UB2-12NU-L Relays

UB2-12NU-L is one of the signal relays that support up to 2 Amps. It is commonly used to control a variety of applications ranging from 50% of adjustable current capacity to its near-zero current Setting range, designed to make the relay switching operation more reliable and efficient. This article provides an overview of the UB2-12NU-L application field and working principle.

One of the primary application fields of UB2-12NU-L is in telecommunication, in which the signal relays are used to control line current and loop current. The UB2-12NU-L provides adjustable current capacity for 50% of its rated current so that the warning or control level can be adjusted more precisely. Furthermore, the near-zero current Setting facility can effectively reduce chatter in communication lines and save energy.

Additionally, the UB2-12NU-L can also be used in motor control applications. The relay can be activated using a lower power level than that of the motor to be controlled, and its adjustable current capacity allows users to select any current level within the rated current range. This makes the relay ideal for controlling motors of various power, ensuring precise control and energy savings.

In terms of working principle, the UB2-12NU-L relay uses the standard Reed Switch technology. This technology relies on an electromagnet that creates a magnetic field which causes the two contacts in the switch to close. When the current applied to the magnetic field reaches a certain level, the contacts close and the current is interrupted. The UB2-12NU-L offers an adjustable current setting, which allows the user to select a desired on/off current level. This makes the device very suitable for applications where precise current control is required.

In conclusion, the UB2-12NU-L is a signal relay that is used for a variety of applications, ranging from telecommunication to motor control, where precise current control is essential. It uses the standard Reed Switch technology and also provides adjustable current capacity, allowing users to select any current level within the rated current range.
