Power Relays, Over 2 Amps: KRPA-5DG-12 Application Field and Working Principle

The KRPA-5DG-12 Power Relay is used to provide over two amps of electricity for certain applications. With its high current capacity and low insertion and hold loss, the KRPA-5DG-12 relay is well suited for the job. The relay has a wide operating voltage range of 12-350 volts AC and an 80-100 mA contact rating. The KRPA-5DG-12 relay has three main application fields.

Lighting Control

The KRPA-5DG-12 Power Relay can be used to control lighting in industrial and commercial settings. The high current capacity means that it can be used to control lighting in large areas such as warehouses and auditoriums, while the low insertion and hold loss provides reliable and efficient operation. Additionally, the wide operating voltage range ensures compatibility with most current light fixtures.

Safety & Security

The KRPA-5DG-12 relay is also used for safety and security applications. The relay can provide a high current capacity for the main circuit powering the security system, as well as for low current control mechanisms such as door and window sensors. The wide operating voltage range also allows the use of additional devices such as CCTV cameras, PIR sensors, and sirens.

Motor Control

The KRPA-5DG-12 relay can be used to control various types of motors. The relay has an 80-100 mA contact rating, which is sufficient for most motor applications. The relay\'s low insertion and hold losses make it ideal for motor control applications, as it can provide efficient and reliable operation. Additionally, the wide operating voltage range ensures compatibility with most motor types.

Working Principle

The KRPA-5DG-12 relay works by switching an armature, which is positioned between two contacts. When the armature is in an open position, no current flows. When the armature is activated, either through an electrical signal or mechanical switch, it will close the contacts and current will flow. The armature can be held in the open or closed position for a predetermined amount of time, depending on the relay\'s configuration.

The KRPA-5DG-12 Power Relay is a versatile and reliable component for over two amps of power control applications, which can be divided into three main fields of application. The relay has a high current capacity and low insertion and hold loss, making it ideal for controlling lighting, safety and security, and motor applications. Additionally, the relay has a wide operating voltage range, allowing it to be used with a variety of devices.
