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.

However, in some

applications the

addition of input/

output capacitors

will enhance stabil-

ity and reduce out-

put ripple. Recom-

mended capacitor

values are given in

the table 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 capaci-

tor is connected between

the CS pin and the -Vout pin

(the anode of the capacitor

is connected to the -Vout

pin). Recommended capacitor values are given in the table above. If not used,

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-

enced 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.
