UNITROL 1005-0011 3BHE043576R0011 ABB

Technical Parameters:

Excitation Output Current: Nominal continuous output current up to 5 A DC (with maximum transient ceiling current capabilities up to 10 A DC for up to 10 seconds during dynamic grid disturbances).

Excitation Output Voltage: Delivers high-efficiency pulse-width modulation (PWM) output voltage regulation up to 250 V DC.

Microprocessing Architecture: High-speed digital microprocessor implementing real-time control loop execution, closed-loop PID parameter adjustment, and safety tracking algorithms.

Control Loop Modes: Fully configurable for Automatic Voltage Regulation (AVR), Field Current Regulation (FCR), Power Factor Regulation (PF), and Reactive Power Regulation (VAR).

Integrated Limiters: Built-in standard protective limiters including Over-Excitation Limiter (OEL), Under-Excitation Limiter (UEL), Stator Current Limiter, and V/Hz (Volts-per-Hertz) overfluxing protection.

Communication Interfaces: Onboard connectivity featuring Modbus RTU, Modbus TCP, and CANopen network protocols for smooth interaction with industrial PLCs or central DCS platforms.

I/O Configuration: Compact hardware infrastructure containing configurable analog inputs/outputs and fast digital inputs/outputs for localized field control sequencing.

Form Factor: Ultra-compact, space-saving DIN-rail mountable housing designed for easy mechanical integration into small control panels.

Environmental Durability: Rugged industrial design with conformal-coated electronic board assemblies, capable of operating reliably across an ambient temperature range of -25°C to +70°C.

Industrial Sectors:

Small-Scale Power Generation (Micro-Hydro, Biomass, and Diesel Power Plants), Marine Auxiliary Power Systems, Industrial Co-generation Facilities, and Emergency Backup Generator Sets.

Application Scenarios:

1. Small Synchronous Generator Excitation: Serves as the primary automatic voltage regulator (AVR) for smaller synchronous machines up to approximately 10 MVA, maintaining strict generator terminal voltage stability under varying network loads.

2. Emergency Backup Power Generation: Deployed within critical hospital, data center, or industrial backup diesel generator panels to guarantee rapid voltage build-up and stable islanded grid operation during main grid failures.

3. Marine Auxiliary Genset Stabilization: Installed inside the auxiliary power control cabinets of commercial ships to manage generator voltage output and protect shipboard distribution networks from dynamic load imbalances.

4. Industrial Synchronous Motor Excitation: Utilized within processing facilities to manage the excitation loops of smaller synchronous motors, optimizing localized reactive power levels and facility energy efficiency.
