DC Monitoring Module DC-ÜM 22
DC-monitoring module
DC-ÜM 22
up to 20 A output current
DIN rail module to build up a battery-
buffered, monitored 24 V/DC power
supply system.
The output voltage of a 24 V power
pack which must be set to 27.6V
(charging voltage of the battery) and a
lead-gel battery are connected to this
module.
The total of load current and charging
current may be 20A maximum, the
load current being the difference
between the current available from
the power pack and the supply current.
The DC-ÜM 22 is equipped with a
battery fuse which protects battery
and battery cable from reverse
polarity. Mains- and battery mode are
signalled via LEDs.
A mains error message or a U-min
message (if the battery voltage is less
than 22V) is available as potential-free
change-over contacts.
The message is selected by means of
jumpers. The battery is disconnected
automatically at appr. 19 V before the
full discharge protection theshold is
reached.
Of course we can also supply
corresponding power packs and
batteries.
Error messages
alternatively (jumper) power failure or
U-min message (potential-free
contacts)
