● Units for single phase and three phase coupling
● Extended current / voltage range to 30A / 440Vac
● Combined surge / burst coupling
These external coupling networks extend
the range of surge and burst generators
to higher currents and voltages, three
phase applications and system
installations with a common EUT
connection.
The basic models, CDN 131 for single
phase and CDN 133 for three phase
applications, precisely match the type
2050 test system with its range of surge
generator modules.
A burst coupling option, CDN 151 for
single phase or CDN 153 for three phase
applications, can be fitted into the unit to
provide higher current burst test
possibilities for the System 2050.
These options also build a system
solution with a single, common EUT
connection when separate surge and
burst generators are used.
The specifications of the EUT path are
pushed to 30A per phase and a AC
voltage of up to 440V (phase to phase).
The decoupling inductors are designed to
tolerate the high inrush currents often
encountered in high power and three
phase test installations. The couplers are
entirely controlled by the pulse generator
and perform their coupling modes under
local control or under control of the
Windows application program associated
with the pulse generator.
Power to the EUT is internally controlled
and can be switched on and off at any
time by the operator or may be set under
program control. The units fully comply
with the relevant standards such as
IEC 61000-4-5, ANSI-IEEE C 62.45,
IEC 61000-4-4, etc. The coupling
methods exceed the requirement of the
standards and effectively allow for all
possible combinations of differential
couplings, common mode and line(s) to
ground coupling combinations.
Special attention has been paid to an
overall safe operation.
An interlock circuit prevents high voltage
pulses being generated as long as the
protection line is not closed.
An overcurrent trip switch protects the
EUT. Various connector panels are
provided to ensure correct industrial
wiring of the EUT.
CDN 131
Single phase coupling network for surge
type pulses with 240V/30A ac capability.
An optional CDN 151 single phase burst
coupling section can be built in.
CDN 133
Three phase surge coupling network for
EUT's up to 440V/30A per phase.
The CDN 153 three phase burst coupling
option extends the unit into a combined
coupler with a single, common EUT
interface.
CDN 135
Special version to be used with the
BESTplus and BESTemc generator.
It includes three phase surge and burst
coupling capabilities as a standard.
