Notes:

1. When measuring output ripple & noise,it is recommended that an external capacitor

(1 µF to 10 µF) be placed from the +V^OUTto the -VOUT pins.

2. Transient recovery is measured to within a 1% error band for a load step change

5. To meet the requirements of EN 61000-4-4 ( 2 kV), external components are

needed, as shown on page 3. Contact the factory for more information.

6. To meet the requirements of EN 61000-4-5 ( 2 kV), external components are

needed. This can be done discretely as shown on page 3. Contact the factory for

more information.

7. These units should not be operated with a load under 5% of full load. Operation

at no-load will not damage the unit, but they may not meet all speciﬁcations.

8. 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.

of 25%.

3. Short circuit protection is provided by a “hiccup mode” circuit.

4. All units are rated for EN 55022 (CE/RE) class A without external components.They

will meet class B with the addition of the discrete ﬁlter circuit as shown on page 3.

Contact the factory for more information.

The diagram below illustrates a typical connection of the MA300SERU series for

applications that require meeting EMC standards. The units do not require external

components to operate as speciﬁed. Some notes on this diagram (starting with the

input circuit) are:

1. It is recommended that an external fuse be used.The recommended fuse is shown

in the model chart on page 2.

Derating Curve

2. An external MOV is recommended on the input to protect the unit in the event of

a surge. A recommended value is given in the table at below.

3. The output ﬁltering capacitor (C⁴) is a low ESR electrolytic capacitor. Care must be

taken in choosing this capacitor not to exceed the capacitive load speciﬁcation for

the unit. Voltage derating of capacitors should be 80% or above.

4. Recommended values for components are:

5. The“Typical Board Layout”drawing shows a suggested board layout for the EMC/

EMI circuit. Filtering capacitor (C4) is a low ESR resistance electrolytic capacitor.

Care must be taken in choosing this capacitor not to exceed the capacitive load

speciﬁcation for the unit.

6. In many applications simply adding input/output capacitors will enhance

the input surge protection and reduce output ripple sufﬁciently. Typically,

the value of the input capacitor should be 10 µF to 47 µF. The recom-

mended output capacitor would be 10 µF. A typical board layout for this

connection is shown at the bottom of this page.
