SUMMER SHUTDOWN 2017
Every Year we close our doors for two weeks to give our staff a well earned rest. This year the office will be closed from 4th August 2017 to 21th August 2017.
The Website will remain open and operational, however orders, and enquiries, will NOT be processed until our return on the 21th. Please allow for this delay when ordering.
Thank you for understanding and we wish you all a pleasant summer with lots of sailing. The Team @ Yachtbits
Diode battery isolators allow simultaneous charging of two or more batteries from one alternator, without connecting the batteries together. Discharging the accessory battery for example will not result in also discharging the starter battery. The Argo battery isolators feature a low voltage drop thanks to the use of Schottky diodes: at low current the voltage drop is approximately 0,3 V and at the rated output approximately 0,45 V. All models are fitted with a compensation diode that can be used to slightly increase the output voltage of the alternator. This compensates for the voltage drop over the diodes in the isolator.
Please ask for specialist advice when installing a diode isolator. Simply inserting the isolator in the cabling between the alternator and the batteries will slightly reduce charge voltage. The result can be that batteries are not charged to the full 100% and age prematurely.
All models are fitted with a compensation diode that can be used to slightly increase the output voltage of the alternator. This compensates
for the voltage drop over the diodes in the isolator. Care should be taken however to keep cable lengths short and of sufficient cross section.
Alternator energize input
Some alternators need DC voltage on the B+ output to start charging. Obviously, DC will be present when the alternator is directly connected to a battery. Inserting a Diode or FET splitter will however prevent any return voltage/current from the batteries to the B+, and the alternator will not start. The new “AC” diode isolators feature a special current limited energize input that will power the B+ when the engine run/stop switch is closed.
