GS5AC-40 ISDN AC-DC CONVERTER PRELIMINARY DATA Type GS5AC-40 Vi 180 to 264 V Vo Io out 1: 40 V 110 mA out 2: 40 V 10 mA FEATURES Large Input voltage range: 180 to 264 VRMS Input filter to meet EMI requirements Peak input overvoltage whitstanding Input fuse Input to output insulation 2 insulated outputs: Vo1 = 35 to 42 V for ”S” interface Vo2 = 36 to 47 V for external relay and LED driver ”S” interface output characteristics: Peak output of 8 W for 150 ms Typical output power: 4,5 W Output filtering to meet ETSI requirements Hold up time: 20 ms with 4,5 W output power Continuous short circuit protection Peak overvoltage withstand: 250 V for 10/700 µs Mechanical dimensions (LxWxH): 80x43x30 mm 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 is able to deliver 40V/110 mA for ”S” interface and is equipped also with a second, auxiliary 40V/10 mA output for relay and LED driving. The converter 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 allowing the use of a second 20 January 1997 ”emergency” voltage source (relay contacts are released). 3000 VRMS insulation voltage for 60 seconds is provided between input and the outputs. 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), 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. 1/4 GS5AC-40 ELECTRICAL CHARACTERISTICS (Tamb = 25°C unless otherwise specified) Std.
