Overview
Essential details：UNITROL-1010 brushless excitation system
UNITROL 1010 is a powerful small indirect excitation system with built-in support for dual channels for advanced load distribution, rotating diode monitoring, automatic synchronization and multiple all-in-one communication options in parallel running units.
The UNITROL 1010 is a voltage regulator in the UNITROL 1000 series designed for use in small and medium-sized synchronous generators and industrial machines. IGBT semiconductor devices based on advanced microprocessor technology and allowing current outputs up to 10ADC for continuous operation.
The UNITROL 1010 performs high performance in harsh conditions and different temperature ranges and is fully compliant with DNV and UL standards. The additional features of UNITROL 1010 compared to the previous version are Ethernet,USB connectivity, data and event logging and many new features.
The UNITROL 1010 is a miniaturized device designed for devices with excitation currents up to 10A. Share the same interface and size as the UNITROL 1020.

UNITROL-1010 brushless excitation system
When the AVR operates,
• The voltage in the power section can be up to 300 V AC and the short-circuit current is very high.
• The voltage in the control cabinet is more than 50 V.
When the AVR is disconnected from power supplies, the large capacitors in the AVR hold a charge for some time. Wait for at least 5 minutes for the capacitors to discharge before you do work on the AVR. An amber warning LED flashes if the internal voltage is more than 30 V DC.
Warning labels are attached to all of the cubicle doors to warn personnel against opening the doors during operation.
If the device is built into a larger system, additional warning labels are attached to the inside of the cubicle doors and to the covers of the power converter modules.
Consider the residual danger areas when you do work on the excitation system:
• Danger from live equipment inside the excitation system, if the protective covers are removed.
• Hazardous voltages from the rotor field winding and the secondary side of the excitation transformer.
• Danger from charged capacitors if a cabinet door is open immediately after the system stops.
• Danger from main and auxiliary voltages when cubicle doors are open.
