JS1APF-B-18V-F

Power Relays, Over 2 Amps

The JS1APF-B-18V-F is a versatile, general-purpose power relay, designed for applications that require switching of larger current and voltage loads with greater reliability and power-handling capability. It is commonly used for switching devices such as electric motor starters, contactors, solenoids, lamps, pilot lights, capacitor banks, and other types of loads, including those with high inrush currents.

Application field

The JS1APF-B-18V-F is suitable for use in a variety of applications, including:

• Industrial machines and robotic systems that require a larger current and voltage load.
• Building control systems that require switching of high voltage and current loads.
• Automotive, refrigeration, and other systems that involve switching of current and voltage loads.
• Lighting control systems that require switching of higher current and voltage loads.
• Electrical systems that involve switching on and off greater amounts of electrical energy.

Working Principle

The JS1APF-B-18V-F is a single-pole, double-throw (SPDT) relay. It consists of three main components: an electromagnetic coil, a contact armature, and a switching mechanism or bridge. When the current in the coil exceeds the holding current, the armature is drawn to the magnet, because of magnetic attraction. As the armature moves, the contact arms open and close, and the switching mechanism or bridge activates a set of contacts, opening or closing the circuit.

The JS1APF-B-18V-F’s two independent sets of contact arms can be switched in parallel or independently, allowing for the connection of higher current and voltage loads. The power relay is typically used to switch loads when current is higher than that which can be handled by a switch. The power handling capabilities of the JS1APF-B-18V-F make it a good choice for a variety of applications.

In addition, the JS1APF-B-18V-F features a robust design, which includes a sealed electromagnetic coil and a non-metallic outer shell. This design ensures that the power relay can withstand extreme temperature fluctuations, humidity, and other environmental factors. This makes the JS1APF-B-18V-F a reliable and efficient power switching device that is suitable for use in a wide range of applications.
