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 cha-
racteristics of this converter which is ideal for highly sophisticated industrial designs.The
RS3 is available with 2kV or 3kV isolation options (1kVDC is standard)

Maximum capacitive load is defined as the capacitive load that will allow start up in under 1 second without damage to the converter
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.
