Cummins PCC3300MLD (PowerCommand 3.3 Controller)

Advanced Paralleling & Load Demand Generator Control Module

The Cummins PCC3300MLD (PowerCommand 3.3) is an advanced microprocessor-based generator control system designed for intelligent power management, paralleling, and automatic mains failure (AMF) operation. Built for reliability and flexibility, it offers comprehensive monitoring, protection, and load sharing for both diesel and gas generator sets.

The PCC3300MLD integrates automatic start/stop control, voltage regulation, synchronization, and real-time engine monitoring into a single compact unit. Its Masterless Load Demand (MLD) feature allows multiple generators to operate efficiently without a dedicated master controller, reducing fuel consumption and maximizing performance.

Key Features:

• Automatic mains failure (AMF) and generator control

• Paralleling and load sharing for multiple gensets

• Built-in digital voltage regulation

• Real-time monitoring of voltage, current, kW, kVAr, and frequency

• Masterless Load Demand (MLD) operation for efficiency

• Modbus communication and InPower PC software support

• High-resolution LCD display with multilingual interface

• Event and fault logging for easy diagnostics
