Reemplazo perfecto para Marathon - Regulador automático de tensión AVR DVR2000E

The DVR2000E is a high-quality Electric Voltage Regulator manufactured by MARATHON. Designed with advanced features and innovative technology, this AVR (Automatic Voltage Regulator) guarantees reliable and stable power output for a wide range of applications.

One of the key features of the DVR2000E is its True RMS Sensing capabilities. This regulator can be configured for one or three-phase operation and can sense voltages ranging from 95 to 600 volts with an accuracy of ±10% at 50/60 hertz. Unlike average sensing regulators, the patented circuitry of the DVR2000E senses true RMS voltage, ensuring superior load regulation and enhanced performance.

Another notable feature of the DVR2000E is its Soft-Start Ramp function. During initial start-up, the regulator provides a controlled increase to the rated voltage, limiting the overshoot of voltage during voltage build-up. This feature not only protects connected equipment from sudden voltage spikes but also extends the lifespan of the generator.

The DVR2000E also incorporates Engine Unloading capabilities. It constantly monitors the rate of frequency change during transient conditions and adjusts the voltage accordingly. This additional voltage dip during speed drop allows the engine to recover faster and ensures uninterrupted power supply even during sudden load changes.

To protect the generator from sustained overvoltage, the DVR2000E is equipped with an Overvoltage Shutdown feature. The overvoltage point is preset at 20% over normal generator operating voltage, and the regulator has a preset timeout of 0.75 seconds. This provides reliable generator protection and prevents damage due to excessive voltage.

For advanced control options, the DVR2000E offers a VAR/PF Controller (Model DVR 2000EC). When paralleled to utility power, this controller allows the user to select and change between VAR (Volt-Ampere Reactive) or PF (Power Factor) control through regulator adjustments. This flexibility in control settings ensures optimal power management and efficient operation.

Built to withstand harsh environments, the DVR2000E features an encapsulated design. This design provides maximum protection against moisture or abrasive contamination, significantly reducing the risk of early regulator failure. The regulator has been extensively tested to meet MIL-STD-705, Method 711.1C, and is salt fog tested to MIL-STD-810E standards.

The DVR2000E offers both Auto/Manual Mode operation. The exciter field current can be controlled by the regulator or manually set at a fixed value. This flexibility allows users to easily switch between automatic voltage regulation or manual control depending on their specific requirements.

In conclusion, the DVR2000E Electric Voltage Regulator from MARATHON is a technologically advanced and reliable solution for voltage regulation. With its True RMS Sensing, Soft-Start Ramp, Engine Unloading, Overvoltage Shutdown, and VAR/PF Control capabilities, this AVR ensures stable power output under varying load conditions. Its encapsulated design and rigorous testing make it suitable for use in challenging environments. Choose the DVR2000E for superior voltage regulation and enhanced generator protection.
