Notes: Derating Curve
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. 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.
3. Overload protection is provided by a power limiting circuit. Long term operation
under overload conditions may cause damage to the unit.
4. Transient recovery is measured to within a 1% error band for a load step
change of 75% to 100%.
5. 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. Recommended capacitor values are:
Input Output
Vin
Capacitor Capacitor
12 VDC 100 µF 1,000 µF per 1A of Iout
24 VDC 100 µF 1,000 µF per 1A of Iout
48 VDC 100 µF 1,000 µF per 1A of Iout
For applications requiring very low output noise levels, a simple LC filter should
be effective.
6. These units should not be operated over +71°C (see derating curve). Exceeding
+71°C may damage the unit.
7. 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. Mechanical Dimensions

A simple external circuit may be used to
adjust the converter output. To adjust
the output DOWN, connect 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 poten- Mechanical Notes:
