Automotive relays are essential components for many automotive electronics systems. The JJM1A-12V is a dual-supply, double-action, power control relay, specifically designed for automotive applications. It provides high-current switching up to 160A with the advantage of low on-resistance and long operating life.
Application Field
The JJM1A-12V is an ideal choice for automotive electronic applications such as a starter, charge and discharge circuits, and motor drives. Its compact design with double-actions and power saving features make it suitable for many applications. It has a maximum switching current of 160A which makes it suitable for high-current switches needed in starter and engine control systems. It is also fit for high-current charging and discharging circuits of electric vehicles.
Working Principle
The JJM1A-12V has a double-action mechanism. When the voltage is lower than the set value, the contact is open and the circuit is cut off. When the voltage reaches the preset value, the contact is closed, the output is connected, and the current passes. The JC-12V is equipped with dual power supplies, which makes it more stable and can control larger current. It also has an automatic connection and disconnection feature. When the set current is exceeded, the switch automatically disconnects the output, thus preventing further damage.
Finally, the JJM1A-12V has reverse-current protection to prevent damage due to over-current or short-circuiting. In addition, it has an adjustable output voltage, which means the current is adjustable and can be adjusted to different levels for different applications.
To sum up, the JJM1A-12V is a very reliable automotive relay that can be used in various automotive electrical systems. It has the ability to control high-current, is compact, has low on-resistance, and is highly durable. It is a great choice for many automotive applications.
