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 to the -Vout pins.
2. The remote On/Off control is referenced to ground. It is recommended that
connection to the pin be made through a 1kΩ resistor and diode (1N4148).
If it is not used, the control pin should be left open.
3. These units should not be operated with a load under 10% of full load. Operation
at no-load will not damage the unit, but they may not meet all specifications.
4. These converters are specified for operation without external components. How-
ever, in some applications the addition of input/ouput capacitors will enhance
stability and reduce output ripple.
For applications requiring very low output noise levels, a simple LC filter should
be effective.
5. These units should not be operated over +85°C (see derating curve). Exceeding
+85°C may damage the unit.
6. It is recommended that a fuse be used on the input of a power supply for protec-
tion. See the Model Selection table above for the correct rating.

•
On single output units, a simple external
circuit may be used to adjust the converter
output. To adjust the output DOWN, con-
nect a 5%, 3W resistor between the plus
output pin and the Vout trim pin. To adjust
the output UP, connect a 5%, 3W resistor
between the minus output pin and the
Vout trim pin.
For UP/Down trimming capability, connect
a 10 kW potentiometer between the plus
and minus outputs with the wiper arm con-
nected to the Vout trim pin.
