Power Relays, Over 2 Amps

The JS1A-48V-F are power relays with a switching power of over 2 amps. They are housed in a highly reliable plastic case with an extremely compact size and are designed to be contact-free and to provide long-term reliable operation in demanding environments.

Application Fields:

The JS1A-48V-F series can be used in a wide variety of applications, including lighting systems, motor controls, switching power supplies, and motor speed control. They can also be used as switches in industrial control applications, including power/surface switching, solenoid valves, heating elements, and heaters.

Working Principle:

The JS1A-48V-F utilizes a contact-free and zero-power design. An air gap between the switch contacts ensures that the cost of switching is reduced and the extended lifetime of these power relays is significantly increased. Additionally, by using a unique coiled spring as the switching member, the relays support very low contact resistance and high contact reliability over a wide temperature range. This allows for continuous operation in applications with extreme temperature fluctuations.

The working principle of the JS1A-48V-F is based on a “no changeover” technique. This feature ensures that the power relays are able to remain in either the “on” or “off” position without any readjustment. They can be set to switch either AC or DC current, at up to 48 V.

Endurance Capacity:

The JS1A-48V-F relays possess excellent endurance capacity in comparison to similar models in the market. Their unique sealed design enables them to operate continuously for up to 10 million times on a single coil. This is further increased to 20 million cycles on a higher power coil. Additionally, their high switching frequency is up to 300 operations/minute, making them ideal for frequent switching applications.

The JS1A-48V-F power relays also offer a wide range of mounting options. They are available with a variety of terminal styles, such as solder?tab terminals or PC-mountable terminals. For further convenience, the relays can also be replaced quickly with a pluggable terminal.

Benefits:

The JS1A-48V-F are an excellent choice for high power switching applications due to their low resistance, excellent endurance capacity, and versatile mounting options. As their contact-free design ensures a low arc, these relays are well suited for continuous operation in harsh environments. Additionally, their long-term reliable operation and low cost of switching make them a cost-effective choice.
