KU93-90050

Power Relays, Over 2 Amps

KU93-90050 is a type of power relay that is designed to manage power flow within a circuit. It is rated to handle over 2Amps of current, making it suitable for various applications; electrical motors, HVAC systems, pumps, fans, and other industrial or residential applications.

Physical Construction

KU93-90050 is constructed of heavy-duty plastic composite material. The base and body of the relay are riveted for added strength and durability, making it suitable for long-term use. The contacts are silver-plated copper alloy, ensuring they can handle the high current without vaporizing or burning out. The coil is magnetically shielded for added protection. The system is sealed with a polyurethane cover for extra protection.

Application

KU93-90050 is most commonly used in HVAC systems, electric motors, pumps, and fans. It can be used as an on/off switch in power circuits to maintain safe current flow. For example, the fan in a HVAC system can be powered with a KU93-90050 in order to regulate the air flow to maintain optimum temperature. The same relay can be used in an electric motor to manage start, stop, and speed regulation.

Working Principle

A power relay works by using an electromagnetic field to move an armature against a spring, allowing current to pass through contacts. KU93-90050 can be triggered or turned on/off using an external voltage source. Upon energizing, the electromagnetic field pulls the armature and opens the contact points, allowing the current to flow through. When the external voltage source is removed, the armature returns to its original position and the contact points close, stopping the flow of current.

KU93-90050 is a reliable and durable relay that can handle over 2Amps of current. Its design makes it suitable for various applications, such as HVAC and electrical motors. Its working principle is based on the movement of an armature against a spring, allowing current to pass through contact points.
