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. 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. Recommended
capacitor values are given at right.
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 capacitor is connected between the CS pin and the -Vout
pin (the capcitor anode connected to the -Vout pin). Recommended
capacitor values are given in the table at right. If not used, the CS
pin should be left open.
4. Dual output units may be connected to provide a 10V, 24V or 30 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 referenced to the -Vin pin. Input current
to the pin should be between 5 - 10 mA with a maximum of 20 mA.
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.
