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)

Note: To protect the converter under all fault conditions, an input fuse is required. Quick-blow fuses
should be rated at 2x-3x the normal input current, time-delay fuses at 1.5x the normal input current.
Notes
Note 1:
Note 2:
Maximum capacitive load is defined as the capacitive load that will allow start up in under 1 second without damage to the converter
The RS3 series requires a minimum of 10% load on the output to maintain specified regulation. Operating under no-load conditions
will not damage these devices; however, they may not meet all listed specifications.

Pin 8 (NC*)
This pin is used internally and must have no external connection.
Pin 5 (NC)
Not connected internally.
Pin 3 (CTRL)
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 high ‘Z’ the converter is ON.
There is no allowed low state for this pin.
