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 converter GS5AC-40 is able to deliver 40V/110mA for "S"interface and is equipped also with a second, auxiliary 40V/10 mA output for relay and LED driving. The converter GS5AC-40 offers short-circuit protection on both 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 GS5AC-40 allowing the use of a second"emergency" voltage source (relay contacts are released). 3000 VRMS insulation voltage for 60 seconds is provided between inputand the outputs. Output 1 and Output 2 share the same common ground (pin 4 is internally connected with pin 6).

The design of the GS5AC-40 has been conducted using, as reference standards, the following:EN 60950, VDE0878 part 1 class B (EMC), EN55022 class B (EMC), CCITT 430, ETS 300 012 and ETS 300 047 (ISDN BASIC ACCESS, Safety and Protection); anyway, please note that no certification processes have been carried out on the module itself.
