Electromotive force of power supply in relay protection
This back electromotive force (EMF) can damage the power supply's output stage. Protective relays and devices have been developed over 100 years ago to provide “lastline”of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. The magnetic field collapses when the. Use of relay contact protective devices or protection circuits for an inductive load can suppress the counter EMF (electromotive force or electromagnetic field) to a low level. However, note that incorrect use will result in an adverse effect. OMRON relays are used in a wide variety of products by our customers, and there are a wide range of design considerations, such as counter electromotive voltage of coils, holding.
