DEIF PPM-3 | DG Protection and Power Management

The DEIF PPM-3 is an advanced, integrated Protection and Power Management unit designed for generator control systems. It is engineered to handle complex tasks including synchronizing, load sharing, and comprehensive protection for diesel generators (DG). The 250VAC variant is built to operate reliably in harsh maritime, industrial, and power plant environments, ensuring stable power delivery and seamless grid interaction.

📖 Product User Guide

Installation must be performed by a qualified engineer. Mount the DEIF PPM-3 in a suitable control panel cutout using the provided mounting brackets. Wire the CT/VT inputs according to the installation manual to ensure accurate phase measurement. Connect the CANbus interface for load sharing between multiple units. Before commissioning, use the DEIF Utility Software (USW) to configure the protection thresholds (overvoltage, undervoltage, frequency, etc.) and parallel parameters. Always verify the synchronization pulse and breaker logic via secondary testing before attempting a live parallel connection with the grid or other generators.

❓ Frequently Asked Questions (Q&A)

What is the main advantage of the PPM-3 over standard generator controllers? The PPM-3 offers “all-in-one” functionality. While basic controllers only monitor engine status, the PPM-3 integrates complex synchronization and load-sharing algorithms, removing the need for external synchronizers and load-share units.

How does the unit handle parallel operation? The PPM-3 communicates with other units via a dedicated CANbus link to exchange information about engine status, power output, and system frequency. It uses this data to adjust the governor and AVR (Automatic Voltage Regulator) signals for perfectly synchronized load sharing.

What should I do if I see a “Sync Failed” alarm? This indicates that the generator frequency, voltage, or phase angle could not be matched to the busbar within the programmed time limit. Check the engine’s speed control and governor response, and verify that the voltage sensing lines are wired correctly.
