40A Power Relay Applied To Electric Vehicle Power Supply Equipment NB90-12S-S-C
40A Power Relay Description:
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.

40A Power Relay Introduce:
Relays generally have induction mechanisms that can reflect certain input variables (such as current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc.); Actuator; between the input part and the output part of the relay, there is an intermediate mechanism that couples and isolates the input quantity, processes the function and drives the output part.
