Cummins AVR Automatic Voltage Regulator generator system

Cummins AVR (Automatic Voltage Regulator) series is a key component in its generator system, which is used to automatically maintain the voltage at the generator output terminal at a preset value, ensure voltage stability, and protect the connected electrical equipment. The following is a related introduction:

Functional features

Voltage regulation: AVR detects the voltage at the generator terminal and compares it with the preset stable reference value. If there is a difference, it adjusts the excitation current to keep the generator output voltage within the specified range, and can compensate for the impact of the generator load, speed, temperature and power factor changes on the voltage.

Good stability performance: It can effectively reduce voltage fluctuations, provide stable power supply for various electrical equipment, and reduce the risk of equipment failure or damage due to unstable voltage.

Adapt to different working conditions: It can maintain good voltage regulation performance under the conditions of generator load changes, operating temperature changes and different power factors, ensuring that the generator can reliably supply power under various working conditions.

Cummins AVR has many models, the following are some common models:

MX321: It is standard configuration of STAMFORD ®S6 and HC6 series AC generators, and can also be provided as an option for the entire STAMFORD generator. This is an analog three-phase induction automatic voltage regulator, powered by a permanent magnet generator (PMG), which can isolate the impact of non-linear loads, enhance motor starting performance, and maintain short-circuit current.

MX341: High-quality STAMFORD generator voltage regulator board, suitable for Cummins generator sets, with good voltage regulation performance.

SX440: An AVR board in the global supply of diesel generator accessories, suitable for Cummins diesel generator sets, which can realize automatic voltage regulation function.

SX460: It has good dynamic response characteristics and can respond quickly to load changes to ensure voltage stability. It is often used in places with high requirements for voltage stability, such as data centers, hospitals and other important power supply places.

AS440: STAMFORD original voltage regulator board, belongs to AVR module automatic voltage regulator, suitable for Cummins related generator equipment.

ADVR-07AF: One of the commonly used AVR voltage regulator models for Cummins diesel generator sets. It has stable performance and precise regulation. It is widely used in various industrial occasions. It can automatically adjust the output voltage of the generator set to ensure that it is stable within the set range.

In addition, there are some other models of AVR voltage regulators, such as R449 and R450 of Leroy-Somer generators, DVR2000E and BE350 of Marathon generators, which can also be used in Cummins generator systems. The specific model to be used should be determined according to the series, power and actual application requirements of the generator set.

Application scenarios

The Cummins AVR series is widely used in various types of Cummins generators, covering multiple fields such as industry, commerce, ships, and electricity.

Industrial field: Provide stable power for factory production equipment, motors, automated production lines, etc., to ensure the normal progress of industrial production and avoid equipment shutdown or damage due to voltage fluctuations.

Commercial field: such as shopping malls, hotels, office buildings and other places, to power lighting systems, air conditioning systems, elevators and other electrical equipment to ensure a comfortable environment and normal operation of commercial places.

Marine field: used in the power system of ships, to provide stable voltage for various equipment on board such as navigation systems, communication equipment, living facilities, etc., to meet the power needs of ships under different working conditions.

Power field: In power systems such as power stations and substations, the AVR series helps to maintain the stability of power output, improve power quality, and ensure the reliable operation of the power grid.
