12V/24V Deceleration Motor Starter Relay 150A High Power Car Motor Start Relay

Product function: increase the current of the starter and help the starter startInstallation method: two feet are connected to the iron, the upper screw is connected to the electric door lock. The two columns are connected to the power supply.Start relayThe function of the starter relay is that when the starter motor is working, a large current is required. The key is used to control the starter motor. When the key is turned on, if a large current flows from the key to the starter, the key must be made large and Bulk, able to withstand the frequent passage of large currents without burning, and the use of very thick wires to connect the battery, the key and the starter motor, it is not cost-effective, the use is not reliable, and the maintenance is not convenient.People invented the starter relay, so that the starting current from the battery directly to the starter motor through the relay, at the same time, must accept the control of the key. The control current through the key is very small, the line is also very thin, increasing the life of the key.The starter relay is controlled by the keyWhen the key is turned on, the suction coil in the starting relay is energized to generate suction, and the starting circuit contacts are sucked, so that the current reaches the starting motor through the starting relay, and the starting motor works;When the key is disconnected, the suction coil in the starting relay is de-energized, the suction force disappears, the starting circuit contact is disconnected under the action of the spring, the current to the starting motor is cut off, and the motor stops working.
