Description

The GS1T70-D540Fconverter has been designed for the "U" interface of an ISDN-NTBA (Network Termination BasicAccess) systemwith either 4B3T or 2B1Qstandard trasmission.

GS1T70-D540F meets the requirements of the following specifications:EN 60950  CCITT I.430,CCITT G.960,CCITT G.961,ETS 300 002,ETS 300 012,ETS 300 047 (ISDN BASIC ACCESS, Safety and Protection)

Two isolated outputs, 5V/90mA and 40V/10.5mA are supplied.The converter GS1T70-D540F offers short-circuit protection (short circuit on 40V output doesn't affect 5V output and the input power never exceeds thelimit of the specification), input either voltage polarity, 80%minimumefficiency atmaximum load, input and output filtering to meet very stringent noise requirements.
