Power Relays, Over 2 Amps

JS1A-B-18V is categorized as a power relay with a rated current of over 2 amps. It is one of the most commonly used relays, due to its robust design and wide range of applications.

Application Field

Power relays, especially ones with over 2 amps, are often used in solar power systems, energy storage systems, motor drives, LED lighting applications, and power back-up systems. They are also suitable for use in high-power electrical equipment control. These relays are highly reliable and feature a low contact resistance, extremely fast operating times, and high current carrying capacity.

Working Principle

The JS1A-B-18V works by utilizing an electromagnetic system. This system works by having an armature coupled with two coils: control and operative. When the control coil is energized, the magnetic force causes the armature to move and connects the operative contacts. This enables the current to flow from one contact to the other, allowing the relay to remain energized. When the control coil is disconnected, the armature is released from the magnetic force and the contacts to separate, cutting off the current and de-energizing the relay.
