GS1T70-D540 - ISDN DC-DC CONVERTER

General Description

The GS1T70-D540/2 converter has been designed for the “U” interface of an ISDN-NTBA (Network Termination Basic Access) system with either 4B3T or 2B1Q standard trasmission.

Two outputs, 5V/72mA and 40V/12mA are supplied.

Key Features

  • Wide operating line termination voltage Positive or negative input voltage polarity Input and output filtering Short-circuit protection on both outputs Input power during shortcircuit within specification Minimum current drain during stand-by condition: 10µA for Vi.
