The Carlo Gavazzi DPA52 Series monitoring relay is suitable for 3-phase monitoring without neutral mains and protects loads from wrong phase sequence and phase loss. It detects phase loss also with regenerated voltage presence. DPA52 doesn’t require any setting or adjustment and is ready for operation once installed.
The DPA52 has a switching power supply which makes it wide range (125 to 624VAC) and immune to mains disturbances, transients and harmonics problems. Additional protection against dust and humidity is provided by the PCB conformal coating.
