JS1-B-48V

JS1-B-48V is a power relay with stable operations over an amperage of more than 2 to maximum 4 Amps. This type of device was created to act as an intermediate switch for connecting two electrical circuits. It is a general-purpose use device, with its main application in controlling operations of electronic components or motors. In addition to its compact size and light weight, the JS1-B-48V boasts several features that make it a suitable choice for applications with its characteristics.

Technical features

The JS1-B-48V power relay includes a lead free Sn/Ag/Cu matrix and contact points along with low electromechanical noise, quick switching, good resistance to mechanical and electrostatic shock and a wide range of applications including HVAC systems and consumer electronics. Additionally, it features a 0.6 mm contact gap for better contact maintenance, 3 A resistive rated contact and roll off resistance that exceeds 200 Ohms. The coil is operated on a +/- 10% of rated voltage with a fluorescent yellow pickup indicator that is clearly visible on the face of the relay. The output power of the relay is indicated by the number of contact points it has, with the maximum being 4.

Application fields

The JS1-B-48V is primarily used in applications where a compact size and quick switching are required, either for automated or manual control of electrical circuits. This includes HVAC systems, consumer electronics, telecommunication, automotive, industrial control and LED lighting. It is usually used in applications with 200-240V AC power sources, providing a high-level of electrical isolation between the input and output circuits, a further increase in safety.

Working principle

The JS1-B-48V power relay is a device that uses electromagnetic force to mechanically operate a pair of contacts. It is composed of a coil and armature. When an electrical voltage is applied to the coil it creates an electromagnetic field, which then magnetically attracts the armature, causing it to move and close the contacts open. The armature is released from the contact point when there is no current going through the coil. Depending on the type of relay, the contacts can make or break the circuit, switching it on or off and allowing electricity to flow.

Conclusion

The JS1-B-48V power relay is a reliable, power efficient and cost-effective device for controlling electronic elements or motors for automotive or industrial applications. As it is very compact and light weight, it can be used in combination with other devices enabling multi-control. Its features and technical specifications make it suitable for electronic circuits with high current, thanks to the 3 Amps resistive rated contact and roll off resistance exceeding 200 Ohms. Moreover, the 0.6 mm contact gap provides better contact maintenance and the coil is operated at +/-10% of rated voltage.
