DESCRIPTION

The GS5AC-40 converter has been designed for
an ISDN-NTBA (Network Termination Basic Ac­cess) system with either 4B3T or 2B1Q standard
trasmission.

The converteris able to deliver 40V/110mA for ”S”
interface and is equipped also with asecond, aux­iliary 40V/10 mA output for relay and LED driving.
The converteroffersshort-circuit protection onboth
outputs (short-circuit on 40V output doesn’t affect
relay/LED output and the input power never ex­ceeds the limit of 15 W) and also provides to
remove the auxiliary(relay &LED) output when the
mains is missing,thus allowingthe useof a second

”emergency” voltage source (relay contacts are
released). 3000 V

insulation voltage for 60

RMS

secondsisprovided betweeninputandtheoutputs.
Output 1 and Output 2 share the same common
ground (pin 4 is internally connected with pin 6).

The design of the module has been conducted
using,as reference standards, the following:

EN 60950, VDE0878 part 1 class B (EMC),
EN55022classB (EMC), CCITT 430, ETS300012
and ETS 300 047 (ISDN BASIC ACCESS, Safety
and Protection);anyway,pleasenote that no certi­fication processes have been carried out on the
moduleitself.
