Figures17 and18 showthattheremainingvoltage
doesnot exceed270V.
Consequently,the CLP200Mtotallyfulfills thistest.
The test duration is not specified in test 3b. If the
duration exceeds 5s we do suggest to follow the
soldering and mounting recommendations given
on page 17 of this document.
3.2.3Powercontact(Test 3 table1/K20)
This long duration surge is produced when con-
necting a subscriber line to an AC mains line or
equipment.The purposeof thistestis tocheckthe
robustnessof theCLP200M against these distur-
bances.
The test 3 of CCITT K20 requires a serial PTC (or
fuse)which is insertedin thetest circuit to limit the
currentrate. ThisPTC actslikean open-circuitin a
non-instantaneous way when a surge occurs on
the line. Meanwhile, the CLP200M has to with-
standthe surge.
Figure 20 shows that the remaining overvoltage
does not exceed 250 V and shows that the PTC
actslike an open-circuitafter 60 ms.
Consequently,the CLP200Mtotallyfulfillsthistest.
