Advanced Shore to Ship Power Technology
This Shore to Ship Power Voltage Converter employs advanced mains-frequency isolation technology, establishing a robust electrical isolation barrier between shore power and vessel equipment. This technology effectively blocks potential adverse factors from the shore power supply, such as electrical interference, voltage fluctuations, and harmonics, delivering a stable and clean power source to onboard equipment.
Regardless of variations in shore power quality, the converter maintains stable output voltage and frequency. This ensures optimal operation of onboard equipment including lighting systems, ventilation units, pumps, and electronic instruments, significantly reducing equipment failure rates and extending service life.
🛡️ Durable Outdoor Design
Given the complex and variable conditions encountered during vessel berthing, the converter demonstrates exceptional outdoor adaptability. Its housing is constructed from high-strength, corrosion-resistant materials, featuring waterproof and dustproof capabilities with an ingress protection rating designed to withstand rainwater, seawater splashes, and adverse weather conditions. Whether deployed in humid coastal ports or wind-swept inland river terminals, the converter operates with consistent reliability.
Harmonic Suppression
To counter electromagnetic interference, the unit employs special winding designs and shielding measures. This filters out over 90% of high-frequency harmonics, ensuring pure and stable output voltage (error ≤ ±1%).
Dynamic Compensation
Through an integrated tap changer, voltage regulation within ±5% is achieved. This maintains output voltage near rated values even during fluctuations in shore power supply or sudden vessel load changes.
High Efficiency
Utilising low-loss core materials and optimised winding techniques to achieve over 92% conversion efficiency, minimising iron losses and supporting green shipping initiatives.
Multi-Layer Protection
Equipped with overcurrent, overvoltage, overload, short-circuit and thermal protection. It disconnects power within 0.1 seconds upon detecting anomalies to prevent fault escalation.
Application Scenarios
