The PFU6 electronic monitoring relay enables welding transformers to be monitored in accordance with VDE 0545. Hazardous contact voltages / insulation faults are monitored on six measuring circuits. For example, up to six secondary windings on welding transformers can be independently monitored for hazardous voltages, through a single unit.
Its 45 mm housing is designed for a rugged industrial environment, ensuring the PFU6 provides a space-saving solution for the safety of personnel on resistance welding plants, which are used in the automotive industry for example.
