Core Characteristics
Nominal input voltage is 24 VDC, supporting multi-channel isolated power output for marine control peripherals. Built-in independent earth fault detection circuit with adjustable sensitivity to detect insulation faults in 24V DC distribution loops. Equipped with built-in fusing protection for each power branch to prevent fault spread across the whole system. Multiple LED indicator lights display power supply status, earth fault alarm and channel abnormal conditions for rapid on-site troubleshooting. Heavy-duty screw terminal connectors provide stable wiring connection under continuous marine vibration. Robust metal housing structure enhances mechanical shock resistance, suitable for installation inside engine room control cabinets. Internal circuit boards adopt conformal coating to resist salt mist, humidity and corrosive atmosphere in marine environments. The module complies with international marine equipment standards and satisfies strict EMC requirements against interference from marine frequency converters and large power equipment. It supports seamless matching with Wärtsilä IAS automation system and can be directly used for original spare replacement. Continuous stable operation can be realized within 5% to 95% non-condensing relative humidity environment. Standard fixed mounting structure simplifies installation and disassembly work during ship maintenance and overhaul.
