DEIF PPU-3 Technical Parameters

1.Input specification: 3‑phase voltage (100–690V AC) / current (1/5A AC) input, digital dry‑contact input, 8–36V DC auxiliary power input;

2.Output specification: Relay trip/control output, RS485/Modbus TCP/CANbus communication output, LCD display data output;

3.Power supply requirement: 12/24V DC nominal (8–36V DC operating), 11W maximum power consumption; 110–240V AC optional power supply.

Main Functions

1.Generator protection: overload, underload, overvoltage, undervoltage, short circuit, reverse power, and frequency abnormality;

2.Automatic synchronization: precise generator synchronization with other units for parallel operation;

3.Load sharing: proportional load distribution among parallel generators to prevent overload;

4.Real‑time monitoring: three‑phase current, voltage, frequency, power factor, and alarm status display;

5.Remote control: integration with PLC/SCADA for remote monitoring, parameter adjustment, and start/stop control ;

6.Engine control: optional engine interface card for start/stop control and backup monitoring .

Industrial Application Cases

1.Marine industry: Ship and offshore platform generator control, synchronization, and protection systems ;

2.Power generation: Industrial backup generator sets and distributed power plants;

3.Oil and gas: Offshore platform and refinery power management systems;

4.Data centers: UPS and backup generator control systems for critical power reliability;

5.Construction: Temporary power generator sets for construction sites and remote areas.

Product Features

1.Compact all‑in‑one design integrating generator protection, synchronization, and load sharing;

2.Galvanically isolated three‑phase measuring circuits for accurate and safe signal acquisition ;

3.Multiple control modes: load sharing, fixed power, fixed frequency, and droop control ;

4.Separate LCD display (DU‑2) with dimmable backlight for real‑time data and alarm monitoring ;

5. Multi‑protocol communication: RS485, Modbus TCP, CANbus, and J1939 engine bus for system integration;
