KUMP-11A18-24

Power Relays, Over 2 Amps

The KUMP-11A18-24 is a Power Relay with an Ampere rating of over 2 amperes. It is designed for applications such as lighting , motor control, and for high voltage power switching.

The KUMP-11A18-24 has a maximum voltage rating of 240 VAC and a nominal load rating of 4.0 A. Additionally, the KUMP-11A18-24 has a maximum relative humidity of 10%, a temperature range of 0 to 95°C, and a maximum operating frequency of 5 kHz.

The KUMP-11A18-24 is composed of an electrical contact, a coil, a base, and a signal diode. The electrical contact is a normally-closed contact that opens and closes depending on a signal from the coil. The coil is what activates the relay when an electrical current is applied to it. When the coil is energized, the contact opens.

The base of the relay is designed to provide stability to the component and to help dissipate heat generated by the relay. The base also allows for the mounting of the relay and keeps mechanical vibrations from affecting the contact.

The signal diode is an important part of the relay as it is used to prevent back-electromotive force from damaging the electrical contact when the coil becomes de-energized. The diode also reduces the amount of inductive kickback that can be produced by the contact when it changes from closed to open.

The working principle of the KUMP-11A18-24 is simple. When an electrical current is applied to the relay’s coil, it creates an electromagnetic field that causes the relay contact to open and close. When the coil is de-energized, the contact returns to the normally-closed position.

The KUMP-11A18-24 is a popular choice for applications such as motor control, lighting, and high voltage power switching. Its ratings and low-cost make it a suitable choice for applications that require only a few A of current. Additionally, its signal diode and robust mechanical construction make it a great choice for applications where reliability and durability are a priority.
