AC Fail Signal (ACF)
The alarm signal ACF is high when the input voltage is lower than typ. 165Vac or 145Vdc.
The alarm signal ACF is low when the input voltage is higher than typ. 175Vac or 210Vdc.

Over Voltage Protection Signal (OVP)
If an over-voltage occurs to the output (for example, defective components, external feed voltage), it is followed
by the shutdown of the power output. A periodic restart attempts (ticker operation period 1s) and a message is
triggered: The alarm signal OVP is high. Output Open Collector I
MAX
=10mA, V
LOW
≤
0,6V, V
MAX
=30V.
Constant Voltage Mode (CV)
The signal CV is high when the power supply operates as a constant voltage source. Output Open Collector
I
MAX
=10mA, V
LOW
≤
0,6V, V
MAX
=30V. When OVP, INH, SB, SD, FF, OCP, OT or a defective PFC occur the mes-
sage signal CV is low because the power output is switched off. The change between the CV and the CC mode
is automatic. Please pay attention to the DIP switch setting of the Fuse Mode to avoid provoking malfunction.
Constant Current Mode (CC)
The signal CC is high when the power supply operates as a constant current source. Output Open Collector
I
MAX
=10mA, V
LOW
≤
0,6V, V
MAX
=30V. When OVP, INH, SB, SD, FF, OCP, OT or defective PFC occur the mes-
sage signal CC is low because the power output is switched off. The change between the CV and the CC mode
is automatic. Please pay attention to the DIP switch setting of the Fuse Mode to avoid provoking malfunction.
CC-Mode & Over Current Protection in the Fuse Mode (OCP)
The alarm signal OCP is high, when the constant current
operation appears for more than typical 5s (Fuse Mode
DIP switch S12=0).
Output Open Collector I
MAX
=10mA, V
LOW
≤
0,6V, V
MAX
=30V.
By switching the unit off and on from SB, SD, or the mains,
the power supply returns into operation.
The power output is switched off. The PFC and the fans
are not switched off. In the SB or SD mode the message
signal OCP is low. In the INH mode the status of the power
supply does not change.
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

TEMP
/(10mV/°C), U

in mV. Measuring range: +2...+150°C. Output impedance 2kOhm.
Between the signal TEMP and the power output is a reinforced Isolation of max. 400Vdc and a basic isolation
of max. 600Vdc working voltage.
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
MAX
=10mA, V
LOW

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
