The self-contained power package provides a variety of features including overload protection, adjustable start times, and networkable diagnostic capabilities. It is capable of supplying voltage from 5kV to 36kV and current up to 800A. This article will explore the application fields and working principle of UMQ-3727-A.

Applications

The UMQ-3727-A can be used in multiple industrial applications. It is commonly used in industrial, commercial, and marine sectors. In industrial applications, it is often selected for low and medium voltage switchgear, such as circuit breakers, contactors, switches, as well as transformers. It is also used as an overload protection device for motors. In the commercial sector, it is used for switchgear solutions, such as power distribution, distribution boards, and flexible alternative power solutions such as wind and solar. In marine applications, it is used for shipboard power and propulsion systems.

The product can be used in many power applications, including air cushion platforms, air intakes, air conditioning, industrial heating, and industrial refrigeration. It is also used in wastewater treatment and processing applications. In addition, it can be used as a cycle timer, start/stop motor, remote start/stop, speed control, overload protection, and fault diagnosis. It can also provide output voltage, current, voltage, frequency, and phase monitoring.

Working Principle

The UMQ-3727-A uses a high-speed current-sensing circuit, which senses the current in the medium voltage circuit. When the current level reaches the maximum safety limit, the onboard protection system will trigger the circuit breaker to switch off the circuit and ensure safe operation. The self-contained power package also provides protection against short circuit failure and overvoltage protection. Additionally, the internal control systems are able to provide diagnostic information to a control station.

The product is designed for easy setup and operation. It has multiple connection interfaces including last-mile communication fibre links, carrying both power and signal information. It is capable of supplying current of up to 800A, and is able to switch maximum 24kV AC voltage. It has adjustable start up time and initial current settings.
