Power relays are devices capable of switching high voltage or high current circuits with a low voltage, low current input signal. The MM4XKP-JD DC100/110 is a DC power relay suitable for handling currents above two amps. In this article, we will discuss its application field and working principle.

Application Field

DC100/110 power relays are ideal for use in vehicle-mounted equipment, factory automation equipment, and machine tools. Some of their key benefits include:

• High current rating of 2.5 amps and 10 amps inrush current rating
• High switching capacity with a single pole up to 8kw
• Wide operating temperature range from -40 to 85°C

The DC100/110 also has short form A and changeover contact poles, with high switching frequency and excellent environmental properties, making it an ideal solution for many industrial, commercial and consumer applications.

Working Principle

The MM4XKP-JD DC100/110 is enabled by a low voltage signal to drive a permanent magnet AC (PMAC) electromagnet. This produces a magnetic force which closes the electrical contacts in the power relay. This power relay then locks against the force of the magnetic field unless an external force is applied to the handle to reverse the current, creating a latched, zero power position and de-energizing the load.

The low voltage input signal is usually connected to the transistor base which passes the current through the magnet. The DC power relay is also equipped with a built-in device for abnormal current detection, providing protection against overloads and short circuits. This further enhances the safety of the device and ensures smooth, reliable operation.

The MM4XKP-JD DC100/110 is an extremely reliable and versatile DC power relay capable of switching high loads in a variety of industrial and consumer applications. Its easy installation, built-in safety features, and wide operating temperature range make it a perfect choice for many applications.
