Enclosure class IP 23
Application class
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/104°F, or below.
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 intended for indoor and outdoor use.
Application class
The symbol indicates that the power source is designed for use in areas with increased electrical
hazard.
3.1 ECO design information
The equipment has been designed in order to be compliant with the Directive 2009/125/EC and the
Regulation 2019/1784/EU.
Efficiency and idle power consumption:
Name Idle power Efficency when max power
consumption
EM201C 36W 87%
EM203C 20W 86%
EM251C 43W 84%
EM523C 20W 89%
The value of efficiency and consumption in idle state have been measured by method and conditions
defined in the product standard EN 60974-1.
