Coil Latching Relay Be Able To Bear 750A Short-Circuit Inrush Current
DC RELAY coil goes through the DC (U or I), resulting in a constant magnetic field, the power loss is only caused by the heat of the coil. Since the current is constant, the flux is constant and the attraction is constant, so there is no trembling phenomenon, unless the coil voltage fluctuates significantly.
The coil of AC RELAY goes through the AC, resulting in a changed magnetic field (the main flux, leakage flux).
In addition to the coil resistance itself, the heat loss (copper loss), the AC coil also has iron loss (including hysteresis loss, eddy current loss).
AC-RELAY current is alternating, which results that the magnetic flux is also alternating, and the attraction is also changing. So AC-RELAY will have 'hissing' sound. If the voltage fluctuates, the relay will continue to open and close.
