DC Fail Signal (DCF)
DCF is high when the power output is disabled by SB, INH, ACF, OT, FF or OVP. While SD is active the
message signal DCF is low. Output Open Collector I
MAX
=10mA, V
LOW
≤
0,6V, V
MAX
=30V.
AC-OK Relay (AC Power Good)
The Power Good relay reports whether the input voltage is too low or missing. The notification signal AC OK is
generated with potential-free relay contacts (changeover).
The contacts of CON1 Pin1 and CON1 Pin3 are closed (relay coil is energized) when the input voltage is higher
than typ. 175Vac or 210Vdc (switch-on). The contacts of CON1 Pin5 and CON1 Pin3 are closed (relay coil is
not energized) when the input voltage is lower than typical 165Vac or 145Vdc (turn-off). Contact load (resistive
load): 30Vdc/1A, 60Vdc/0.3A, 30Vac/0.5A.
Between the relay contacts and the power input, and the output power is a reinforced isolation max. 400Vdc.
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.
Output Open Collector I
MAX
=10mA, V
LOW
≤
0,6V, V
MAX
=30V.
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 or a defective PFC occur the message
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 voltage source. Output Open Collector
I
MAX
=10mA, V
LOW
≤
0,6V, V
MAX
=30V. When OVP, INH, SB, SD, FF, OCP or defective PFC occur the message
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 on and off 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.
