Power Relays, Over 2 Amps: KRPA-5AG-120 Application Field and Working Principle

Introduction

KRPA-5AG-120 is a new type of power relay developed by YGON Automation in 2018. It is part of YGON\'s new series of industrial relays, which meet the electrical requirements of most applications. This type of power relay is designed to operate at up to 120 amps of power, making it ideal for applications that require more power and current than most other relays can provide. It is a fairly robust device, with a contact rating of 10A/30Vdc, a coil voltage rating of 12-240Vac/dc, a power rating of up to 120A, and a contact resistance of 20m. It is also UL recognized and CSA certified.

Application Field

The KRPA-5AG-120 power relay is ideal for a wide range of applications such as industrial motor control, HVAC systems, lighting control, and automotive applications. It is also well suited for applications that require high power and current such as electric vehicles, solar energy systems, and electric motors in home appliances. It is especially useful in applications that require reliable, safe, and efficient power and current control, such as those used in medical equipment.

Working Principle

The KRPA-5AG-120 power relay works on the principle of electromagnetic induction. It uses an internal coil to generate an electromotive force whenever a voltage is applied to it. This EMF opens up the normally closed contacts, allowing current to flow and activates connected devices or circuits. When the voltage is removed, the EMF disappears, which causes the contacts to close and the connected devices or circuits to deactivate. This cycle can be repeated as many times as necessary to control power and current.

Conclusion

The KRPA-5AG-120 is an excellent choice for applications that require more power and current than other relays can provide. Its robust design, high power rating, and UL and CSA certification make it ideal for applications in medical equipment, electric vehicles, solar energy systems, HVAC systems, and more. By understanding its application field and working principle, users of this power relay will be able to take full advantage of its capabilities and ensure their applications run smoothly.
