Stamford’s MX341 Voltage Regulator AVR provides safe, steady and controlled generator output voltage
SAME EXACT AVR AS:

- Olympian Voltage Regulator 594-003 AVR
The Stamford MX341 Voltage Regulator AVR provides a steady, safe and controlled buildup of generator output voltage, making this voltage regulator a multifaceted yet stable model, which can be paired with similar products.
The MX341 features a two-phase Automatic Voltage regulator, which makes up a part of the excitations system for the brushless generator.
The MX341 features a three-phase permanent magnet generator (PMG). This helps to ensure low Radio Frequency Interference and helps protect against thyristor type loads.
Additionally, this ensures preset output voltage specifications are maintained by feeding power to the exciter stator and main rotor in a controlled way. It does so by compensating for the temperature, load, power and speed of the generator.
The AVR circuitry has a number of protective features to ensure control over the generator, and the inclusion of soft start circuitry provides a smooth buildup of output voltage. The MX341 monitors the shaft speed of the generator and ensures the excitation system is provided with under-speed protection.
Additionally, the MX341 features turbocharged engines with improved frequency recovery time thanks to an adjustable volts/Hz slope.
Stamford’s MX341 provides a number of features that grant the user more control over the generator, and that guarantee safety in the process.
The AVR output device has an internal shutdown ability, to prevent uncontrolled over-excitation, and until the the generator is shut down this remains latched. The user has greater control of the generator’s output, thanks to a provision that allows a remote voltage trimmer to be connected. The soft start circuit provides a linear rising voltage, and the stability circuit provides adjustable ac feedback to maintain steady performance of the control system.
The MX341 features an overload detector, which shuts down the output device if overloads last more than 10 seconds. The overload detector continuously monitors the excitation level and sends shutdown signals. If overload occurs, the generator will be stopped and will need to be reset.
