Construído para combinar Gerador Universal - Regulador Automático de Tens?o AVR EA63-7D

Introducing the Automatic Voltage Regulator AVR EA63-7D, the perfect solution for maintaining the voltage stability of your universal generator. With its advanced features and reliable performance, this AVR is designed to ensure optimal voltage regulation and protect your valuable equipment.

The EA63-7D is specifically crafted for use with universal generators, making it compatible with a wide range of applications. Whether you need to power your home, office, or industrial machinery, this AVR is up to the task.

Equipped with a sensing input of 220/440 VAC ± 10% and 1 phase, this AVR is capable of handling diverse voltage requirements. Combined with a frequency of 50/60 Hz that is selectable, this regulator guarantees seamless operation in any electrical system.

With a power input voltage range of 180~260 VAC ± 10% and 1 phase 2 wire, the EA63-7D ensures a stable power supply to your generator. It is designed for frequencies of 50/60 Hz, accommodating different power grids and allowing for versatile usage.

In terms of output, the AVR offers a maximum voltage of 63 VDC, making it ideal for a wide range of appliances and equipment. Additionally, it delivers a continuous current of 7A, with the ability to handle intermittent loads of 15A for up to 10 seconds. This robust performance ensures that your generator operates smoothly even during periods of high demand.

The voltage regulation capabilities of the EA63-7D are exceptional. With a voltage build-up that maintains a residual voltage at the AVR terminal of over 5 VAC, this AVR guarantees consistent power supply. Furthermore, it offers a voltage adjustable range of 180~277 VAC @220V and 360~554 VAC @440V, allowing for precise voltage control to meet the specific requirements of your application.

To further enhance its performance, this AVR features a thermal drift of only 0.05% per °C change in AVR ambient temperature. This ensures that the voltage regulation remains accurate even in varying environmental conditions. Additionally, it offers external volts adjustment, allowing for fine-tuning of the voltage output using a 1K ohm 1-watt trimmer.

The EA63-7D is equipped with EMI suppression and internal electromagnetic interference filtering. This technology minimizes electrical noise and prevents interference from affecting the performance of your generator. With a maximum power dissipation of 20 watts, this AVR operates efficiently and effectively.

For added safety, the AVR is designed with under-frequency protection, presetting the knee point at 55 Hz for 60 Hz systems and 45 Hz for 50 Hz systems. This feature ensures that your generator shuts down in case of frequency deviations, preventing potential damage to the equipment.

Furthermore, the over excitation shutdown feature safeguards your generator against excessive exciter field voltage. If the field voltages exceed 65 ± 2 VDC, this AVR will shut down after a time delay, protecting your system from overexcitation.

With quadrature droop sensitivity of 4% @ 2A and a maximum input of 5A, the EA63-7D ensures excellent load sharing and stability. This enables your generator to efficiently distribute power to multiple appliances without compromising performance.

In conclusion, the Automatic Voltage Regulator AVR EA63-7D is a reliable and efficient solution for maintaining voltage stability in your universal generator. Its advanced features, precise voltage regulation, and exceptional performance make it an essential component for any electrical system. Invest in the EA63-7D and experience uninterrupted and reliable power supply for your applications.
