Positive input voltage. Unregulated input voltage (typically 48V) must be applied between pin 1-2. The converter is ON (Enable) when the voltage applied to this pin with reference to pin 1 is lower than 1.2V (see Vien). The converter is OFF (Inhibit) for a control voltage in the range of 8 to 18V. When the pin is unconnected the converter is OFF (Inhibit). Case connection pin. Synchronization pin. See figures 3, 4, 5, 6. Open when not used. Parallel output. See figures 3, 4, 5, 6. Open when not used. Senses the remote load high side. To be connected to pin 11,12 when remote sense is not used. Senses the remote load return. To be connected to pin 9,10 when remote sense is not used. In parallel configuration, take care to connect all -S pins together (see figures 3,4,5,6). Fixed output voltage return. Fixed output voltage. Description GS120/175T48 FAMILY USER NOTES Reflected Input Current The reflected input current measurement (lir, see Electrical Characteristics) is performed according to the test set-up of fig. 2. Figure 2. Softstart To avoid heavy inrush current the output voltage rise time is 10ms maximum in any condition of load. Remote Sensing The remote voltage sense compensation range is for a total drop of 0.6V equally shared between the load connecting wires. It is a good practice to shield the sensing wires to avoid oscillations. See the connection diagram on figures 3, 4, 5, 6. Remote ON/OFF The module is controlled by the voltage applied between the ON/OFF pin and -IN pin. The converter is ON (Enable) when the voltage applied is lower than 1.2 V (see Vien on Electrical Characteristics). The converter is OFF (Inhibit) for a control voltage in the range of 8 to 18V (see Viinh). When the pin is unconnectedthe converter is OFF. Maximum sinking current is 1mA. Module Protection The module is protected against occasional and permanent shortcircuits of the output pins to ground, as well as against output current overload. It uses a current limiting protection circuitry, avoiding latch-up problems with certain type of loads. A crowbar output overvoltage protectionis activated when the output voltage exceeds the specified values (see Electrical Characteristics). Parallel Operation To increase available output regulated power, the module features the parallel connection possibility with equal current sharing and maximum deviation of 10% (two modules in parallel). See the connection diagram on figures 3, 4, 5, 6. 7/10 GS120/175T48 FAMILY Figure 3. Figure 4. Figure 5. Figure 6. Finned heatsink option An additional finned heatsink is available (type ordering number HS01) to allow the user to decrease the total thermal resistance of the module to a typical value of 2.8 °C/W. The heatsink is suitable both for standard (4-40 UNC threading) and E version (M3 threading); screw length in the range of 6 to 8 mm (0.24 to 0.32”).
