Introduction to DEIF PPM3-6DG-6H3-1F1
Product Description
The DEIF PPM3-6DG-6H3-1F1 is a high-performance power management controller designed for distributed energy systems, generator sets, and industrial power grids. Manufactured by DEIF, a global leader in energy management solutions, this controller specializes in monitoring, controlling, and optimizing power distribution across multiple sources, including generators, renewable energy systems (solar, wind), and utility grids. It is widely deployed in applications such as data centers, remote off-grid installations, marine vessels, and critical infrastructure requiring reliable power supply.
Featuring a modular design and advanced algorithms, the PPM3-6DG-6H3-1F1 enables seamless synchronization of power sources, load sharing, and protection against electrical faults (e.g., overvoltage, underfrequency). Its robust construction ensures operation in harsh environments with temperature fluctuations, vibration, and electromagnetic interference, while flexible communication interfaces allow integration with SCADA systems and remote monitoring platforms. The controller’s “6DG” and “6H3” designations indicate specific hardware configurations, including input/output capabilities and communication protocols, tailored for complex multi-source power systems.

Usage Methods
- Installation:
-
- Mount the controller in a control cabinet using DIN rail or panel-mounting brackets, ensuring vertical orientation for optimal heat dissipation.
-
- Position away from high-voltage cables, transformers, and sources of electromagnetic interference to minimize measurement errors.
-
- Ensure a minimum clearance of 50mm around the controller for ventilation and wiring access.
- Wiring and Connection:
-
- Connect voltage transformers (VTs) and current transformers (CTs) to the measurement inputs, following polarity markings to ensure correct phase alignment.
-
- Wire control outputs (relays, analog signals) to generators, breakers, or contactors, ensuring load currents do not exceed relay ratings.
-
- Establish communication links via Ethernet or RS485, using shielded twisted-pair cables with shields grounded at both ends.
-
- Connect auxiliary power (85-265V AC/DC) to the dedicated terminals, using a fused circuit (1A) for protection.
- Configuration and Commissioning:
-
- Use DEIF’s Power Management Toolkit software to configure system parameters, including generator ratings, synchronization settings, and protection thresholds.
-
- Calibrate voltage and current measurements using reference sources to ensure accuracy across the operating range.
-
- Program load-sharing logic and priority settings for power sources (e.g., prioritize solar over diesel generators when available).
-
- Test synchronization between parallel generators by simulating load changes and verifying frequency/voltage stability.
- Operation and Maintenance:
-
- Monitor system status via the front-panel LCD or remote software, checking for alarms (e.g., overcurrent, synchronization failure).
-
- Perform monthly inspections: verify wiring tightness, clean dust from ventilation slots, and check for error codes.
-
- Recalibrate measurement channels annually using certified test equipment to maintain accuracy.
-
- Update firmware quarterly via USB or Ethernet to access new features and security patches.
System Introduction
The DEIF PPM3-6DG-6H3-1F1 operates as the central intelligence in multi-source power systems, integrating with four key layers:
- Sensing Layer: Measures voltage, current, and frequency from generators, grids, and renewable sources via VTs and CTs, converting analog signals to digital data.
- Processing Layer: Analyzes data using load-sharing, synchronization, and protection algorithms to optimize power distribution and prevent overloads or instability.
- Control Layer: Activates relays and analog outputs to adjust generator speed, open/close breakers, or curtail renewable energy production based on system conditions.
- Communication Layer: Transmits real-time data to SCADA systems or cloud platforms, enabling remote monitoring, historical trending, and predictive maintenance.
In a remote mining camp application, the controller manages three diesel generators and a solar array. It synchronizes generator output with solar power, prioritizing solar energy to reduce fuel consumption. During peak demand, it starts additional generators and shares load evenly to maintain stable voltage (±2% of 400V). If a generator fails, the controller instantly isolates the fault and redistributes load to remaining sources, preventing blackouts.
