Power Relays, Over 2 Amps

PT5S7LC4 is a model number of a power relay used to control current above two amps. This compact relay offers a wide range of applications such as providing power to car-fuel pumps, lighting systems, and other small household applications. It is also used in high voltage applications as it is capable of handling up to 8,000 volts.

Application Fields

PT5S7LC4 is most commonly used in car-fuel pumps. As the cars become more complicated, manufacturers are adding more and more control components to the fuel pump. This relay can be used to both turn the fuel pump on and off automatically, as well as to adjust the fuel pressure and volume delivered to the engine.PT5S7LC4 is also used in lighting systems. This high-voltage, high-current relay is used to turn the lights on and off without damaging the wiring or circuitry. It is also used to control the brightness of the lighting system, as it can switch between different wattages.Other applications of this relay include household appliances, HVAC systems, and other small industrial equipment. It can be used to control the current to any device that needs to be switched on and off with precision.

Working Principle

The PT5S7LC4 operates by switching the current on and off using an electromagnet. When the electromagnet is energized, it causes the canted pole to move, along with the contacts, thereby opening or closing the circuit. This action is repeated many times per second, allowing the relay to operate at high speeds with a high degree of accuracy.The electromagnet energizes when a voltage is applied to the relay’s terminals. This voltage can either be from an AC power source, such as a wall socket, or from a DC power source, such as a battery. The current to the relay can be adjusted by changing the voltage level, allowing for precise control of the current and voltage being sent to the device.

Conclusion

PT5S7LC4 is a powerful high-voltage relay that is used in a number of applications, most notably in fuel pumps and lighting systems. It operates by using an electromagnet to switch the current on and off with a high degree of accuracy, allowing precise control of the voltage and current levels sent to the device. This makes it an invaluable tool for a wide range of applications.
