Power relays are electric components used to power electrical loads. They are designed for applications that require more than two amps, such as controlling motors, lights, and other equipment. The ALE12B48 is a type of power relay that provides various features for many diverse applications.

The ALE12B48 is a compact, low-cost power relay with a wide operating temperature range and high voltage breaking capacity. It is a single-pole double throw (SPDT) relay with mechanically actuated, silver-cadmium oxide contacts. The ALE12B48 can be used in various applications requiring more than two amps, such as motor control, switching lights or other electrical equipment, or providing a separate on/off switch for devices.

The ALE12B48 relay has a contact rating of 12A, with a voltage rating of 120 V AC/DC maximum and a power rating of 1440 VA. The operating temperature range is -30°C to +85°C. In order to protect the contacts from arcing, the relay is equipped with a fixed contact gap. The silver-cadmium oxide contacts are highly resistant to corrosion and oxidation.

The coil of the ALE12B48 is designed with an insulation class of B (105°C) and the contacts are rated for a maximum of 80,000 electrical operations. The relay is also equipped with a response time of approximately 15ms, making it suitable for high-speed applications. The mechanical life is rated for 1 million operations, giving the relay a long service life in busy environments.

The ALE12B48 power relay is suitable for a variety of applications, including motor control, switching lights and other electrical equipment, alarm systems and computers. It is also used in industrial and commercial settings, such as factories, manufacturing plants, and transportation systems. The relay is commonly used in applications where multiple settings of several controlled parameters are required.

The working principle of the ALE12B48 is relatively simple. When the relay is energized, the coil creates a magnetic field and pulls the armature inside its housing. This causes the contacts to close and allows current to flow through the circuit. The contacts remain closed until the current is stopped or the coil is de-energized, in which case the contacts open and the circuit is no longer connected.

The ALE12B48 is a reliable, cost-effective power relay suitable for applications requiring more than two amps. It has a long service life and the silver-cadmium oxide contacts offer excellent resistance to corrosion and oxidation. The wide operating temperature range and high voltage breaking capacity make it suitable for a variety of industrial and commercial applications.
