The ABB Unitrol 1020 is a powerful and compact automatic voltage regulator (AVR) designed for small and medium synchronous generators and industrial machines. It is part of the ABB UNITROL 1000 family, which also includes the UNITROL 1010.

The Unitrol 1020 offers a variety of features, including:

• Automatic voltage control with adjustable PID controller: This ensures that the generator’s output voltage remains stable, even under changing load conditions.
• Power factor and reactive power controller with PID control algorithm: This allows the Unitrol 1020 to optimize the generator’s power factor and reactive power output.
• Dual channel support: This allows the Unitrol 1020 to be used with two generators in parallel.
• Advanced load sharing between machines operating in parallel: This ensures that the load is evenly distributed between the generators.
• Rotating diode monitoring: This protects the generator’s exciter from damage.
• Automatic synchronizing: This simplifies the process of bringing a generator online in parallel with another generator.
• Several integrated communication options: This allows the Unitrol 1020 to be easily integrated into a plant’s control system.

The Unitrol 1020 is a versatile and reliable AVR that is suitable for a wide range of applications. It is a good choice for industrial plants, power plants, and other facilities that require a stable and reliable source of power.
