Marathon SE350 Voltage Regulator AVR

Purchasing a new generator is a smart decision to ensure that you have a constant and stable supply of power in your home and business. However, in order to ensure that your sensitive electronic equipment such as televisions, microwaves, and computers are safe, you need an original Marathon SE350 AVR. The Marathon Automatic Voltage Regulator will offer you a means of ensuring that your critical equipment operates within the voltage ranges as recommended by manufacturers. 

What is the Automatic Voltage Regulator?

The Marathon SE350 voltage regulator is a critical generator component in ensuring that your generator output voltage is reliable and of quality. The AVR is a small, but economical, part that is the brainpower behind controlling and regulating the production of voltage by your generator at home or work. 

In the majority of applications, the loads always fluctuate and are sometimes unpredictable; your AVR is the component charged with the responsibility of ensuring that your Marathon alternator is responsive. This means that the alternator is better capable of quickly responding and adapting to load impacts during all operational stages. 

How does the Marathon SE350 voltage regulator AVR function?

Inside the Marathon generator alternator is a small magnetic field created by the generator’s motion. The magnetic field creates residual voltage on the generator’s windings. The AVR then steps in and derives excitation from the residual voltage, creating more voltage on the generator’s exciter till the required voltage level is achieved.

The AVR continuously monitors the output voltage ensuring that the input voltage to the generator’s exciter is controlled. Through reducing or increasing the generator control voltage, your generator output voltage is increased or decreased proportionally. During its operation, the AVR runs calculations on the output voltage required by the exciter every few seconds. This helps to create a steady output voltage based on set points to compensate for the generator’s power factor, temperature, engine speed, and load

Features of the Marathon SE350 AVR

The Marathon SE350 not only controls the output from AC generators, but also comes with the following features that make it a must-have for your home or business generator application:

• A 4 A, 250 V fuse found in the rear face of the AVR
• A screwdriver adjustable potentiometer for adjusting your generator’s output voltage
• Capability of adding a remote voltage adjust rheostat by just removing a jumper wire
• A screwdriver adjustable potentiometer for system stability

Advantages of purchasing the SE350 AVR

The Marathon SE350 Voltage Regulator AVR, P/N 761594-01 is a 100% certified original product exclusively manufactured and engineered by Marathon Electric from the United States. From 1913, Marathon Electric has been on the frontline of offering quality electric products for various business and residential applications. Purchasing the SE350 automatic voltage regulator, offers you access to advantages such as: 

Choosing genuine parts for your generator is the wisest decision you can make. Your generator is only as strong as its weakest component and this can make an enormous difference between increased productivity and failure of your critical power systems.

eneral Description / Specifications

 

The R448 positive voltage build up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of the AVR. The AVR is linked with the main stator windings and the exciter field windings to provide closed loop control of the output voltage with load regulation of +/- 1.0%.

In addition to being powered from the main stator, the AVR also derives a sample voltage from the output windings for voltage control purposes. In response to this sample voltage, the AVR controls the power fed to the exciter field, and hence the main field, to maintain the machine output voltage within the specified limits, compensating for load, speed, temperature and power
factor of the generator.

Thyristor voltage regulator
A thyristor voltage regulator was fitted so as to upgrade the ± 5% voltage tolerance previously achieved to ± 0.5%. The regulator in question is a pure voltage regulator, which uses the excitation current to keep the generator voltage constant irrespective of the load.

The generator voltage is fed via the measuring circuit transformer to the regulator and rectified by a load-side rectifier bridge. The actual value signal and regulator input voltage are derived from this DC voltage. The voltage setpoint is input via an internal reference value potentiometer or external reference value setter. After an internal setpoint/ actual value comparison, the regulator amplifier outputs a DC voltage, which is converted by a loadside pulse generator into a firing pulse with adjustable time offset for the bypass thyristor.

The bypass thyristor Vabs is situated in the excitation circuit between one phase and the anode-side output of the rectifier bridge in series with the bypass resistor Rabs (Fig. 4). The bypass circuit, parallel to excitation winding RE, is switched on in the time ranges at which valve V5 is conductive. Part of the excitation current can therefore be made to bypass the excitation winding. This takes place within every period for a fraction of that period (control angle). The excitation current is reduced in accordance with the control angle and the resistance ratio Rabs/ RE.
