FEATURES High input voltage range bus: 200 to 400Vdc UL, TUV approved High output power (up to 100W) High efficiency (80% min. on GS100T300-5 module) Output voltages range: 3.5-5.2-12-15-24and 48V Output voltage adjustable by external pin Remote load voltage sense compensation Output short-circuit protection Output overvoltage protection Undervoltage lock-out Minimal overshoot during load transients 3750VRMS input to output isolation voltage Internal input and output filtering Softstart PCB or chassis mountable Mechanical Dimensions 101,6 * 50,8 * 20 mm (4,00 * 2,00 * 0,79 inches)
DESCRIPTION The GS70/100T300 family includes 70/100W DCDC converters used to generate isolated output voltages with an output current up to 20A from a wide range input voltage (200 to 400Vdc). All the GS70/10 0T300 family modules require an external fuse (1 Amps.) on the input side.

Package R; dimensions in mm (inches) PIN DESCRIPTION
Pin 1 2 3 4,5 6,7 8 9 10 8/10 Function ENABLE - Vin + Vin + Vo - Vo + SENSE - SENSE ADJ Description The converter is ON (Enable) when the voltage applied to this pin with reference to pin 2 is lower than 1.2V. The converter is OFF (Inhibit) for a control voltage in the range of 2.1 to 5V. When the pin is unconnected the converter is OFF (Inhibit). Negative input voltage. Positive input voltage. Unregulated input voltage in the range of 200 to 400Vdc must be applied between pin 2-3. +Vo output voltage. +Vo output voltage return. Senses the remote load high side. To be connected to pins 4,5 when remote sense is not used. Senses the remote load return. To be connected to pins 6,7 when remote sense is not used. Adjust output voltage pin. A voltage generator between the ADJ. pin and -SENSE pin sets the Vo. When unconnected Vo is at nominal value (see fig. 2).
