Division 1 Energy efficiency requirements
United Kingdom
From 1 January 2023, the power source efficiency of welding equipment, shall not be lower than the values set out in Table 1, and the idle state power consumption shall not exceed the values set out in Table 1.
Table 1
Power source efficiency and idle state power consumption
| Minimum power source efficiency | Maximum idle state power consumption | |
|---|---|---|
| Welding equipment powered by three-phase power sources with direct current (DC) output | 85 % | 50 W |
| Welding equipment powered by single-phase power sources with direct current (DC) output | 80 % | 50 W |
| Welding equipment powered by single-phase and three-phase power sources with alternating current (AC) output | 80 % | 50 W |
Compliance with the ecodesign requirements on power source efficiency and idle state power consumption shall be assessed, measured and calculated in accordance with the methods set out in Annex III.
