Individual Calibration

Two Year Warranty

Description

The M series powerline Coupling / Decoupling Net-

works (CDN) are for testing from 150 kHz - 80 MHz

according to the EN 61000-4-6 standard for immunity

to conducted disturbance induced by radio frequency

fields. The standard M series CDNs are available with

25 amperes current rating.

The coupling network delivers injected common mode

current disturbance signals through the power line con-

ductors to the equipment under test (EUT). The

decoupling networks are used to ensure that the dis-

turbing signals injected on the powerline of the EUT

by the coupling networks do not interfere with any of

the auxiliary equipment connected to the EUT. Each

CDN contains integrated direct capacitive coupling

along with a high impedance choke for inductive

decoupling.

All CDNs are individually calibrated to meet the im-

pedance requirement of EN 61000-4-6. However, test

level calibration must be performed on site to deter-

mine the minimum required test signal needed to

achieve the required voltage levels specified by EN

61000-4-6. The appropriate calibration accessories for

conducting the test is available from Com-Power.

Application

During the test, the CDN is connected to the powerline

cables between the equipment under test (EUT) and

auxiliary equipment (AE). The number of conductors

in the cable will determine which CDN to use for the

test.

The M125 CDN is used to couple common mode and

modulated signals onto single power line systems. This

CDN is ideal for electronic systems that uses the chas-

sis as the DC return. The M225 CDN is for systems

with two wire power conductor cables without an earth

terminals and the M325 is for single phase two line

cables with the an earth ground conductor. The M425

is used for three phase systems. The M525 CDN is used

for three phase systems with neutral and protected earth

ground conductors. All CDNs are also fitted with safety

sockets for connecting the devices under test.
