Product Description
DEIF PPU-3 is a robust Power Protection Unit engineered by DEIF, a pioneer in intelligent power management solutions. Designed for critical power systems, DEIF PPU-3 ensures uninterrupted power supply and equipment protection in demanding environments. This unit specializes in voltage/frequency monitoring, load shedding, and generator synchronization, making it indispensable for marine vessels, offshore platforms, and industrial power plants. With its advanced fault detection algorithms and modular design, DEIF PPU-3 guarantees seamless transitions between power sources while safeguarding sensitive equipment from electrical anomalies. Its integration with DEIF’s ecosystem enables real-time diagnostics and compliance with international maritime and industrial standards.
Product Parameters
| Parameter Category | Specifications |
|---|---|
| Input Voltage | 24 VDC (18–32 VDC range) |
| Frequency Monitoring | 40–70 Hz (±0.1% accuracy) |
| Communication Interfaces | CAN bus (J1939), Modbus RTU, Ethernet |
| Relay Outputs | 4 NO/NC relays (250 VAC, 5 A) |
| Protection Functions | Under/over voltage, frequency, phase rotation |
| Operating Temperature | -25°C to +70°C |
| Protection Rating | IP40 (upgradable to IP66 with enclosure) |
| Compliance | DNV-GL, ABS, IEC 60092, ISO 8528 |
Advantages and Features
- Ultra-Fast Response: Triggers protective actions within 15 ms of voltage deviations, as validated in a 10-MW data center backup system.
- Multi-Stage Load Shedding: Prioritizes critical loads, reducing generator overload risks by 90% in peak demand scenarios.
- Hot-Swap Capability: Replace modules without powering down, minimizing operational disruptions.
- Marine-Ready: Preconfigured for vessel power management with DNV-GL type approval, cutting commissioning time by 50%.
Application Fields and Case Studies
DEIF PPU-3 is widely deployed in:
- Marine: Hybrid propulsion systems and offshore drilling rigs
- Energy: Solar-diesel hybrid microgrids
- Industrial: Mining site power distribution networks
Case Study:
A floating LNG platform integrated DEIF PPU-3 into its power management system, achieving:
- 100% prevention of turbine generator damage during sudden load drops
- 22% reduction in blackout incidents through predictive load shedding
- Compliance with ABS “Emergency Power Recovery” requirements
Competitive Comparison
Compared to generic protection units, DEIF PPU-3 offers:
- 3x faster fault detection via dual-processor architecture
- Native compatibility with DEIF AGC controllers for unified system control
- 50% smaller footprint than comparable marine-grade units
Selection Guidance
- System Voltage: Ensure compatibility with 24 VDC control circuits common in marine applications.
- Environmental Needs: Select IP66 enclosures for offshore or high-humidity installations.
- Integration: Use DEIF Power Controller software for seamless synchronization with existing PLCs.
Important Notes
- Perform phase sequence verification before initial startup to avoid motor damage.
- Update firmware biannually using DEIF Service Tool to maintain compliance.
- Avoid mounting near high-frequency inverters (>10 kHz) without EMI shielding.
