Power relays offer a fast, efficient, and affordable way to control power to a number of different applications. The MJN3CF-DC110 power relay, manufactured by Panasonic, is a powerful and reliable solution for applications needing to switch more than two amps. In this article, we will explore the MJN3CF-DC110’s application field and working principle.

MJN3CF-DC110 Application Field

The MJN3CF-DC110 is a medium to large power relay ideal for use in a wide range of commercial, industrial, and residential applications. It is rated up to 3A at 250VAC or 6A at 48VDC, making it a powerful and reliable solution for applications needing to control high current loads.Typical applications for the MJN3CF-DC110 include air conditioning, heating, refrigeration, lighting systems, and other control systems where multi-amp relay control is required. The MJN3CF-DC110 is also compatible with the Omron G9SE series of solid-state relays and switches, allowing for greater flexibility and customization for controlling various systems.

MJN3CF-DC110 Working Principle

The MJN3CF-DC110 is a standard 12V DC powered relay, with a working current of 18mA and a maximum switch capacity of 6A/48V DC. As with all power relays, the MJN3CF-DC110 works by using an electromagnet to physically move contacts inside the relay, thus switching power on and off. When voltage is applied to the coil, the core of the electromagnet is magnetized, which causes the movable contact to be attracted to the stationary contact. When the movable contact touches the stationary contact, power is conducted from the input side to the output side of the relay. When voltage is removed from the coil, the core of the electromagnet is no longer magnetized, thus releasing the movable contact from the stationary contact and switching the power off.The MJN3CF-DC110 is also equipped with a time-delay feature, which allows for a pre-set delay between when the voltage is applied and when the relay switches. This feature can be used to control peak inrush current for better system performance as well as reduce stress on the contacts.

Conclusion

The Panasonic MJN3CF-DC110 is a reliable and cost-effective power relay capable of switching high current loads up to 6A/48V DC. Its rated current of 3A at 250VAC and time-delay feature make it a great choice for many industrial and residential applications requiring continuous or intermittent switching. Its compatibility with the Omron G9SE series of switches and relays also adds an extra level of versatility, allowing for greater customization of control systems.
