EMC Speciﬁcations

Notes:

Parameter

Standard

See Note 1

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

They will meet class B with the addition of the MDCFM-02A(W) (or a similar

discrete ﬁlter circuit). Contact the factory for more information.

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

are needed.This can be done discretely, or with the addition of the MDCFM-

02A(W). Contact the factory for more information.

The diagram above illustrates a typical connection of the MB1500ERU

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.

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.

3. An external TVS is recommended on the input to protect the unit in the

event of a voltage spike. A recommended value is given in the table at

right.

4. The output ﬁltering capacitor (C³) is a high frequency, low resistance

electrolytic capacitor. Care must be taken in choosing this capacitor not

to exceed the capacitive load speciﬁcation for the unit. The board layout

illustrationbelowshowsaconnectionfordualoutputunits.Voltagederating

of capacitors should be 80% or above.
