12V 50A High Load Relay BS4 12S C20 Electric Control Device Load Relay
12V 50A Relay Introduce:
The relay is an electric control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity (excitation quantity) meets the specified requirements. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in automatic control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.
12V 50A Relay Features:
Sensitivity: When a metallic short circuit occurs within the protected range of equipment or lines, the protection device should have the necessary sensitivity coefficient. Guaranteed to be removed if there is a fault.
