DEIF PPU/2/GS

Technical Specifications

Function Features

• Precise Synchronization: Automatically matches voltage, frequency, and phase angle for safe generator paralleling; reduces transient currents and mechanical stress on generators and switchgear.
• Comprehensive Protection: Monitors overvoltage, undervoltage, overfrequency, underfrequency, overcurrent, reverse power, and phase loss; triggers instant shutdown to prevent equipment damage.
• Load Sharing & Management: Distributes load evenly across paralleled generators using droop control or isochronous control; adjusts generator output to maintain stable voltage and frequency.
• Configurable Control Logic: Supports manual, semi‑automatic, and fully automatic operation; user‑programmable setpoints for all protection and control parameters via front panel or software.
• Analog Output Integration: 0–20 mA outputs provide real‑time data for SCADA systems; configurable for active power, reactive power, voltage, current, or frequency monitoring.
• Isolated Relay Outputs: 4 independent relays for alarm, shutdown, and control functions; 250 VAC/24 VDC rating ensures compatibility with industrial switchgear.
• Harsh Environment Operation: -25°C to +70°C operating temperature; vibration and shock resistance per IEC 60068‑2‑6/2‑27; suitable for marine and offshore installations.
• Safety Compliance: 600V CAT III rating; meets IEC 61010‑1 for electrical safety; marine certifications (ABS, DNV‑GL) ensure shipboard reliability.
• Easy Commissioning: Front panel pushbuttons and LCD for local configuration; PC software for advanced setup, data logging, and diagnostics.
• Redundant Power Supply: 12/24 VDC input with reverse polarity protection; 1 A fuse prevents damage from overcurrent.

Application Scenarios

• Marine Power Systems: Main and emergency generator sets on cargo ships, tankers, and cruise liners; ensures reliable power for propulsion, navigation, and hotel loads; complies with marine classification society standards (ABS, DNV‑GL).
• Offshore Installations: Oil rigs, wind farms, and subsea facilities; paralleling of diesel generators for continuous power; protection against harsh weather and saltwater corrosion.
• Industrial Power Plants: Combined heat and power (CHP) systems; backup generator synchronization with grid; load sharing for peak demand management; reduces energy costs by optimizing generator operation.
• Data Centers: Uninterruptible power supply (UPS) systems with generator backup; fast paralleling to prevent data loss during grid outages; precise voltage and frequency control for sensitive IT equipment.
• Hospitals & Critical Facilities: Emergency power systems for hospitals, airports, and military bases; automatic transfer and paralleling to ensure continuous power for life‑saving equipment and critical operations.
• Mining & Construction: Mobile power plants and temporary generator setups; paralleling for high load requirements; protection against overcurrent and voltage fluctuations in remote locations.
• Renewable Energy Integration: Solar and wind farm backup generators; synchronization with grid to maintain power quality; load shedding during low renewable energy output.

Compatibility and Integration

• Generator Compatibility: Works with all major generator brands (Caterpillar, Cummins, MTU, Wärtsilä); supports 1 A/5 A CTs and standard voltage transformers.
• Switchgear Integration: Interfaces with circuit breakers, contactors, and transfer switches via relay outputs; 250 VAC/24 VDC rating matches industrial switchgear specifications.
• Communication Protocols: Optional RS‑485 (Modbus RTU) for SCADA integration; CANbus for marine automation systems; Ethernet (TCP/IP) for remote monitoring and control.
• Software Tools: DEIF MULTI‑LINE Configuration Software; data logging and trend analysis for predictive maintenance; remote diagnostics via PC or HMI.
