external ceramic capacitor (approx 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/ouput capacitors will enhance stability and reduce output ripple. Recommended capacitor values are: Vin Input Capacitor Vout Output Capacitor 24 VDC 48 VDC 100 µF 100 µF 5 VDC 12 VDC 15 VDC 24 VDC 100 µF /1A 100 µF /1A 100 µF /1A 100 µF /1A Rating Efficiency Fuse Slow-Blow (%, Typ) (mA) 77 80 81 73 75 77 79 81 79 82 85 86 75 78 82 85 700 700 700 700 700 700 700 700 350 350 350 350 350 350 350 350 Derating Curve 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, 24V, 30V or 48 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.
