HV Shore Power Supply
Product Overview:
LCX Power SA33 series containerized high-voltage shore power supply is an integrated prefabricated shore power equipment, divided into High In Low Out and High In High Out two types.
Adopting IGBT/PWM pulse width modulation control technology, it converts high-voltage grid power into stable, adjustable high-quality AC power for berthed vessels.
The whole system is built in container cabinet with IP65 outdoor protection grade, suitable for harsh coastal port environment.
It features high efficiency, low waveform distortion and comprehensive electrical protection.
Available capacity ranges from 300kVA to 5000kVA, to meet power demands of various large and medium-sized ships.
Typical Applications：
1、Power supply for large container ships, bulk carriers and cruise ships at berth
2、New port & shipyard shore power renovation project
3、Offshore terminal, coastal industrial dock vessel power supply
4、Ship repair & vessel construction shore power connection
5、Marine power replacement to reduce ship engine exhaust emission
