Very high power density, 2:1 or 3:1 input voltage range and a wide operating temperature range -40°C~+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)

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.
