Description
The ABB 3BHE035301R0001 UNS0121 A-Z,V1 is a digital automatic voltage regulator and excitation controller from ABB's UNITROL 1010 product line. It is a compact, high-performance module for small and medium-sized synchronous generators and industrial machines requiring precise excitation control.
The unit accepts a wide input voltage range of 24–250 V AC/DC, making it adaptable to various power system configurations including single-phase 220 V and three-phase 380 V supplies. The generator voltage input covers 100–690 V AC at 50/60 Hz. Output field voltage ranges from 10 to 250 V DC, with continuous current output of 8–10 A DC and peak capability up to 16–20 A DC.
The UNITROL 1010 employs advanced microprocessor technology combined with IGBT semiconductor devices. Control algorithms include an adjustable PID controller for automatic voltage regulation, PID-based power factor and reactive power controllers, and a PI excitation current regulator. Voltage regulation accuracy is ±0.25% of the setpoint, with a response time of less than 20 ms for 95% step load changes.

Features:
- High-Precision Automatic Voltage Regulation (AVR)
- Fast Dynamic Response Control
- Multi-Mode Operation Capability
- Integrated Generator Protection Functions
The module operates using a DSP-based control system that continuously measures generator output voltage and compares it with reference values. Based on real-time feedback, the system adjusts excitation output to maintain stable voltage levels under varying load conditions.
The regulator supports multiple operating modes including automatic voltage regulation, power factor control, and reactive power control, allowing flexible integration into different power generation and industrial energy systems.
The 3BHE035301R0001 UNS0121 A-Z V1 ABB Voltage Regulator may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The controller supports multiple operating modes: automatic voltage control, power factor control, reactive power control, and manual control. For parallel generator operation, it provides reactive power distribution between islanded or grid-connected units, with automatic synchronization achieving phase matching within ±0.5° to ±2° and frequency matching within ±0.1 Hz.
Built-in dual channel support enables redundant operation with standby and setpoint tracking via a reliable CAN bus. System monitoring includes voltage transformer monitoring, synchronization check, and rotating diode monitoring (RDM). Protection features encompass over-excitation limiter (OEL), under-frequency protection (UFP), loss-of-field detection, overcurrent, overvoltage, and undervoltage protection.
- Metals & Mining: Controlling main drives in steel rolling mills, wire drawing machines, and mine hoists
- Cement & Minerals: Powering high-inertia cement kilns and heavy-duty material conveyors
- Pulp & Paper: Managing speed and tension alignment across multi-station paper production lines
- Power Factor Correction: Adjusts motor field current to optimize power quality across local industrial grids
- Large Pumps & Compressors: Provides stable starting and running torque for high-capacity pumps in water treatment and oil/gas pipeline stations
This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Grounding (PE): Ground the device via Terminal 17 with a minimum 4 mm² grounding cable to the protective earth to prevent EMI.Power & Excitation (Top/Bottom Terminals): Connect the auxiliary power and excitation outputs as defined in the system's wiring diagram.
I/O Separation: Route control and I/O wiring separately from power and excitation cables to prevent electromagnetic interference (EMC).
Communication Ports: Use the dedicated USB cable for local parameter configuration via your PC, or connect via the Ethernet port.
Technical notes
The dual processor architecture ensures regulation control is maintained even during Ethernet communication interference. The unit operates over −25 °C to +55 °C (extended claims to −40 °C to +70 °C) with 5–95% non-condensing humidity and vibration resistance up to 2 g. It carries DNV marine certification, UL 508, and CE marking.
