12V 50A Relay Description:
Relays are new energy products like electric vehicles, which must be the trend in the next few days. Therefore, more and more fast charging stations are manufactured to meet the needs of electric vehicle charging. NB90 series AC relays are specially used in charging piles. The contacts have high breaking capacity, dust-proof or sealed types are optional, and are environmentally friendly.
12V 50A Relay Features:
1. Speed: It means that the protection device should be able to cut off the short-circuit fault as soon as possible. Its purpose is to improve system stability, reduce the damage of faulty equipment and lines, reduce the scope of faults, improve the effect of automatic reclosing and backup power supply or automatic input of backup equipment, etc.;
2. 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;
3. Selectivity: It means that the protection of the faulty equipment or the line itself should remove the fault first, and only when the protection of the faulty equipment or the line itself or the circuit breaker refuses to operate, the fault can be removed by the protection of the adjacent equipment, the line or the protection of the circuit breaker failure.
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.
