Notes:
1. When measuring output ripple, it is recommended that an external ceramic capacitor (approx. 1 µF to 10 µF) be placed from Mechanical Dimensions
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.
Input Output
3. These converters are specified for operation without external Vin Capacitor Vout Capacitor
components. However, in some applications the addition of
input/output capacitors will enhance stability and reduce output 5 VDC 100 µF 5 VDC 47 µF
ripple. Recommended capacitor values are given in the table
12 VDC 100 µF 12 VDC 47 µF
at right.
Output ripple on single output units may be further enhanced 24 VDC 10 µF 15 VDC 47 µF
by using the CS terminal (single output units operated at 50% 48 VDC 10 µF
load or below should use this function). A low ESR capacitor is Output Voltage
connected between the CS pin and the -Vout pin (the anode of
the capacitor is connected to the -Vout pin). Recommended 5V 12V 15V 24V
capacitor values are given in the table above. If not used, the CS (µF) 47 - 100 22 - 47
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 Min Max
current to the pin should be between 5 - 10 mA with a maximum of On <0.6 VDC to Open Circuit
20 mA. Exceeding 20 mA could cause damage to the unit. Off 2.7 VDC 15.0 VDC
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.
