Fan Fail Signal (FF)
The power supply fans are continuously monitored. FF occurs when one or both fans have an error (lower
speed due to bearing contamination, blockage, or failures). A failure message is sent: The status signal FF
applies high. Output Open Collector I

C/V Chart and Operating Point
The output voltage set Vout is set with the potentiometer at the rear oft he power
supply.
The current limit is fix.
The system integrator must make sure that the nominal output power does not
exceed below values to protect the unit from operating under overload conditions.

Inrush Current Limiter (electronic)
The power supply unit has an electronic current limiter
(230Vac=14,6A
rms
/20,7A
peak
).
It is a precisely working circuit instead of a usual simple NTC
solution. The accuracy is ±10%, regardless of the operating
temperature and the duty cycles (interval
≥
10s). We recommend
the smallest circuit breaker a characteristic B with 16A.
Temperature Monitoring & Derating
The maximum ambient temperature during operation is + 60°C. If the
overtemperature protection is activated, the power supply but not the fan is
switched off.
The measuring point is 50mm outside the power supply at the front side
(fan/blower input). The power supply unit starts automatically when it has
cooled down.
