Enclosure class IP 23 IP 23
Application class
1) Valid for power sources without VRD specification on the rating plate.
2) Valid for power sources with VRD specification on the rating plate. The VRD function is explained in
the instruction manual for the control panel.
Mains supply, Z
max
Maximum permissible line impedance of the network in accordance with IEC 61000-3-11.
Duty cycle
The duty cycle refers to the time as a percentage of a ten-minute period that you can weld or cut at
a certain load without overloading. The duty cycle is valid for 40° C.
Enclosure class
The IP code indicates the enclosure class, i. e. the degree of protection against penetration by solid
objects or water. Equipment marked IP23 is designed for indoor and outdoor use.
Application class
The symbol indicates that the power source is designed for use in areas with increased
electrical hazard.
