For the alternate pin-out (see page 4) , add suffix “P2” to model number
(i.e.
MA424S-05RUI-P2)
Notes:
1. Cross regulation is measured with the output being tested at 100% load while the other output is varied
from 25% to 100% load.
2. See the typical connection circuit on page three for typical external filtering components. For help with a
specific model or layout issue, contact the factory.
3. Isolation voltage is specified for Input to output. On units with the optional metal case, the isolation voltage
for Input - Case and Output - Case is 1,000 VDC.
4. Operation at no-load will not damage the unit, but they may not meet all specifications. To meet all speci-
fications, a minimum load of 33% should be maintained.
5. 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.

Typical Connection
The diagram above illustrates a typical connection of the
MA400RUI
series for applications that require meeting conducted EMC standards.
The units do not require external components to operate as specified.
For applications requiring very low output noise levels, the output
filtering capacitors (C
3
is a low ESR electrolytic & C
4
is a ceramic) will
often be sufficient. Care must be taken in choosing output capacitors
not to exceed the capacitive load specification for the unit. For dual
output units, output capacitors should be connected from each output
to common. All external components should be mounted as close to
the unit as possible.
The recommended values for components are:
