Derating Curve
For models with a metal case, add an
"M" to the model number (ie: A115ERUM)
Notes:
1. Exceeding the input range by a significant margin may damage the units. For 24V input the
input voltage should not exceed 40V; for 48V models it should not exceed 80V.
2. When measuring output ripple, it is recommended that an external 0.33 µF ceramic capacitor
be placed from the +Vout pin to the -Vout pin for single output units and from each output to common
for dual output units.
3. The optional metal package is nickel plated steel. Dimensions are 1.25 x 0.80 x 0.39 Inches (31.8 x
20.3 x 10.0 mm).
4. These units should not be operated with a load under the specified minimum. Operation at
no-load will increase ripple significantly and may cause damage to the unit.
5. 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:
Output Capacitor
Vin Input Vout
(VDC) Capacitor (VDC) 0 to +70ºC -40 to +85ºC Mechanical Dimensions
(Electrolytic) (Tantalum)
Sing 10 µF 3.3 100 µF 47 µF
24
Dual 10 ~ 47 µF 5 100 µF 47 µF
Sing 10 µF 12 100 µF 47 µF
48
Dual 10 ~ 47 µF 15 100 µF 47 µF
For applications requiring very low output noise levels, a simple LC filter should
be effective.
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.
