AC SYSTEM |
| 1. |
|
A.C. SYSTEM: Vessel is fitted with two (2) 240 VAC and one (1) 120 VAC shore inlets. House shore power is fed through a 12KVA isolation transformer. The air conditioning may be operated from the house shore power or from its own dedicated shore power inlet which is equipped with a galvanic isolator. The air conditioning may be operated from either 50 Hz or 60 Hz current. Current is distributed through custom PAE electrical panels containing 240 VAC and 120 VAC sections, volt and amp meters and individual breakers for functions. (PAE to supply Isolation Transformer). |
|
A. |
Two (2) Xantrex SW4024 4KW 24 volt battery charger/inverters with remote control panels. Inverters are installed in a "series/stack" configuration enabling the vessel to have 120 VAC and 240 VAC inverted power. Electrical panel is fitted with an inverter bypass switch in the event of failure. PAE to supply Inverters. |

|
E. |
Two (2) Glendinning shore power cord retrieval systems with barrels located in the transom. One each for the 240V house shore power and air conditioning shore power. Each system to be provided with 85' from the transom of shore power cable. PAE to supply. |
|
F. |
Std. Shore power inlets located on the port side of foredeck. |
|
|
DC SYSTEM |
| 2. |
|
DC power is provided by 24 VDC and 12 VDC systems. The primary DC system is 24 volts and the secondary system is 12 volts for any equipment that is only available in 12 volts. |
|
|
BATTERIES |
|
A. |
Standard batteries are located per PAE machinery drawing #N68-00-C01 and are provided as follows: |
|
|
24 VDC house battery bank - Consists of twelve (12) 8D, 12V "Lifeline" AGM @ 255 Ah each. Two groups of six (6) batteries each are connected in parallel. The two groups are connected in series to provide a total battery bank rating of 1530 amps at 24V. Includes Link 10 battery monitor. |
|
|
12 VDC power is supplied to the pilot house distribution panel by one (1) group 31 "Lifeline" AGM @ 105 Ah battery. A Centaur 12VDC 30amp Three Bank Output battery charger charges the batteries through the inverter (PAE to supply). |
|
|
Main engine starting - 2-4D "Lifeline" AGM @ 255 Ah each connected in series for 24 volt starting. Switching logic to parallel with 24V house bank for emergency starting. |
|
|
Generator starting- 2-Group 31 “Lifeline” AGM @ 105 Ah each connected in series for 24volt starting. Switching logic to parallel with 24V house bank for emergency starting. |
|
|
Wing engine starting- 2-Group 31 “Lifeline” AGM @ 105 Ah each connected in series for 24volt starting. Switching logic to parallel with 24V house bank for emergency starting. |
|

|
|
BATTERY CHARGING |
|
B. |
24 volt battery charging is provided in the following ways: |
|
|
Trace inverter/chargers provide a total of 240 amps at 24 volts |
|
|
One (1) "Centaur" 100 amp charger which operates on 90-265VAC input, 45-65Hz, 3600VA three bank outputs, lead acid/gel/agm. This charger is a back up to the Trace inverter/charger and serves as a battery charger when the vessel is in a 50Hz environment. |
|
|
Main engine starting battery bank is charged from the house bank thru a diode isolator. PAE to supply. |
|
|
25 KW NL generator has its own 20 amp 24V alternator which charges its starting battery |
|
|
Wing engine has its own 100 amp 24V alternator which charges its starting battery |
