Core Product Characteristics
Ultra-fast synchronization algorithm completes phase lock within 100ms to avoid large switching inrush current; built-in multi-level protection including over/under voltage, over/under frequency, phase imbalance and reverse power; conformal coated circuit board resists marine salt fog, moisture and corrosive gas; standard Delomatic rack backplane plug-in design supporting hot-swap maintenance without system shutdown; real-time LED status indicators for power, bus communication and channel faults; fully compatible with all Delomatic series control and I/O modules; high ESD and surge immunity to suppress electromagnetic interference from marine heavy-duty equipment; supports online parameter modification without power interruption.
Wiring Instruction
Insert the module into standard Delomatic DGU rack backplane to obtain power and ARC-net bus connection. Connect generator PT voltage and CT current sampling signals to front screw terminals with shielded twisted cables, single-point ground shielding layers on cabinet earth bar. Wire 4–20mA analog trimming output to governor and AVR excitation regulator. Separate high-power power wiring and weak signal wiring to reduce crosstalk and signal distortion.
