DC/DC Converter
RS3-S(D)(Z)
Very high power density, 2:1 or 3:1 input voltage range and a wide operating temperature range
-40°C to +71°C and extra features such as On/Off control are just some of the characteristics of this
converter which is ideal for highly sophisticated industrial designs. The RS3 is available with 2kV or 3kV
isolation options (1kVDC is standard).

Notes:
Note5: For repeat Hi-Pot testing, reduce the time and/or the test voltage
Note6: To protect the converter under all fault conditions, an input fuse is required. Quick-fuses should be rated at 2x-3x the
nominal input current, time -delay fuses at 1.5x the nominal input current

This pin provides an Off function which puts the converter into a low power mode. When the pin is ‘high’ the converter is OFF and when
the pin is open the converter is ON. There is no allowed low state for this pin. (refer to „ON/OFF CTRL“ on page 3)
This pin is used internally. No external connection allowed
