Portfolio:
1-/2-phase 24V/ 5A and 10A 1-phase 24V/ 20A and 40A 3-phase 24V/ 20A and 40A 3-phase 48V/ 20A
Extremely robust Metal housing and reliable DIN
rail mounting with metal clip
Minimum space requirements
Reduced installation efforts Primary and secondary
terminals are on the same level Potentiometer for voltage
adjustment is integrated in front of the unit
IMPORTANT: no additional mounting width needed !!

Basic Units
Wide input voltage range
Adjustable output voltage up to + 20%
Adjustable reaction to short circuits Shutoff with storage or automatic restart
U/I-characteristic curve with power boost to supply up to 300% of the rated output current
Switch-selectable for parallel operation
Easy understandable display of operating status with 3 LEDs Green: output voltage > 20V
In case of failure when used in parallel operation there is no LED signal from the broken device!
Yellow: output voltage < 20VSignalizes overload in operating mode „automatic restart“
Red: shutoff with storage or remote shutoff In order to avoid confusion there is only one LED signal at the same
time !

For brief power failures up to3 seconds
800 msec at 5A load current 100 msec at 40A load current Can be used in parallel connection
to increase hold up time needs
The buffer module supplies the precise output voltage to which the basic unit is set with a tolerance of minus 1V.
In case of temporary increased power demands the module supplies up to 40A in addition to thepower boost of 60A with the 20A &120A with the 40A power supply)
