Product Description

ABB LDGRB-01 | 3BSE013177R1

Load Distributor & Generator Parallel Control Module for Multi-Unit Power Systems

1. Product Overview

The ABB LDGRB-01 (3BSE013177R1) is a dedicated load distributor and generator parallel control module, engineered to manage power sharing and synchronization of up to 16 generators in industrial power plants, marine vessels, and distributed generation systems (IEC 61850/IEEE 1547 compliant). It delivers ±1% load distribution accuracy, ±0.25% frequency regulation, and ±0.5% voltage control precision, with real-time monitoring of AC voltage (0-300V) and current (0-5A) for each unit. The module integrates dual CAN/RS485 communication ports for seamless integration with ABB UNITROL or third-party genset controllers, plus built-in overcurrent/overvoltage protection and thermal shutdown to ensure system stability during load transients. With a<100ms response time and -25°C to +70°C operating range, it excels in 24/7 critical power applications requiring high reliability and fast fault recovery.

4. Installation & Maintenance

Installation: Mount on 35mm DIN rail; connect 24 Vdc power (reverse polarity protected); wire CAN/RS485 to genset controllers; connect voltage/current transformers (CT/PT); power on and verify LED status (Green=Power, Blue=Sync, Amber=Warning, Red=Fault).

Maintenance: Weekly: Check LED indicators and communication link; Monthly: Verify load distribution accuracy via HMI; Annual: Calibrate voltage/current sensors, update firmware, and test overload response.

Safety Notes: Use shielded twisted-pair for CAN/RS485 (min 1.5 mm²); isolate CT/PT circuits from control wiring; follow local electrical codes for high-voltage connections.
