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.
