Ambient temperature (°C)
*1 The available output current varies depending on the ambient operating temperature. Use the FX
20PSU in the available range in accordance with the output derating graph shown above.
*2 If the output current flows beyond the specified value, the overcurrent protection circuit is actuated
and the output voltage drops.
When the overcurrent status or the short-circuit status returns to acceptable levels, the output voltage
automatically recovers.
*3 If the voltage beyond the specified value is generated by an internal failure, etc., the output is shut
down so that high voltage is not output. When the voltage comes from a load circuit connected to an
output terminal or when overvoltage is input from the outside, the overvoltage protection circuit may
be actuated.
When the overvoltage protection circuit is actuated, the output is shut down and does not automati-
cally recover. Ask for inspection and repair after such an occurance.
