JQ1P-B-12V

Power Relays, Over 2 Amps

JQ1P-B-12V relay is a common type of power relay with high current rating, which has a wide variety of application fields. It is usually rated for 10 A at 125 VAC and 24 VDC, as well as 5 A at 250 VAC. The contact material is silver alloy, and it can be used for switching on and off various electrical equipment.

Application Fields

FJ1P-B-12V relays are widely used in various industries ranging from machines to industrial equipment. It can be used for high-current switching control for heavy machinery, such as motor starters and airplane engines. It is also suitable for general-purpose applications such as automotive control systems, as well as electronics such as amplifiers and power supplies.

Working Principle

The JQ1P-B-12V relay works by using an electromagnet to open and close the contacts in the relay. When the current flows through the coil of the relay, it creates a magnetic field that attracts the armature inside the relay, thus actuating the contacts. Then the current can flow in either direction and the contacts are open and closed accordingly.

In order to protect the contacts from damage due to high current, a buffer capacitor is usually connected in series with the relay. This capacitor absorbs any spike of current and thus prevents the contacts from being burned out. The buffering capacitor also helps to reduce the humming noise made by the relay.

Conclusion

The JQ1P-B-12V is a high current rating relay with a wide variety of applications. It is used for switching control of heavy machinery, automotive control systems, and general purpose electricity needs. Its working principle has the electromagnet causing the armature to actuate the contacts, while a buffer capacitor is usually connected in series to protect the contacts from damage due to high current.
