PGH series marine switchboard applies to AC and DC systems under three-phase AC720V (50HZ/60H) and DC220V, used to control, monitor, protect the generators and power distribution.
　　Marine switchboard varies by ship. It can be designed and produced according to customer’s technical requirements To meet different requirements of customers, PMS has three mode, i.e. manual, semi-automatic
and automatic.
　　It can be declared for CCS, ABS, GL, BV, KR, RINA, DNV and other marine products inspection certification.

Automatic Station Management System:

1. when electric network is power off, it can automatically start the diesel generator in 40 seconds and automaticallyswitch on for power supply.
2. When diesel generators supplys, if the electric network load exceeds 90% of unit capacity, it will automatically
start a stand by diesel generator, and automatically adjust and switch on, so as to achieve Dual parallel generating
power.
3. When electric network loads more than 95% of total capacity, it will unload non-essential load automatically after1 minute delay (time adjustable).
4. In Dual Parallel run of diesel generators, if electric network load is less than 40% of power plant capacity, the latter parallel load units automatically transfer and splitting, off from the electric network.
5. Heavy load inquiry function: Inquiry is necessary before starting large capacity heavy load, calculated by the
automatic station. If the power plant capacity allows, then starting command issues; if the power plant capacity is
low and as isolated operating, diesel generator will be started automatically. Large-capacity load is only allowed to
start after staring commend is issued by the auto-power station, so as to ensure that power will not overload trip due
to starting large power generator.
6. Automatically self-check function
7. Extend alarm function as required by AUTO-O specification.
8. Important load start in turn.
9. with a standard RS485 or RS232 external control interface.
The management module adopts SELCO, SIGMA and other famous brands, so as to achieve automatic
frequency modulation, ensuring continuity of the swith board.
