JS1AF-B-12V

Power relays rated greater than 2 amperes usually have an appreciable physical size and a significant inrush current when energized. Therefore, they must be protected to prevent fire or damage to connected circuits. The JS1AF-B-12V is a relay used to protect devices which require switching of high currents and are susceptible to current surges. It is typically used for high power applications including in telecommunication systems, solid-state drives, and electric vehicles.

The JS1AF-B-12V is a single-pole, double throw (SPDT) type power relay with a rated current of 12 volts. The relay has a maximum flux density of 0.6 mT and a switching power rating of up to 20 amperes. The actual power rating of the relay is dependent on coil voltage, operating temperature, mounting hole dimensions, and the direction in which load connection is made. It has a mechanical life of up to 50,000 operations.

The working principle of the JS1AF-B-12V is based on an electromagnetically operated switch. When current is passed through the coil of the relay, it magnetizes, producing an electromagnetic field that pulls the armature of the relay towards itself. This in turn opens or closes the contacts of the relay, which switches power on or off. This whole process is controlled by the relay\'s input control terminals.

The JS1AF-B-12V is designed to be shock and vibration resistant and is UL recognized, CSA approved, and rated for operation in temperatures from -40°C to +85°C. The unit can be used in the protection of electrical and electronic circuits, as well as in the control of motors and other motor-related applications. It is also suitable for use in electrically hazardous environments.

The JS1AF-B-12V power relay is a reliable and cost-effective solution for a wide range of high power applications. It is easy to install and provides a reliable current switching solution, ensuring that the connected circuits remain safe from damage. The robust design and UL recognition make it suitable for use in a variety of different environments.
