Power relays are essential components in today\'s electrical circuits, and the KR-3DH-12 is a popular type that features over 2 amps capacity. It operates by leveraging the magnetic force created when an electric current is passed through a coil. This ensures reliable switching performance, with an ultra-low power consumption.
The KR-3DH-12 relay features a standard-size PCB for easy installation. It also has a high dielectric strength, of 2000VAC for one minute, meaning it can resist strong surges of electricity that may otherwise damage other components.
In addition to this, the KR-3DH-12 is IP66 rated, meaning it is resistant to dust and water, making it an ideal choice for outdoor applications. Its operating temperature range is between -40 and +85°C and it has excellent heat resistance.
In terms of its construction, the KR-3DH-12 uses electroplated zinc alloy steel with silver nickel contacts, along with tin plated copper terminals. The use of these materials ensures excellent electrical and heat performance.
As for the working principle, the KR-3DH-12 relay uses an electromagnetic coil, coupled with one or more contacts, to control an electrical system. When the coil is powered, a magnetic force is generated which engages the contact to switch on. This process is then reversed when the power is removed, and the contact reverts to its original state.
What is more, the KR-3DH-12 can be configured for either normally open or normally closed operations. This makes it a versatile device as it can be used for a variety of applications, such as mains power switching, security system activation, or motor control.
In conclusion, the KR-3DH-12 is a versatile power relay with excellent dielectric strength and a wide operating temperature range. It is also IP66 rated, making it an ideal choice for outdoor applications. With its high performance and superior electrical and heat properties, the KR-3DH-12 is a popular choice for a variety of applications.
