for Switch Mode Units
The number of options per module may be restricted due to limitation of space inside the module or due to a limited number of
connector pins. Potentiometers or interface cards may be supplied separately for installation outside of the module.
General information
pr input voltage supervision (power ok) incl. relay contacts
A logic signal is given if the input voltage (AC or DC) drops below the specified limit. In
AC input models the rectified input voltage is sensed so that a power fail alarm can be
avoided if at light load mains power returns before the input capacitors are substantially
discharged. A relay contact is provided for failure indication.
dr output voltage supervision (DC ok) incl. relay contacts
A logic signal is given if the output voltage is below the specified limit. A relay contact is
provided for failure indication.
DC ok level: 5V output: 4,75V
all other voltages: 90% of adjusted voltage
cf charger / converter fail supervision incl. relay contacts
A logic signal is given if the input voltage, the auxiliary voltage of the primary side and
the current of the primary side exceed or go below a specified range. A relay contact is
provided for failure indication.
ac AC ok for inverter including relay contacts
A logic signal is given if the output voltage of an inverter is below the specified limit. A
relay contact is provided for failure indication.
