1. To meet the requirements of EN 61000-
Radiated Emissions EN 55022 Class B 4-4 (±4 kV), external components are
Conducted Emissions EN 55022 Class B needed. This can be done discretely (as
±8 kV Air shown below), or with the addition of the
ESD EN 61000-4-2 B MACFM-02A. Contact the factory for more

2. To meet the requirements of EN 61000-4-5
B ±2 kV (±2 kV/ ±4 kV ), external components are
EFT, See Note 1 EN 61000-4-4
B ±4 kV needed. This can be done discretely (as
B ±1 kV/±2 kV shown below), or with the addition of the

Typical Connection: With Input Protection/Filtering Components













The diagram above illustrates a typical connection of the MPM-05SV series. 5. Suggested component values are:
The input components are required to meet the more stringent EFT/Surge levels
Component MPM-05MS-05 MPM-05MS-12 MPM-05SV-15 MPM-05MS-24
of EN 61000-4 (see notes for EMC Characteristics table above). Some notes on
these components are: Fuse 2.0A/250 VAC 2.0A/250 VAC 2.0A/250 VAC 2.0A/250 VAC
1. It is recommended that an external fuse be used. The recommended fuse MOV S14K300 S14K300 S14K300 S14K300
size is a 1.0A/300 VAC slow blow.
CX 0.1 µF/275V 0.1 µF/250V 0.1 µF/250V 0.1 µF/250V
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 right. LDM 4.7 µH/2A 4.7 µH/2A 4.7 µH/2A 4.7 µH/2A
3. The output fi ltering capacitors (C1 & C2) will reduce the output noise below LCM 2.2 mH 2.2 mH 2.2 mH 2.2 mH
specifi ed levels. Recommended values are given in the table on page 2.
4. Input protection and fi ltering modules are available for a number of MPD CY1/CY2 1.0 nF/400 VAC 1.0 nF/400 VAC 1.0 nF/400 VAC 1.0 nF/400 VAC
AC/DC power supplies. For use with the MPM-05MS product series, the NTC 5D-9 5D-9 5D-9 5D-9
MACFM-02A fi lter module is recommended. A typical connection diagram
and board layout with this module is shown in the fi gures below. For pricing
or full technical information on the MACFM-02A (or any of our other modules)
please contact the factory.

Typical Board Layout: With External Filter Module













1. The width of circuit traces should be a minimum of 3 mm.
2. The distance between traces should be a minimum of 6 mm.
3. The distance between a trace and ground should be a minimum of 6 mm.
