Temperature Control Signal (TEMP)
The power supply has a temperature monitor. Here, the temperature of the power supply is continuously
measured. The signal TEMP provides a voltage U
TEMP
corresponding to the internal temperature of the power
supply T
INT
: T

in mV. Measuring range: +2...+150°C. Output impedance 2kOhm.
Between the signal TEMP and the power input and the power output is a reinforced Isolation max. 400Vdc.
Temperature Warning (TA)
The power supply has a Temperature Warning. The signal provides the user the option to save important data
before the power supply shut down from OT, or to put his system in the emergency mode. The alarm signal TA
is high when the internal temperature of the power supply is approximately 5°C below the overtemperature
protection threshold. Output Open Collector I

Over Temperature Shutdown (OT)
The alarm signal OT is high when the temperature of the power supply is higher than the over-temperature
protection threshold. Output Open Collector I

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 always linear proportional to the control signal
Ureg.
The desired control signal is selected via the DIP switcher:
0-5V, 0-10V, 0-20mA oder 4-20mA.

Inrush Current Limiter (electronic)
The power supply unit has an electronic current limiter
(230Vac=14,6A

).
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.
